Detailed Description#
The class is designed as a common super class for widgets like QSpinBox
, QDoubleSpinBox
and QDateTimeEdit
Here are the main properties of the class:
text
: The text that is displayed in theQAbstractSpinBox
.alignment : The alignment of the text in the
QAbstractSpinBox
.
wrapping
: Whether theQAbstractSpinBox
wraps from the minimum value to the maximum value and vice versa.
QAbstractSpinBox
provides a virtual stepBy()
function that is called whenever the user triggers a step. This function takes an integer value to signify how many steps were taken. E.g. Pressing Key_Down
will trigger a call to stepBy
(-1).
When the user triggers a step whilst holding the ControlModifier
, QAbstractSpinBox
steps by 10 instead of making a single step. This step modifier affects wheel events, key events and interaction with the spinbox buttons. Note that on macOS, Control corresponds to the Command key.
Since Qt 5.12, SH_SpinBox_StepModifier
can be used to select which KeyboardModifier
increases the step rate. NoModifier
disables this feature.
QAbstractSpinBox
also provide a virtual function stepEnabled()
to determine whether stepping up/down is allowed at any point. This function returns a bitset of StepEnabled
.
- class PySide6.QtWidgets.QAbstractSpinBox([parent=None])#
- Parameters:
parent –
PySide6.QtWidgets.QWidget
Constructs an abstract spinbox with the given parent
with default wrapping
, and alignment properties.
Note
Properties can be used directly when from __feature__ import true_property
is used or via accessor functions otherwise.
- property PᅟySide6.QtWidgets.QAbstractSpinBox.accelerated: bool#
This property holds whether the spin box will accelerate the frequency of the steps when pressing the step Up/Down buttons..
If enabled the spin box will increase/decrease the value faster the longer you hold the button down.
- Access functions:
setAccelerated
(on)
- property PᅟySide6.QtWidgets.QAbstractSpinBox.acceptableInput: bool#
This property holds whether the input satisfies the current validation.
See also
- Access functions:
- property PᅟySide6.QtWidgets.QAbstractSpinBox.alignment: Alignment#
This property holds the alignment of the spin box.
Possible Values are AlignLeft
, AlignRight
, and AlignHCenter
.
By default, the alignment is AlignLeft
Attempting to set the alignment to an illegal flag combination does nothing.

Alignment
- Access functions:

()setAlignment
(flag)
- property PᅟySide6.QtWidgets.QAbstractSpinBox.buttonSymbols: ButtonSymbols#
This property holds the current button symbol mode.
The possible values can be either UpDownArrows
or PlusMinus
. The default is UpDownArrows
.
Note that some styles might render PlusMinus
and UpDownArrows
identically.

ButtonSymbols
- Access functions:
setButtonSymbols
(bs)
- property PᅟySide6.QtWidgets.QAbstractSpinBox.correctionMode: CorrectionMode#
This property holds the mode to correct an Intermediate
value if editing finishes.
The default mode is CorrectToPreviousValue
.

- Access functions:
setCorrectionMode
(cm)
- property PᅟySide6.QtWidgets.QAbstractSpinBox.frame: bool#
This property holds whether the spin box draws itself with a frame.
If enabled (the default) the spin box draws itself inside a frame, otherwise the spin box draws itself without any frame.
- property PᅟySide6.QtWidgets.QAbstractSpinBox.keyboardTracking: bool#
This property holds whether keyboard tracking is enabled for the spinbox..
If keyboard tracking is enabled (the default), the spinbox emits the valueChanged() and textChanged() signals while the new value is being entered from the keyboard.
E.g. when the user enters the value 600 by typing 6, 0, and 0, the spinbox emits 3 signals with the values 6, 60, and 600 respectively.
If keyboard tracking is disabled, the spinbox doesn’t emit the valueChanged() and textChanged() signals while typing. It emits the signals later, when the return key is pressed, when keyboard focus is lost, or when other spinbox functionality is used, e.g. pressing an arrow key.
- Access functions:
setKeyboardTracking
(kt)
- property PᅟySide6.QtWidgets.QAbstractSpinBox.readOnly: bool#
This property holds whether the spin box is read only..
In read-only mode, the user can still copy the text to the clipboard, or drag and drop the text; but cannot edit it.
The QLineEdit
in the QAbstractSpinBox
does not show a cursor in read-only mode.

