KeyboardModifier Modifier

PySide6.QtCore.Qt.Orientation

(inherits enum.Flag) This type is used to signify an object’s orientation.

Constant	Description
Qt.Horizontal
Qt.Vertical

Orientation is used with QScrollBar for example.

Constant	Description
Qt.TabFocus	the widget accepts focus by tabbing.
Qt.ClickFocus	the widget accepts focus by clicking.

This enum describes how to repeat or stretch the parts of an image when drawing.

Constant	Description
Qt.StretchTile	Scale the image to fit to the available area.
Qt.RepeatTile	Repeat the image until there is no more space. May crop the last image.
Qt.RoundTile	Similar to Repeat, but scales the image down to ensure that the last tile is not cropped.

New in version 4.6.

PySide6.QtCore.Qt.AlignmentFlag

(inherits enum.IntFlag) This enum type is used to describe alignment. It contains horizontal and vertical flags that can be combined to produce the required effect.

The TextElideMode enum can also be used in many situations to fine-tune the appearance of aligned text.

The horizontal flags are:

Constant	Description
Qt.AlignLeft	Aligns with the left edge.
Qt.AlignRight	Aligns with the right edge.
Qt.AlignHCenter	Centers horizontally in the available space.
Qt.AlignJustify	Justifies the text in the available space.

The vertical flags are:

Constant	Description
Qt.AlignTop	Aligns with the top.
Qt.AlignBottom	Aligns with the bottom.
Qt.AlignVCenter	Centers vertically in the available space.
Qt.AlignBaseline	Aligns with the baseline.

You can use only one of the horizontal flags at a time. There is one two-dimensional flag:

Constant	Description
Qt.AlignCenter	Centers in both dimensions.

You can use at most one horizontal and one vertical flag at a time. Qt::AlignCenter counts as both horizontal and vertical.

Three enum values are useful in applications that can be run in right-to-left mode:

Constant	Description
Qt.AlignAbsolute	If the widget’s layout direction is RightToLeft (instead of LeftToRight , the default), Qt::AlignLeft refers to the right edge and Qt::AlignRight to the left edge. This is normally the desired behavior. If you want Qt::AlignLeft to always mean “left” and Qt::AlignRight to always mean “right”, combine the flag with Qt::AlignAbsolute.
Qt.AlignLeading	Synonym for Qt::AlignLeft.
Qt.AlignTrailing	Synonym for Qt::AlignRight.

Masks:

Constant	Description
Qt.AlignHorizontal_Mask
Qt.AlignVertical_Mask

Conflicting combinations of flags have undefined meanings.

PySide6.QtCore.Qt.TextFlag

(inherits enum.IntFlag) This enum type is used to define some modifier flags. Some of these flags only make sense in the context of printing:

Constant	Description
Qt.TextSingleLine	Treats all whitespace as spaces and prints just one line.
Qt.TextDontClip	If it’s impossible to stay within the given bounds, it prints outside.
Qt.TextExpandTabs	Makes the U+0009 (ASCII tab) character move to the next tab stop.
Qt.TextShowMnemonic	Displays the string “&P” as P For an ampersand, use “&&”.
Qt.TextWordWrap	Breaks lines at appropriate points, e.g. at word boundaries.
Qt.TextWrapAnywhere	Breaks lines anywhere, even within words.
Qt.TextHideMnemonic	Same as Qt::TextShowMnemonic but doesn’t draw the underlines.
Qt.TextDontPrint	Treat this text as “hidden” and don’t print it.
Qt.TextIncludeTrailingSpaces	When this option is set, naturalTextWidth() and naturalTextRect() will return a value that includes the width of trailing spaces in the text; otherwise this width is excluded.
Qt.TextJustificationForced	Ensures that text lines are justified.

You can use as many modifier flags as you want, except that Qt::TextSingleLine and Qt::TextWordWrap cannot be combined.

Flags that are inappropriate for a given use are generally ignored.

PySide6.QtCore.Qt.TextElideMode

This enum specifies where the ellipsis should appear when displaying texts that don’t fit:

Constant	Description
Qt.ElideLeft	The ellipsis should appear at the beginning of the text.
Qt.ElideRight	The ellipsis should appear at the end of the text.
Qt.ElideMiddle	The ellipsis should appear in the middle of the text.
Qt.ElideNone	Ellipsis should NOT appear in the text.

Qt::ElideMiddle is normally the most appropriate choice for URLs (e.g., “ http://bugreports.qt…/QTWEBSITE-13/ “), whereas Qt::ElideRight is appropriate for other strings (e.g., “ Deploying Applications on Ma… “).

textElideMode elidedText() AlignmentFlag elideMode

PySide6.QtCore.Qt.WhiteSpaceMode

This enum describes the types of whitespace mode that are used by the QTextDocument class to meet the requirements of different kinds of textual information.

Constant	Description
Qt.WhiteSpaceNormal	The whitespace mode used to display normal word wrapped text in paragraphs.
Qt.WhiteSpacePre	A preformatted text mode in which whitespace is reproduced exactly.
Qt.WhiteSpaceNoWrap

PySide6.QtCore.Qt.HitTestAccuracy

This enum contains the types of accuracy that can be used by the QTextDocument class when testing for mouse clicks on text documents.

Constant	Description
Qt.ExactHit	The point at which input occurred must coincide exactly with input-sensitive parts of the document.
Qt.FuzzyHit	The point at which input occurred can lie close to input-sensitive parts of the document.

PySide6.QtCore.Qt.WindowType

(inherits enum.IntFlag) This enum type is used to specify various window-system properties for the widget. They are fairly unusual but necessary in a few cases. Some of these flags depend on whether the underlying window manager supports them.

The main types are

Constant	Description
Qt.Widget	This is the default type for QWidget . Widgets of this type are child widgets if they have a parent, and independent windows if they have no parent. See also Qt::Window and Qt::SubWindow.
Qt.Window	Indicates that the widget is a window, usually with a window system frame and a title bar, irrespective of whether the widget has a parent or not. Note that it is not possible to unset this flag if the widget does not have a parent.
Qt.Dialog	Indicates that the widget is a window that should be decorated as a dialog (i.e., typically no maximize or minimize buttons in the title bar). This is the default type for QDialog . If you want to use it as a modal dialog, it should be launched from another window, or have a parent and used with the windowModality property. If you make it modal, the dialog will prevent other top-level windows in the application from getting any input. We refer to a top-level window that has a parent as a secondary window.
Qt.Sheet	Indicates that the window is a sheet on macOS. Since using a sheet implies window modality, the recommended way is to use setWindowModality() , or open() , instead.
Qt.Drawer	Indicates that the widget is a drawer on macOS. This feature is obsolete. Setting the flag has no effect.
Qt.Popup	Indicates that the widget is a pop-up top-level window, i.e. that it is modal, but has a window system frame appropriate for pop-up menus.
Qt.Tool	Indicates that the widget is a tool window. A tool window is often a small window with a smaller than usual title bar and decoration, typically used for collections of tool buttons. If there is a parent, the tool window will always be kept on top of it. If there isn’t a parent, you may consider using Qt::WindowStaysOnTopHint as well. If the window system supports it, a tool window can be decorated with a somewhat lighter frame. It can also be combined with Qt::FramelessWindowHint. On macOS, tool windows correspond to the NSPanel class of windows. This means that the window lives on a level above normal windows making it impossible to put a normal window on top of it. By default, tool windows will disappear when the application is inactive. This can be controlled by the WA_MacAlwaysShowToolWindow attribute.
Qt.ToolTip	Indicates that the widget is a tooltip. This is used internally to implement tooltips .
Qt.SplashScreen	Indicates that the window is a splash screen. This is the default type for QSplashScreen .
Qt.SubWindow	Indicates that this widget is a sub-window, such as a QMdiSubWindow widget.
Qt.ForeignWindow	Indicates that this window object is a handle representing a native platform window created by another process or by manually using native code.
Qt.CoverWindow	Indicates that the window represents a cover window, which is shown when the application is minimized on some platforms.

