Struct qt_widgets::QGraphicsSceneWheelEvent

#[repr(C)]pub struct QGraphicsSceneWheelEvent { /* fields omitted */ }

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

C++ class: QGraphicsSceneWheelEvent.

C++ documentation:

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

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

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

Methods

impl QGraphicsSceneWheelEvent

pub unsafe fn buttons(&self) -> QFlags<MouseButton>

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

Calls C++ function: QFlags<Qt::MouseButton> QGraphicsSceneWheelEvent::buttons() const.

C++ documentation:

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

See also modifiers().

pub unsafe fn delta(&self) -> c_int

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.

Calls C++ function: int QGraphicsSceneWheelEvent::delta() const.

C++ documentation:

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).

pub unsafe fn modifiers(&self) -> QFlags<KeyboardModifier>

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

Calls C++ function: QFlags<Qt::KeyboardModifier> QGraphicsSceneWheelEvent::modifiers() const.

C++ documentation:

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