- property PᅟySide6.QtWidgets.QAbstractSpinBox.showGroupSeparator: bool#
This property holds whether a thousands separator is enabled. By default this property is false..
- Access functions:
setGroupSeparatorShown
(shown)
- property PᅟySide6.QtWidgets.QAbstractSpinBox.specialValueText: str#
Warning
This section contains snippets that were automatically translated from C++ to Python and may contain errors.
This property holds the special-value text.
If set, the spin box will display this text instead of a numeric value whenever the current value is equal to minimum(). Typical use is to indicate that this choice has a special (default) meaning.
For example, if your spin box allows the user to choose a scale factor (or zoom level) for displaying an image, and your application is able to automatically choose one that will enable the image to fit completely within the display window, you can set up the spin box like this:
zoomSpinBox = QSpinBox() zoomSpinBox.setRange(0, 1000) zoomSpinBox.setSingleStep(10) zoomSpinBox.setSuffix("%") zoomSpinBox.setSpecialValueText(tr("Automatic")) zoomSpinBox.setValue(100)
The user will then be able to choose a scale from 1% to 1000% or select “Auto” to leave it up to the application to choose. Your code must then interpret the spin box value of 0 as a request from the user to scale the image to fit inside the window.
All values are displayed with the prefix and suffix (if set), except for the special value, which only shows the special value text. This special text is passed in the textChanged()
signal that passes a QString
.
To turn off the special-value text display, call this function with an empty string. The default is no special-value text, i.e. the numeric value is shown as usual.
If no special-value text is set, specialValueText() returns an empty string.
- Access functions:
setSpecialValueText
(txt)
- property PᅟySide6.QtWidgets.QAbstractSpinBox.text: str#
This property holds the spin box’s text, including any prefix and suffix.
There is no default text.
- Access functions:
text
()
- property PᅟySide6.QtWidgets.QAbstractSpinBox.wrapping: bool#
Warning
This section contains snippets that were automatically translated from C++ to Python and may contain errors.
This property holds whether the spin box is circular..
If wrapping is true stepping up from maximum() value will take you to the minimum() value and vice versa. Wrapping only make sense if you have minimum() and maximum() values set.

- PySide6.QtWidgets.QAbstractSpinBox.stepBy(steps)#
- Parameters:
steps – int
Virtual function that is called whenever the user triggers a step. The steps
parameter indicates how many steps were taken. For example, pressing Qt::Key_Down
will trigger a call to stepBy(-1)
, whereas pressing Qt::Key_PageUp
will trigger a call to stepBy(10)
.
If you subclass QAbstractSpinBox
you must reimplement this function. Note that this function is called even if the resulting value will be outside the bounds of minimum and maximum. It’s this function’s job to handle these situations.

- PySide6.QtWidgets.QAbstractSpinBox.stepDown()#
Steps down by one linestep Calling this slot is analogous to calling stepBy
(-1);
- PySide6.QtWidgets.QAbstractSpinBox.stepEnabled()#
- Return type:
StepEnabled
Virtual function that determines whether stepping up and down is legal at any given time.
The up arrow will be painted as disabled unless (stepEnabled() & StepUpEnabled
) != 0.
The default implementation will return ( StepUpEnabled
| StepDownEnabled
) if wrapping is turned on. Else it will return StepDownEnabled
if value is > minimum() or’ed with StepUpEnabled
if value < maximum().
If you subclass QAbstractSpinBox
you will need to reimplement this function.