There are also a number of flags which you can use to customize the appearance of top-level windows. These have no effect on other windows:

Constant	Description
Qt.MSWindowsFixedSizeDialogHint	Gives the window a thin dialog border on Windows. This style is traditionally used for fixed-size dialogs.

Note

The use of this flag is not recommended in multi-monitor environments. This is because the system will enforce that the window maintains its native size when moving it across screens. This is particularly undesirable when using monitors with different resolutions.

Constant	Description
Qt.MSWindowsOwnDC	Gives the window its own display context on Windows.
Qt.BypassWindowManagerHint	This flag can be used to indicate to the platform plugin that “all” window manager protocols should be disabled. This flag will behave different depending on what operating system the application is running on and what window manager is running. The flag can be used to get a native window with no configuration set.
Qt.X11BypassWindowManagerHint	Bypass the window manager completely. This results in a borderless window that is not managed at all (i.e., no keyboard input unless you call activateWindow() manually).
Qt.FramelessWindowHint	Produces a borderless window.

On X11, the result of the flag is dependent on the window manager and its ability to understand Motif and/or NETWM hints. Most existing modern window managers can handle this.

Note

If the window manager relies on the frame to interactively manipulate the window, the user can no longer move or resize the window via the window system, but this side effect should not be relied on. To produce a fixed size window that can not be resized, please set setMinimumSize() and setMaximumSize() to the same size.

Constant	Description
Qt.NoDropShadowWindowHint	Disables window drop shadow on supporting platforms.

The CustomizeWindowHint flag is used to enable customization of the window controls. This flag must be set to allow the WindowTitleHint, WindowSystemMenuHint, WindowMinimizeButtonHint, WindowMaximizeButtonHint and WindowCloseButtonHint flags to be changed.

Constant	Description
Qt.CustomizeWindowHint	Turns off the default window title hints.
Qt.WindowTitleHint	Gives the window a title bar.
Qt.WindowSystemMenuHint	Adds a window system menu, and possibly a close button (for example on Mac). If you need to hide or show a close button, it is more portable to use WindowCloseButtonHint.
Qt.WindowMinimizeButtonHint	Adds a minimize button. On some platforms this implies Qt::WindowSystemMenuHint for it to work.
Qt.WindowMaximizeButtonHint	Adds a maximize button. On some platforms this implies Qt::WindowSystemMenuHint for it to work.
Qt.WindowMinMaxButtonsHint	Adds a minimize and a maximize button. On some platforms this implies Qt::WindowSystemMenuHint for it to work.
Qt.WindowCloseButtonHint	Adds a close button. On some platforms this implies Qt::WindowSystemMenuHint for it to work.
Qt.WindowContextHelpButtonHint	Adds a context help button to dialogs. On some platforms this implies Qt::WindowSystemMenuHint for it to work.
Qt.MacWindowToolBarButtonHint	On macOS adds a tool bar button (i.e., the oblong button that is on the top right of windows that have toolbars).
Qt.WindowFullscreenButtonHint	On macOS adds a fullscreen button.
Qt.BypassGraphicsProxyWidget	Prevents the window and its children from automatically embedding themselves into a QGraphicsProxyWidget if the parent widget is already embedded. You can set this flag if you want your widget to always be a toplevel widget on the desktop, regardless of whether the parent widget is embedded in a scene or not.
Qt.WindowShadeButtonHint	Adds a shade button in place of the minimize button if the underlying window manager supports it.
Qt.WindowStaysOnTopHint	Informs the window system that the window should stay on top of all other windows. Note that on some window managers on X11 you also have to pass Qt::X11BypassWindowManagerHint for this flag to work correctly.
Qt.WindowStaysOnBottomHint	Informs the window system that the window should stay on bottom of all other windows.

Note

On X11, this hint will work only in window managers that support _NET_WM_STATE_BELOW atom. If a window always on the bottom has a parent, the parent will also be left on the bottom. This window hint is currently not implemented for macOS.

Note

On Windows, this will work only for frameless or full-screen windows.

Constant	Description
Qt.WindowTransparentForInput	Informs the window system that this window is used only for output (displaying something) and does not take input. Therefore input events should pass through as if it wasn’t there.
Qt.WindowOverridesSystemGestures	Informs the window system that this window implements its own set of gestures and that system level gestures, like for instance three-finger desktop switching, should be disabled.
Qt.WindowDoesNotAcceptFocus	Informs the window system that this window should not receive the input focus.
Qt.MaximizeUsingFullscreenGeometryHint	Informs the window system that when maximizing the window it should use as much of the available screen geometry as possible, including areas that may be covered by system UI such as status bars or application launchers. This may result in the window being placed under these system UIs, but does not guarantee it, depending on whether or not the platform supports it. When the flag is enabled the user is responsible for taking availableGeometry() into account, so that any UI elements in the application that require user interaction are not covered by system UI.
Qt.WindowType_Mask	A mask for extracting the window type part of the window flags.

windowFlags Window Flags Example

PySide6.QtCore.Qt.WindowState

(inherits enum.Flag) This enum type is used to specify the current state of a top-level window.

The states are

Constant	Description
Qt.WindowNoState	The window has no state set (in normal state).
Qt.WindowMinimized	The window is minimized (i.e. iconified).
Qt.WindowMaximized	The window is maximized with a frame around it.
Qt.WindowFullScreen	The window fills the entire screen without any frame around it.
Qt.WindowActive	The window is the active window, i.e. it has keyboard focus.

PySide6.QtCore.Qt.ApplicationState

(inherits enum.Flag) This enum type is used to specify the current state of the application.

The states are

Constant	Description
Qt.ApplicationSuspended	The application is about to suspend. When entering this state, the application should save its state, cease all activities, and be prepared for code execution to stop. While suspended, the application can be killed at any time without further warnings (e.g. when low memory forces the OS to purge suspended applications).
Qt.ApplicationHidden	The application is hidden and runs in the background. This is the normal state for applications that need to do background processing, like playing music, while the user interacts with other applications. The application should free up all graphical resources when entering this state.
Qt.ApplicationInactive	The application is visible, but not selected to be in front. On desktop platforms, this typically means that the user activated another application. On mobile platforms, it is more common to enter this state when the OS is interrupting the user with e.g. incoming calls or SMS-messages. While in this state, consider reducing CPU-intensive tasks.
Qt.ApplicationActive	The application is visible and selected to be in front.

