Detailed Description

The QGraphicsSceneWheelEvent class provides wheel events in the graphics view framework.

The QGraphicsSceneWheelEvent class provides wheel events in the graphics view framework.

Since
4.2

\inmodule QtWidgets

\l{QWheelEvent}{QWheelEvent}s received by a QGraphicsView are translated into QGraphicsSceneWheelEvents; it translates the QWheelEvent::globalPos() into item, scene, and screen coordinates (pos(), scenePos(), and screenPos()).

Constructor & Destructor Documentation

◆ QGraphicsSceneWheelEvent()

QGraphicsSceneWheelEvent::QGraphicsSceneWheelEvent ( Type  type = None)
explicit

Definition at line 734 of file qgraphicssceneevent.cpp.

◆ ~QGraphicsSceneWheelEvent()

QGraphicsSceneWheelEvent::~QGraphicsSceneWheelEvent ( )

Destroys the QGraphicsSceneWheelEvent.

Definition at line 742 of file qgraphicssceneevent.cpp.

Member Function Documentation

◆ buttons()

Qt::MouseButtons QGraphicsSceneWheelEvent::buttons ( ) const

Returns the mouse buttons that were pressed when the wheel event occurred.

See also
modifiers()

Definition at line 814 of file qgraphicssceneevent.cpp.

Here is the caller graph for this function:

◆ delta()

int QGraphicsSceneWheelEvent::delta ( ) const

Returns the distance that the wheel is rotated, in eighths (1/8s) of a degree. A positive value indicates that the wheel was rotated forwards away from the user; a negative value indicates that the wheel was rotated backwards toward the user.

Most mouse types work in steps of 15 degrees, in which case the delta value is a multiple of 120 (== 15 * 8).

Definition at line 859 of file qgraphicssceneevent.cpp.

Here is the caller graph for this function:

◆ isInverted()

bool QGraphicsSceneWheelEvent::isInverted ( ) const

Returns whether the delta values delivered with the event are inverted.

Since
6.2

Definition at line 944 of file qgraphicssceneevent.cpp.

◆ modifiers()

Qt::KeyboardModifiers QGraphicsSceneWheelEvent::modifiers ( ) const

Returns the keyboard modifiers that were active when the wheel event occurred.

See also
buttons()

Definition at line 835 of file qgraphicssceneevent.cpp.

Here is the caller graph for this function:

◆ orientation()

Qt::Orientation QGraphicsSceneWheelEvent::orientation ( ) const

Returns the wheel orientation.

Definition at line 877 of file qgraphicssceneevent.cpp.

Here is the caller graph for this function:

◆ phase()

Qt::ScrollPhase QGraphicsSceneWheelEvent::phase ( ) const
Since
6.2

Returns the scrolling phase of this wheel event.

See also
QWheelEvent::phase

Definition at line 899 of file qgraphicssceneevent.cpp.

◆ pixelDelta()

QPoint QGraphicsSceneWheelEvent::pixelDelta ( ) const
Since
6.2

Returns the scrolling distance in pixels on screen. This value is provided on platforms that support high-resolution pixel-based delta values, such as \macos. The value should be used directly to scroll content on screen.

See also
QWheelEvent::pixelDelta

Definition at line 924 of file qgraphicssceneevent.cpp.

Here is the caller graph for this function:

◆ pos()

QPointF QGraphicsSceneWheelEvent::pos ( ) const

Returns the position of the cursor in item coordinates when the wheel event occurred.

See also
scenePos(), screenPos()

Definition at line 752 of file qgraphicssceneevent.cpp.

Here is the caller graph for this function:

◆ scenePos()

QPointF QGraphicsSceneWheelEvent::scenePos ( ) const

Returns the position of the cursor in scene coordinates when the wheel event occurred.

See also
pos(), screenPos()

Definition at line 773 of file qgraphicssceneevent.cpp.

◆ screenPos()

QPoint QGraphicsSceneWheelEvent::screenPos ( ) const

Returns the position of the cursor in screen coordinates when the wheel event occurred.

See also
pos(), scenePos()

Definition at line 794 of file qgraphicssceneevent.cpp.

◆ setButtons()

void QGraphicsSceneWheelEvent::setButtons ( Qt::MouseButtons  buttons)
