Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property acceptedᅟ: bool¶

Specifies if the mouse wheel event has been accepted

Access functions:

isAccepted()
setAccepted()

property angleDeltaᅟ: QPoint¶

Specifies The change wheel angle of the mouse wheel event

Access functions:

angleDelta()

property buttonsᅟ: int¶

Specifies the button if present in the mouse wheel event

Access functions:

buttons()

property modifiersᅟ: Qt3DInput.QWheelEvent.Modifiers¶

Specifies if any modifiers were applied to the mouse wheel event

Access functions:

modifiers()

property xᅟ: int¶

Specifies The X coordinate of the mouse wheel event

Access functions:

x()

property yᅟ: int¶

Specifies The Y coordinate of the mouse wheel event

Access functions:

__init__(e)¶

Parameters:: e – QWheelEvent

Constructs a new QWheelEvent instance from the QWheelEvent e.

angleDelta()¶

Return type:: QPoint

Returns the distance that the wheel is rotated, in eighths of a degree. A positive value indicates that the wheel was rotated forward (away from the user), a negative value indicates the wheel was rotated backward (toward the user).

Getter of property angleDeltaᅟ .

buttons()¶

Return type:: int

Returns a bitfield to be used to check for mouse buttons that may be accompanying the wheel event.

Getter of property buttonsᅟ .

isAccepted()¶

Return type:: bool

Returns whether the event was accepted.

Getter of property acceptedᅟ .

modifiers()¶

Return type:: Modifiers

Returns the keyboard modifiers that may be accompanying the wheel event.

Getter of property modifiersᅟ .

setAccepted(accepted)¶

Parameters:: accepted – bool

Sets the event as accepted if accepted is true.

Note

When an event is accepted, it will prevent further propagation to other listeners.