PySide6.QtCore.Qt.ScreenOrientation

(inherits enum.Flag) This enum type specifies the various orientations a screen might have.

Constant	Description
Qt.PrimaryOrientation	The display’s primary orientation.
Qt.LandscapeOrientation	Landscape orientation, display width is greater than display height.
Qt.PortraitOrientation	Portrait orientation, display height is greater than display width, rotated 90 degree clockwise relative to landscape.
Qt.InvertedLandscapeOrientation	Inverted landscape orientation, rotated 180 degrees relative to landscape.
Qt.InvertedPortraitOrientation	Inverted portrait orientation, rotated 180 degrees relative to portrait.

PySide6.QtCore.Qt.WidgetAttribute

This enum type is used to specify various widget attributes. Attributes are set and cleared with setAttribute() , and queried with testAttribute() , although some have special convenience functions which are mentioned below.

Constant	Description
Qt.WA_AcceptDrops	Allows data from drag and drop operations to be dropped onto the widget (see setAcceptDrops() ).
Qt.WA_AlwaysShowToolTips	Enables tooltips for inactive windows.
Qt.WA_CustomWhatsThis	Indicates that the widget wants to continue operating normally in “What’s This?” mode. This is set by the widget’s author.
Qt.WA_DeleteOnClose	Makes Qt delete this widget when the widget has accepted the close event (see closeEvent() ).
Qt.WA_Disabled	Indicates that the widget is disabled, i.e. it does not receive any mouse or keyboard events. There is also a getter functions isEnabled() . This is set/cleared by the Qt kernel.
Qt.WA_DontShowOnScreen	Indicates that the widget is hidden or is not a part of the viewable Desktop.
Qt.WA_ForceDisabled	Indicates that the widget is explicitly disabled, i.e. it will remain disabled even when all its ancestors are set to the enabled state. This implies WA_Disabled. This is set/cleared by setEnabled() and setDisabled() .
Qt.WA_ForceUpdatesDisabled	Indicates that updates are explicitly disabled for the widget; i.e. it will remain disabled even when all its ancestors are set to the updates-enabled state. This implies WA_UpdatesDisabled. This is set/cleared by setUpdatesEnabled() .
Qt.WA_Hover	Forces Qt to generate paint events when the mouse enters or leaves the widget. This feature is typically used when implementing custom styles; see the Styles example for details.
Qt.WA_InputMethodEnabled	Enables input methods for Asian languages. Must be set when creating custom text editing widgets.
Qt.WA_KeyboardFocusChange	Set on a toplevel window when the users changes focus with the keyboard (tab, backtab, or shortcut).
Qt.WA_KeyCompression	Enables key event compression if set, and disables it if not set. By default key compression is off, so widgets receive one key press event for each key press (or more, since autorepeat is usually on). If you turn it on and your program doesn’t keep up with key input, Qt may try to compress key events so that more than one character can be processed in each event. For example, a word processor widget might receive 2, 3 or more characters in each text() , if the layout recalculation takes too long for the CPU. If a widget supports multiple character unicode input, it is always safe to turn the compression on. Qt performs key event compression only for printable characters. Modifier keys, cursor movement keys, function keys and miscellaneous action keys (e.g. Escape, Enter, Backspace, PrintScreen) will stop key event compression, even if there are more compressible key events available. Platforms other than Mac and X11 do not support this compression, in which case turning it on will have no effect. This is set/cleared by the widget’s author.
Qt.WA_LayoutOnEntireRect	Indicates that the widget wants QLayout to operate on the entire rect() , not only on contentsRect() . This is set by the widget’s author.
Qt.WA_LayoutUsesWidgetRect	Ignore the layout item rect from the style when laying out this widget with QLayout .
Qt.WA_MacOpaqueSizeGrip	Indicates that the native size grip should be opaque instead of transparent (the default). This attribute is only applicable to macOS and is set by the widget’s author.
Qt.WA_MacShowFocusRect	Indicates that this widget should get a QFocusFrame around it. Some widgets draw their own focus halo regardless of this attribute. Not that the focusPolicy also plays the main role in whether something is given focus or not, this only controls whether or not this gets the focus frame. This attribute is only applicable to macOS.
Qt.WA_MacNormalSize	Indicates the widget should have the normal size for widgets in macOS. This attribute is only applicable to macOS.
Qt.WA_MacSmallSize	Indicates the widget should have the small size for widgets in macOS. This attribute is only applicable to macOS.
Qt.WA_MacMiniSize	Indicates the widget should have the mini size for widgets in macOS. This attribute is only applicable to macOS.
Qt.WA_Mapped	Indicates that the widget is mapped on screen. This is set/cleared by the Qt kernel.
Qt.WA_MouseNoMask	Makes the widget receive mouse events for the entire widget regardless of the currently set mask, overriding setMask() . This is not applicable for top-level windows.
Qt.WA_MouseTracking	Indicates that the widget has mouse tracking enabled. See mouseTracking .
Qt.WA_Moved	Indicates that the widget has an explicit position. This is set/cleared by move() and by setGeometry() .
Qt.WA_NoChildEventsForParent	Indicates that the widget does not want ChildAdded or ChildRemoved events sent to its parent. This is rarely necessary but can help to avoid automatic insertion widgets like splitters and layouts. This is set by a widget’s author.
Qt.WA_NoChildEventsFromChildren	Indicates that the widget does not want to receive ChildAdded or ChildRemoved events sent from its children. This is set by a widget’s author.
Qt.WA_NoMouseReplay	Used for pop-up widgets. Indicates that the most recent mouse press event should not be replayed when the pop-up widget closes. The flag is set by the widget’s author and cleared by the Qt kernel every time the widget receives a new mouse event.
Qt.WA_NoMousePropagation	Prohibits mouse events from being propagated to the widget’s parent. This attribute is disabled by default.
Qt.WA_TransparentForMouseEvents	When enabled, this attribute disables the delivery of mouse events to the widget and its children. Mouse events are delivered to other widgets as if the widget and its children were not present in the widget hierarchy; mouse clicks and other events effectively “pass through” them. This attribute is disabled by default.
Qt.WA_NoSystemBackground	Indicates that the widget has no background, i.e. when the widget receives paint events, the background is not automatically repainted. Note: Unlike WA_OpaquePaintEvent, newly exposed areas are never filled with the background (e.g., after showing a window for the first time the user can see “through” it until the application processes the paint events). This flag is set or cleared by the widget’s author.
Qt.WA_OpaquePaintEvent	Indicates that the widget paints all its pixels when it receives a paint event. Thus, it is not required for operations like updating, resizing, scrolling and focus changes to erase the widget before generating paint events. The use of WA_OpaquePaintEvent provides a small optimization by helping to reduce flicker on systems that do not support double buffering and avoiding computational cycles necessary to erase the background prior to painting. Note: Unlike WA_NoSystemBackground, WA_OpaquePaintEvent makes an effort to avoid transparent window backgrounds. This flag is set or cleared by the widget’s author.
Qt.WA_OutsideWSRange	Indicates that the widget is outside the valid range of the window system’s coordinate system. A widget outside the valid range cannot be mapped on screen. This is set/cleared by the Qt kernel.
Qt.WA_PaintOnScreen	Indicates that the widget wants to draw directly onto the screen. Widgets with this attribute set do not participate in composition management, i.e. they cannot be semi-transparent or shine through semi-transparent overlapping widgets. Note: This flag is only supported on X11 and it disables double buffering. On Qt for Embedded Linux, the flag only works when set on a top-level widget and it relies on support from the active screen driver. This flag is set or cleared by the widget’s author. To render outside of Qt’s paint system, e.g., if you require native painting primitives, you need to reimplement paintEngine() to return 0 and set this flag.
Qt.WA_PaintUnclipped	Makes all painters operating on this widget unclipped. Children of this widget or other widgets in front of it do not clip the area the painter can paint on. This flag is only supported for widgets with the WA_PaintOnScreen flag set. The preferred way to do this in a cross platform way is to create a transparent widget that lies in front of the other widgets.
Qt.WA_PendingMoveEvent	Indicates that a move event is pending, e.g., when a hidden widget was moved. This flag is set or cleared by the Qt kernel.
Qt.WA_PendingResizeEvent	Indicates that a resize event is pending, e.g., when a hidden widget was resized. This flag is set or cleared by the Qt kernel.
Qt.WA_QuitOnClose	Indicates that the widget should be taken into account when deciding whether to quit the application when the last window is closed. This behavior can be modified with the quitOnLastWindowClosed property. By default this attribute is set for all widgets of type Window .
Qt.WA_Resized	Indicates that the widget has an explicit size. This flag is set or cleared by resize() and setGeometry() .
Qt.WA_RightToLeft	Indicates that the layout direction for the widget is right to left.
Qt.WA_SetCursor	Indicates that the widget has a cursor of its own. This flag is set or cleared by setCursor() and unsetCursor() .
Qt.WA_SetFont	Indicates that the widget has a font of its own. This flag is set or cleared by setFont() .
Qt.WA_SetPalette	Indicates that the widget has a palette of its own. This flag is set or cleared by setPalette() .
Qt.WA_SetStyle	Indicates that the widget has a style of its own. This flag is set or cleared by setStyle() .
Qt.WA_ShowModal	This attribute has been deprecated. Use windowModality instead.
Qt.WA_StaticContents	Indicates that the widget contents are north-west aligned and static. On resize, such a widget will receive paint events only for parts of itself that are newly visible. This flag is set or cleared by the widget’s author.
Qt.WA_StyleSheet	Indicates that the widget is styled using a style sheet . WA_StyleSheet is set whenever a widget is subject to a style sheet, even if the style sheet did not affect the widget appearance.
Qt.WA_StyleSheetTarget	Indicates that the widget appearance was modified by a style sheet . WA_StyleSheet will also be set. This value was introduced in Qt 5.12.
Qt.WA_TabletTracking	Indicates that the widget has tablet tracking enabled. See tabletTracking .
Qt.WA_TranslucentBackground	Indicates that the widget should have a translucent background, i.e., any non-opaque regions of the widgets will be translucent because the widget will have an alpha channel. Setting this flag causes WA_NoSystemBackground to be set. On Windows the widget also needs the FramelessWindowHint window flag to be set. This flag is set or cleared by the widget’s author. As of Qt 5.0, toggling this attribute after the widget has been shown is not uniformly supported across platforms. When translucent background is desired, set the attribute early when creating the widget, and avoid altering it afterwards.
Qt.WA_UnderMouse	Indicates that the widget is under the mouse cursor. The value is not updated correctly during drag and drop operations. There is also a getter function, underMouse() . This flag is set or cleared by the Qt kernel.
Qt.WA_UpdatesDisabled	Indicates that updates are blocked (including the system background). This flag is set or cleared by the Qt kernel. Warning: This flag must never be set or cleared by the widget’s author.
Qt.WA_WindowModified	Indicates that the window is marked as modified. On some platforms this flag will do nothing, on others (including macOS and Windows) the window will take a modified appearance. This flag is set or cleared by setWindowModified() .
Qt.WA_WindowPropagation	Makes a toplevel window inherit font, palette and locale from its parent.
Qt.WA_MacAlwaysShowToolWindow	On macOS, show the tool window even when the application is not active. By default, all tool windows are hidden when the application is inactive.
Qt.WA_SetLocale	Indicates the locale should be taken into consideration in the widget.
Qt.WA_StyledBackground	Indicates the widget should be drawn using a styled background.
Qt.WA_ShowWithoutActivating	Show the widget without making it active.
Qt.WA_NativeWindow	Indicates that a native window is created for the widget. Enabling this flag will also force a native window for the widget’s ancestors unless Qt::WA_DontCreateNativeAncestors is set.
Qt.WA_DontCreateNativeAncestors	Indicates that the widget’s ancestors are kept non-native even though the widget itself is native.
Qt.WA_X11NetWmWindowTypeDesktop	Adds _NET_WM_WINDOW_TYPE_DESKTOP to the window’s _NET_WM_WINDOW_TYPE X11 window property. See http://standards.freedesktop.org/wm-spec/ for more details. This attribute has no effect on non-X11 platforms.
Qt.WA_X11NetWmWindowTypeDock	Adds _NET_WM_WINDOW_TYPE_DOCK to the window’s _NET_WM_WINDOW_TYPE X11 window property. See http://standards.freedesktop.org/wm-spec/ for more details. This attribute has no effect on non-X11 platforms.
Qt.WA_X11NetWmWindowTypeToolBar	Adds _NET_WM_WINDOW_TYPE_TOOLBAR to the window’s _NET_WM_WINDOW_TYPE X11 window property. See http://standards.freedesktop.org/wm-spec/ for more details. This attribute has no effect on non-X11 platforms. Note: Qt automatically sets this attribute for QToolBar .
Qt.WA_X11NetWmWindowTypeMenu	Adds _NET_WM_WINDOW_TYPE_MENU to the window’s _NET_WM_WINDOW_TYPE X11 window property. See http://standards.freedesktop.org/wm-spec/ for more details. This attribute has no effect on non-X11 platforms. Note: Qt automatically sets this attribute for QMenu when torn-off.
Qt.WA_X11NetWmWindowTypeUtility	Adds _NET_WM_WINDOW_TYPE_UTILITY to the window’s _NET_WM_WINDOW_TYPE X11 window property. See http://standards.freedesktop.org/wm-spec/ for more details. This attribute has no effect on non-X11 platforms. Note: Qt automatically sets this attribute for the Tool window type.
Qt.WA_X11NetWmWindowTypeSplash	Adds _NET_WM_WINDOW_TYPE_SPLASH to the window’s _NET_WM_WINDOW_TYPE X11 window property. See http://standards.freedesktop.org/wm-spec/ for more details. This attribute has no effect on non-X11 platforms. Note: Qt automatically sets this attribute for the SplashScreen window type.
Qt.WA_X11NetWmWindowTypeDialog	Adds _NET_WM_WINDOW_TYPE_DIALOG to the window’s _NET_WM_WINDOW_TYPE X11 window property. See http://standards.freedesktop.org/wm-spec/ for more details. This attribute has no effect on non-X11 platforms. Note: Qt automatically sets this attribute for the Dialog and Sheet window types.
Qt.WA_X11NetWmWindowTypeDropDownMenu	Adds _NET_WM_WINDOW_TYPE_DROPDOWN_MENU to the window’s _NET_WM_WINDOW_TYPE X11 window property. See http://standards.freedesktop.org/wm-spec/ for more details. This attribute has no effect on non-X11 platforms. Note: Qt automatically sets this attribute for QMenu objects added to a QMenuBar .
Qt.WA_X11NetWmWindowTypePopupMenu	Adds _NET_WM_WINDOW_TYPE_POPUP_MENU to the window’s _NET_WM_WINDOW_TYPE X11 window property. See http://standards.freedesktop.org/wm-spec/ for more details. This attribute has no effect on non-X11 platforms. Note: Qt automatically sets this attribute for QMenu .
Qt.WA_X11NetWmWindowTypeToolTip	Adds _NET_WM_WINDOW_TYPE_TOOLTIP to the window’s _NET_WM_WINDOW_TYPE X11 window property. See http://standards.freedesktop.org/wm-spec/ for more details. This attribute has no effect on non-X11 platforms. Note: Qt automatically sets this attribute for the ToolTip window type.
Qt.WA_X11NetWmWindowTypeNotification	Adds _NET_WM_WINDOW_TYPE_NOTIFICATION to the window’s _NET_WM_WINDOW_TYPE X11 window property. See http://standards.freedesktop.org/wm-spec/ for more details. This attribute has no effect on non-X11 platforms.
Qt.WA_X11NetWmWindowTypeCombo	Adds _NET_WM_WINDOW_TYPE_COMBO to the window’s _NET_WM_WINDOW_TYPE X11 window property. See http://standards.freedesktop.org/wm-spec/ for more details. This attribute has no effect on non-X11 platforms. Note: Qt automatically sets this attribute for the QComboBox pop-up.
Qt.WA_X11NetWmWindowTypeDND	Adds _NET_WM_WINDOW_TYPE_DND to the window’s _NET_WM_WINDOW_TYPE X11 window property. See http://standards.freedesktop.org/wm-spec/ for more details. This attribute has no effect on non-X11 platforms. Note: Qt automatically sets this attribute on the feedback widget used during a drag.
Qt.WA_AcceptTouchEvents	Allows touch events (see QTouchEvent ) to be sent to the widget. Must be set on all widgets that can handle touch events. Without this attribute set, events from a touch device will be sent as mouse events.
Qt.WA_TouchPadAcceptSingleTouchEvents	Allows touchpad single touch events to be sent to the widget.
Qt.WA_X11DoNotAcceptFocus	Asks the window manager to not give focus to this top level window. This attribute has no effect on non-X11 platforms.
Qt.WA_AlwaysStackOnTop	Forces QOpenGLWidget and QQuickWidget to be drawn last, on top of other widgets. Ignored for other type of widgets. Setting this attribute breaks the stacking order, but allows having a semi-transparent OpenGL widget with other widgets visible underneath. It is strongly recommended to call update() on the widget’s top-level window after enabling or disabling this attribute.
Qt.WA_ContentsMarginsRespectsSafeArea	A QWidget respects the safe area margins of a window by incorporating the margins into its contents’ margins by default. This means, that a QLayout will use the content area of a widget for its layout, unless the Qt::WA_LayoutOnEntireRect attribute is set. This along with a contents margin of 0 can be used on the actual layout, to allow for example a background image to underlay the status bar and other system areas on an iOS device, while still allowing child widgets of that background to be inset based on the safe area.

PySide6.QtCore.Qt.ApplicationAttribute

This enum describes attributes that change the behavior of application-wide features. These are enabled and disabled using QCoreApplication::setAttribute(), and can be tested for with QCoreApplication::testAttribute().

Constant	Description
Qt.AA_DontShowIconsInMenus	Actions with the Icon property won’t be shown in any menus unless specifically set by the iconVisibleInMenu property. Menus that are currently open or menus already created in the native macOS menubar may not pick up a change in this attribute. Changes in the iconVisibleInMenu property will always be picked up.
Qt.AA_DontShowShortcutsInContextMenus	Actions with the Shortcut property won’t be shown in any shortcut menus unless specifically set by the shortcutVisibleInContextMenu property. This value was added in Qt 5.10, and defaults to the preference reported by the implementation of QPlatformIntegration::styleHint. To override the platform integration, set this attribute after QCoreApplication has been instantiated.
Qt.AA_NativeWindows	Ensures that widgets have native windows.
Qt.AA_DontCreateNativeWidgetSiblings	Ensures that siblings of native widgets stay non-native unless specifically set by the WA_NativeWindow attribute.
Qt.AA_PluginApplication	Indicates that Qt is used to author a plugin. Depending on the operating system, it suppresses specific initializations that do not necessarily make sense in the plugin case. For example on macOS, this includes avoiding loading our nib for the main menu and not taking possession of the native menu bar. Setting this attribute to true will also set the AA_DontUseNativeMenuBar attribute to true. It also disables native event filters. This attribute must be set before QGuiApplication constructed. This value was added in Qt 5.7.
Qt.AA_DontUseNativeMenuBar	All menubars created while this attribute is set to true won’t be used as a native menubar (e.g, the menubar at the top of the main screen on macOS).
Qt.AA_MacDontSwapCtrlAndMeta	Keyboard shortcuts on macOS are typically based on the Command (or Cmd) keyboard modifier, represented by the ⌘ symbol. For example, the ‘Copy’ action is Command+C (⌘+C). To ease cross platform development Qt will by default remap Command to the ControlModifier , to align with other platforms. This allows creating keyboard shortcuts such as “Ctrl+J”, which on macOS will then map to Command+J, as expected by macOS users. The actual Control (or Ctrl) modifier on macOS, represented by ⌃, is mapped to MetaModifier .

When this attribute is true Qt will not do the remapping, and pressing the Command modifier will result in MetaModifier , while pressing the Control modifier will result in ControlModifier .

Note that the StandardKey sequences will always be based on the same modifier (i.e., Copy will be Command+C regardless of the value set), but what is output for toString() will be different.

Constant	Description
Qt.AA_Use96Dpi	Assume the screen has a resolution of 96 DPI rather than using the OS-provided resolution. This will cause font rendering to be consistent in pixels-per-point across devices rather than defining 1 point as 1/72 inch.
Qt.AA_SynthesizeTouchForUnhandledMouseEvents	All mouse events that are not accepted by the application will be translated to touch events instead.
Qt.AA_SynthesizeMouseForUnhandledTouchEvents	All touch events that are not accepted by the application will be translated to left button mouse events instead. This attribute is enabled by default.
Qt.AA_ForceRasterWidgets	Make top-level widgets use pure raster surfaces, and do not support non-native GL-based child widgets.
Qt.AA_UseDesktopOpenGL	Forces the usage of desktop OpenGL (for example, opengl32.dll or libGL.so) on platforms that use dynamic loading of the OpenGL implementation. This attribute must be set before QGuiApplication is constructed. This value was added in Qt 5.3.
Qt.AA_UseOpenGLES	Forces the usage of OpenGL ES 2.0 or higher on platforms that use dynamic loading of the OpenGL implementation. This attribute must be set before QGuiApplication is constructed. This value was added in Qt 5.3.
Qt.AA_UseSoftwareOpenGL	Forces the usage of a software based OpenGL implementation on platforms that use dynamic loading of the OpenGL implementation. This will typically be a patched build of Mesa llvmpipe , providing OpenGL 2.1. The value may have no effect if no such OpenGL implementation is available. The default name of this library is opengl32sw.dll and can be overridden by setting the environment variable QT_OPENGL_DLL. See the platform-specific pages, for instance Qt for Windows , for more information. This attribute must be set before QGuiApplication is constructed. This value was added in Qt 5.4.
Qt.AA_ShareOpenGLContexts	Enables resource sharing between the OpenGL contexts used by classes like QOpenGLWidget and QQuickWidget . This allows sharing OpenGL resources, like textures, between QOpenGLWidget instances that belong to different top-level windows. This attribute must be set before QGuiApplication is constructed. This value was added in Qt 5.4.
Qt.AA_SetPalette	Indicates whether a palette was explicitly set on the QGuiApplication . This value was added in Qt 5.5.
Qt.AA_UseStyleSheetPropagationInWidgetStyles	By default, Qt Style Sheets disable regular QWidget palette and font propagation. When this flag is enabled, font and palette changes propagate as though the user had manually called the corresponding QWidget methods. See The Style Sheet Syntax - Inheritance for more details. This value was added in Qt 5.7.
Qt.AA_DontUseNativeDialogs	All dialogs created while this attribute is set to true won’t use the native dialogs provided by the platform. This value was added in Qt 5.7.
Qt.AA_SynthesizeMouseForUnhandledTabletEvents	All tablet events that are not accepted by the application will be translated to mouse events instead. This attribute is enabled by default. This value was added in Qt 5.7.
Qt.AA_CompressHighFrequencyEvents	Enables compression of certain frequent events. On the X11 windowing system, the default value is true, which means that MouseMove , TouchUpdate , and changes in window size and position will be combined whenever they occur more frequently than the application handles them, so that they don’t accumulate and overwhelm the application later. On Windows 8 and above the default value is also true, but it only applies to touch events. Mouse and window events remain unaffected by this flag. On other platforms, the default is false. (In the future, the compression feature may be implemented across platforms.) You can test the attribute to see whether compression is enabled. If your application needs to handle all events with no compression, you can unset this attribute. Notice that input events from tablet devices will not be compressed. See AA_CompressTabletEvents if you want these to be compressed as well. This value was added in Qt 5.7.
Qt.AA_CompressTabletEvents	Enables compression of input events from tablet devices. Notice that AA_CompressHighFrequencyEvents must be true for events compression to be enabled, and that this flag extends the former to tablet events. Currently supported on the X11 windowing system, Windows 8 and above. The default value is false. This value was added in Qt 5.10.
Qt.AA_DontCheckOpenGLContextThreadAffinity	When making a context current using QOpenGLContext , do not check that the QObject thread affinity of the QOpenGLContext object is the same thread calling makeCurrent() . This value was added in Qt 5.8.
Qt.AA_DisableShaderDiskCache	Disables caching of shader program binaries on disk. By default Qt Quick, QPainter ‘s OpenGL backend, and any application using QOpenGLShaderProgram with one of its addCacheableShaderFromSource overloads will employ a disk-based program binary cache in either the shared or per-process cache storage location, on systems that support glProgramBinary(). In the unlikely event of this being problematic, set this attribute to disable all disk-based caching of shaders.
Qt.AA_DisableSessionManager	Disables the QSessionManager . By default Qt will connect to a running session manager for a GUI application on supported platforms, use of a session manager may be redundant for system services. This attribute must be set before QGuiApplication is constructed. This value was added in 5.14
Qt.AA_DisableNativeVirtualKeyboard	When this attribute is set, the native on-screen virtual keyboard will not be shown automatically when a text input widget gains focus on a system without a physical keyboard. Currently supported on the Windows platform only. This value was added in 5.15

PySide6.QtCore.Qt.ImageConversionFlag

(inherits enum.Flag) The options marked “(default)” are set if no other values from the list are included (since the defaults are zero):

Color/Mono preference (ignored for QBitmap ):

Constant	Description
Qt.AutoColor	(default) - If the image has depth 1 and contains only black and white pixels, the pixmap becomes monochrome.
Qt.ColorOnly	The pixmap is dithered/converted to the native display depth.
Qt.MonoOnly	The pixmap becomes monochrome. If necessary, it is dithered using the chosen dithering algorithm.

Dithering mode preference:

Constant	Description
Qt.DiffuseDither	(default) - A high-quality dither using error diffusion.
Qt.OrderedDither	A faster, ordered dither.
Qt.ThresholdDither	No dithering; closest color is used.

Dithering mode preference for 1-bit alpha masks:

Constant	Description
Qt.ThresholdAlphaDither	(default) - No dithering.
Qt.OrderedAlphaDither	A faster, ordered dither.
Qt.DiffuseAlphaDither	A high-quality dither using error diffusion.

Color matching versus dithering preference:

Constant	Description
Qt.PreferDither	Always dither images when converting to smaller color-spaces.
Qt.AvoidDither	Only dither to indexed formats if the source image uses more different colors than the size of the color table of the destination format.
Qt.AutoDither	(default) - Only dither when down-converting to 1 or 8-bit indexed formats.
Qt.NoOpaqueDetection	Do not check whether the image contains non-opaque pixels. Use this if you know that the image is semi-transparent and you want to avoid the overhead of checking the pixels in the image until a non-opaque pixel is found, or if you want the pixmap to retain an alpha channel for some other reason. If the image has no alpha channel this flag has no effect.
Qt.NoFormatConversion	Don’t do any format conversions on the image. Can be useful when converting a QImage to a QPixmap for a one-time rendering operation for example. Note that a QPixmap not in the preferred format will be much slower as a paint device.

PySide6.QtCore.Qt.BGMode

PySide6.QtCore.Qt.DateFormat

Constant	Description
Qt.TextDate	The default Qt format, which includes the day and month name, the day number in the month, and the year in full. The day and month names will be short names in English (C locale). This effectively uses, for a date, format ddd MMM d yyyy, for a time HH:mm:ss and combines these as ddd MMM d HH:mm:ss yyyy for a date-time, with an optional zone-offset suffix, where relevant. When reading from a string, a fractional part is also recognized on the seconds of a time part, as HH:mm:ss.zzz, and some minor variants on the format may be recognized, for compatibility with earlier versions of Qt and with changes to the format planned for the future. In particular, the zone-offset suffix presently uses GMT[±tzoff] with a tzoff in HH[[:]mm] format (two-digit hour and optional two-digit minutes, with optional colon separator); this shall change to use UTC in place of GMT in a future release of Qt, so the planned UTC format is recognized.
Qt.ISODateWithMs	ISO 8601 extended format: uses yyyy-MM-dd for dates, HH:mm:ss.zzz for times or yyyy-MM-ddTHH:mm:ss.zzz (e.g. 2017-07-24T15:46:29.739) for combined dates and times, optionally with a time-zone suffix (Z for UTC otherwise an offset as ±HH:mm) where appropriate. When parsed, a single space, ' ', may be used in place of the 'T' separator between date and time; no other spacing characters are permitted. This format also accepts HH:mm and plain HH formats for the time part, either of which may include a fractional part, HH:mm.zzz or HH.zzz, applied to the last field present (hour or minute).
Qt.ISODate	ISO 8601 extended format, as for ISODateWithMs, but omitting the milliseconds (.zzz) part when converting to a string. There is no difference when reading from a string: if a fractional part is present on the last time field, either format will accept it.
Qt.RFC2822Date	RFC 2822 , RFC 850 and RFC 1036 format: when converting dates to string form, format dd MMM yyyy is used, for times the format is HH:mm:ss. For combined date and time, these are combined as dd MMM yyyy HH:mm:ss ±tzoff (omitting the optional leading day of the week from the first format recognized). When reading from a string either [ddd,] dd MMM yyyy [HH:mm[:ss]][ ±tzoff] or ddd MMM dd[ HH:mm:ss] yyyy[ ±tzoff] will be recognized for combined dates and times, where tzoff is a timezone offset in HHmm format. Arbitrary spacing may appear before or after the text and any non-empty spacing may replace the spaces in this format. For dates and times separately, the same formats are matched and the unwanted parts are ignored. In particular, note that a time is not recognized without an accompanying date.

Note

For ISODate formats, each y, M and d represents a single digit of the year, month, and day used to specify the date. Each H, m, and s represents a single digit of the hour (up to 24), minute and second used to specify the time. An hour of 24, with zero for all other time fields, is understood as the start of the next day. A .zzz stands for a fractional part suffix on the preceding field, which may be separated from that field either by a comma ',' or the dot '.' shown. Precision beyond milliseconds is accepted but discarded, rounding to the nearest representable millisecond. The presence of a literal T character is used to separate the date and time when both are specified. For the TextDate and RFC2822Date formats, ddd stands for the first three letters of the name of the day of the week and MMM stands for the first three letters of the month name. The names of days and months are always in English (C locale) regardless of user preferences or system settings. The other format characters have the same meaning as for the ISODate format, except that 24 is not accepted as an hour. Parts of a format enclosed in square brackets [...] are optional; the square brackets do not form part of the format. The plus-or-minus character '±' here stands for either sign character, '-' for minus or '+' for plus.

Note

Zone offsets are measured positive to the east of Greenwich, negative to the west, as is usual for UTC-based offset notations (conflicting with some GMT-based zones-names, such as Etc/GMT+3, which use the opposite convention).

PySide6.QtCore.Qt.TimeSpec

Constant	Description
Qt.LocalTime	Local time, controlled by a system time-zone setting.
Qt.UTC	Coordinated Universal Time.
Qt.OffsetFromUTC	An offset in seconds from Coordinated Universal Time.
Qt.TimeZone	A named time zone.

Both LocalTime and TimeZone will take care of transitions, such as the start and end of daylight-saving time. UTC is the standard time relative to which time-zones are usually specified: Greenwich Mean Time has zero offset from it. Neither UTC nor OffsetFromUTC has any transitions.

When specifying a datetime using OffsetFromUTC, the offset from UTC must also be supplied (it is measured in seconds). To specify a datetime using TimeZone, a QTimeZone must be supplied. From Qt 6.5, a QTimeZone can now package a timespec with, where needed, an offset as a lightweight time description, so that passing a QTimeZone now provides a uniform way to use datetime APIs, saving the need to call them differently for different timespecs.

Note

After a change to the system time-zone setting, the behavior of LocalTime-based QDateTime objects created before the change is undefined: QDateTime may have cached data that the change invalidates. (This is not triggered by transitions of the system time-zone.) In long-running processes, updates to the system’s time-zone data (e.g. when politicians change the rules for a zone) may likewise lead to conflicts between the updated time-zone information and data cached by QDateTime objects created before the update, using either LocalTime or TimeZone.

Qt.ScrollBarAlwaysOff	QAbstractScrollArea never shows a scroll bar.
Qt.ScrollBarAlwaysOn	QAbstractScrollArea always shows a scroll bar. This property is ignored on systems with transient scroll bars (e.g., on Mac from version 10.7).

(The modes for the horizontal and vertical scroll bars are independent.)

PySide6.QtCore.Qt.CaseSensitivity

Constant	Description
Qt.CaseInsensitive
Qt.CaseSensitive

PySide6.QtCore.Qt.Corner

Constant	Description
Qt.TopLeftCorner	The top-left corner of the rectangle.
Qt.TopRightCorner	The top-right corner of the rectangle.
Qt.BottomLeftCorner	The bottom-left corner of the rectangle.
Qt.BottomRightCorner	The bottom-right corner of the rectangle.

Qt.LeftEdge	The left edge of the rectangle.
Qt.RightEdge	The right edge of the rectangle.
Qt.BottomEdge	The bottom edge of the rectangle.

PySide6.QtCore.Qt.ConnectionType

This enum describes the types of connection that can be used between signals and slots. In particular, it determines whether a particular signal is delivered to a slot immediately or queued for delivery at a later time.

Constant	Description
Qt.AutoConnection	(Default) If the receiver lives in the thread that emits the signal, Qt::DirectConnection is used. Otherwise, Qt::QueuedConnection is used. The connection type is determined when the signal is emitted.
Qt.DirectConnection	The slot is invoked immediately when the signal is emitted. The slot is executed in the signalling thread.
Qt.QueuedConnection	The slot is invoked when control returns to the event loop of the receiver’s thread. The slot is executed in the receiver’s thread.
Qt.BlockingQueuedConnection	Same as Qt::QueuedConnection, except that the signalling thread blocks until the slot returns. This connection must not be used if the receiver lives in the signalling thread, or else the application will deadlock.
Qt.UniqueConnection	This is a flag that can be combined with any one of the above connection types, using a bitwise OR. When Qt::UniqueConnection is set, connect() will fail if the connection already exists (i.e. if the same signal is already connected to the same slot for the same pair of objects). This flag was introduced in Qt 4.6.
Qt.SingleShotConnection	This is a flag that can be combined with any one of the above connection types, using a bitwise OR. When Qt::SingleShotConnection is set, the slot is going to be called only once; the connection will be automatically broken when the signal is emitted. This flag was introduced in Qt 6.0.

With queued connections, the parameters must be of types that are known to Qt’s meta-object system, because Qt needs to copy the arguments to store them in an event behind the scenes. If you try to use a queued connection and get the error message:

QObject::connect: Cannot queue arguments of type 'MyType'

Call qRegisterMetaType() to register the data type before you establish the connection.

When using signals and slots with multiple threads, see Signals and Slots Across Threads .

PySide6.QtCore.Qt.ShortcutContext

For a Shortcut event to occur, the shortcut’s key sequence must be entered by the user in a context where the shortcut is active. The possible contexts are these:

Constant	Description
Qt.WidgetShortcut	The shortcut is active when its parent widget has focus.
Qt.WidgetWithChildrenShortcut	The shortcut is active when its parent widget, or any of its children has focus. Children which are top-level widgets, except pop-ups, are not affected by this shortcut context.
Qt.WindowShortcut	The shortcut is active when its parent widget is a logical subwidget of the active top-level window.
Qt.ApplicationShortcut	The shortcut is active when one of the applications windows are active.

PySide6.QtCore.Qt.FillRule

Specifies which method should be used to fill the paths and polygons.

Constant	Description
Qt.OddEvenFill	Specifies that the region is filled using the odd even fill rule. With this rule, we determine whether a point is inside the shape by using the following method. Draw a horizontal line from the point to a location outside the shape, and count the number of intersections. If the number of intersections is an odd number, the point is inside the shape. This mode is the default.
Qt.WindingFill	Specifies that the region is filled using the non zero winding rule. With this rule, we determine whether a point is inside the shape by using the following method. Draw a horizontal line from the point to a location outside the shape. Determine whether the direction of the line at each intersection point is up or down. The winding number is determined by summing the direction of each intersection. If the number is non zero, the point is inside the shape. This fill mode can also in most cases be considered as the intersection of closed shapes.

PySide6.QtCore.Qt.MaskMode

This enum specifies the behavior of the createMaskFromColor() and QImage::createMaskFromColor() functions.

Constant	Description
Qt.MaskInColor	Creates a mask where all pixels matching the given color are opaque.

PySide6.QtCore.Qt.ItemSelectionMode

This enum is used in QGraphicsItem , QGraphicsScene and QGraphicsView to specify how items are selected, or how to determine if shapes and items collide.

Constant	Description
Qt.ContainsItemShape	The output list contains only items whose shape is fully contained inside the selection area. Items that intersect with the area’s outline are not included.
Qt.IntersectsItemShape	The output list contains both items whose shape is fully contained inside the selection area, and items that intersect with the area’s outline. This is a common mode for rubber band selection.
Qt.ContainsItemBoundingRect	The output list contains only items whose bounding rectangle is fully contained inside the selection area. Items that intersect with the area’s outline are not included.
Qt.IntersectsItemBoundingRect	The output list contains both items whose bounding rectangle is fully contained inside the selection area, and items that intersect with the area’s outline. This method is commonly used for determining areas that need redrawing.

PySide6.QtCore.Qt.EnterKeyType

This can be used to alter the appearance of the Return key on an on-screen keyboard.

Note

Not all of these values are supported on all platforms. For unsupported values the default key will be used instead.

Constant	Description
Qt.EnterKeyDefault	The default Enter key. This can either be a button closing the keyboard, or a Return button causing a new line in case of a multi-line input field.
Qt.EnterKeyReturn	Show a Return button that inserts a new line. The keyboard will not close when this button is pressed.
Qt.EnterKeyDone	Show a “Done” button. The keyboard will close when this button is pressed.

Qt.ItemIsUserCheckable	It can be checked or unchecked by the user.
Qt.ItemIsEnabled	The user can interact with the item.
Qt.ItemIsAutoTristate	The item’s state depends on the state of its children. This enables automatic management of the state of parent items in QTreeWidget (checked if all children are checked, unchecked if all children are unchecked, or partially checked if only some children are checked).
Qt.ItemNeverHasChildren	The item never has child items. This is used for optimization purposes only.
Qt.ItemIsUserTristate	The user can cycle through three separate states. This value was added in Qt 5.5.

Note that checkable items need to be given both a suitable set of flags and an initial state, indicating whether the item is checked or not. This is handled automatically for model/view components, but needs to be explicitly set for instances of QListWidgetItem , QTableWidgetItem , and QTreeWidgetItem .

Note that it is undefined behavior to reimplement hasChildren to return true for an index if that index has the Qt::ItemNeverHasChildren flag set.

The timer type indicates how accurate a timer can be.

Constant	Description
Qt.PreciseTimer	Precise timers try to keep millisecond accuracy
Qt.CoarseTimer	Coarse timers try to keep accuracy within 5% of the desired interval
Qt.VeryCoarseTimer	Very coarse timers only keep full second accuracy

On UNIX (including Linux, macOS, and iOS), Qt will keep millisecond accuracy for Qt::PreciseTimer. For Qt::CoarseTimer, the interval will be adjusted up to 5% to align the timer with other timers that are expected to fire at or around the same time. The objective is to make most timers wake up at the same time, thereby reducing CPU wakeups and power consumption.

On Windows, Qt will use Windows’s Multimedia timer facility (if available) for Qt::PreciseTimer and normal Windows timers for Qt::CoarseTimer and Qt::VeryCoarseTimer.

On all platforms, the interval for Qt::VeryCoarseTimer is rounded to the nearest full second (e.g. an interval of 23500ms will be rounded to 24000ms, and 20300ms to 20000ms).

PySide6.QtCore.Qt.ScrollPhase

This enum describes the phase of scrolling.

Constant	Description
Qt.NoScrollPhase	The input device doesn’t support scroll phase. This value was introduced in Qt 5.7.
Qt.ScrollBegin	Scrolling is about to begin, but the scrolling distance did not yet change.
Qt.ScrollUpdate	The scrolling distance has changed (default).
Qt.ScrollEnd	Scrolling has ended, and the scrolling distance did not change anymore.
Qt.ScrollMomentum	The user no longer touches the input device, but scrolling continues due to scroll momentum. This value was introduced in Qt 5.12.

PySide6.QtCore.Qt.MouseEventSource

This enum describes the source of a mouse event and can be useful to determine if the event is an artificial mouse event originating from another device such as a touchscreen.

Constant	Description
Qt.MouseEventNotSynthesized	The most common value. On platforms where such information is available this value indicates that the event was generated in response to a genuine mouse event in the system.
Qt.MouseEventSynthesizedBySystem	Indicates that the mouse event was synthesized from a touch event by the platform.
Qt.MouseEventSynthesizedByQt	Indicates that the mouse event was synthesized from an unhandled touch event by Qt.
Qt.MouseEventSynthesizedByApplication	Indicates that the mouse event was synthesized by the application. This allows distinguishing application-generated mouse events from the ones that are coming from the system or are synthesized by Qt. This value was introduced in Qt 5.6

PySide6.QtCore.Qt.PermissionStatus

This enum describes the possible statuses of a permissions.

Constant	Description
Qt.PermissionStatus.Undetermined	The permission status is not yet known. Permission should be requested via requestPermission() to determine the actual status. This status will never be the result of requesting a permission.
Qt.PermissionStatus.Granted	The user has explicitly granted the application the permission, or the permission is known to not require user authorization on the given platform.
Qt.PermissionStatus.Denied	The user has explicitly denied the application the requested permission, or the permission is known to not be accessible or applicable to applications on the given platform.

Note

On Android, there is no Undetermined status by the platform’s APIs. Thus, if a permission is denied for an app, checkPermission() returns Undetermined by default until requestPermission() is called. After that checkPermission() reports a non Undetermined status.

static PySide6.QtCore.Qt.beginPropertyUpdateGroup()

Marks the beginning of a property update group. Inside this group, changing a property does neither immediately update any dependent properties nor does it trigger change notifications. Those are instead deferred until the group is ended by a call to endPropertyUpdateGroup .

Groups can be nested. In that case, the deferral ends only after the outermost group has been ended.

Note

Change notifications are only send after all property values affected by the group have been updated to their new values. This allows re-establishing a class invariant if multiple properties need to be updated, preventing any external observer from noticing an inconsistent state.
