Struct qt_widgets::QGestureEvent

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

The QGestureEvent class provides the description of triggered gestures.

C++ class: QGestureEvent.

C++ documentation:

The QGestureEvent class provides the description of triggered gestures.

The QGestureEvent class contains a list of gestures, which can be obtained using the gestures() function.

The gestures are either active or canceled. A list of those that are currently being executed can be obtained using the activeGestures() function. A list of those which were previously active and have been canceled can be accessed using the canceledGestures() function. A gesture might be canceled if the current window loses focus, for example, or because of a timeout, or for other reasons.

If the event handler does not accept the event by calling the generic QEvent::accept() function, all individual QGesture object that were not accepted and in the Qt::GestureStarted state will be propagated up the parent widget chain until a widget accepts them individually, by calling QGestureEvent::accept() for each of them, or an event filter consumes the event.

Methods

impl QGestureEvent

pub unsafe fn accept_q_gesture(&self, arg1: impl CastInto<Ptr<QGesture>>)

Sets the accept flag of the given gesture object, the equivalent of calling setAccepted(gesture, true).

Calls C++ function: void QGestureEvent::accept(QGesture* arg1).

C++ documentation:

C++ documentation:

The QGestureEvent class provides the description of triggered gestures.

The QGestureEvent class contains a list of gestures, which can be obtained using the gestures() function.

The gestures are either active or canceled. A list of those that are currently being executed can be obtained using the activeGestures() function. A list of those which were previously active and have been canceled can be accessed using the canceledGestures() function. A gesture might be canceled if the current window loses focus, for example, or because of a timeout, or for other reasons.

If the event handler does not accept the event by calling the generic QEvent::accept() function, all individual QGesture object that were not accepted and in the Qt::GestureStarted state will be propagated up the parent widget chain until a widget accepts them individually, by calling QGestureEvent::accept() for each of them, or an event filter consumes the event.

pub unsafe fn gesture(&self, type_: GestureType) -> QPtr<QGesture>

Returns a gesture object by type.

pub unsafe fn ignore_q_gesture(&self, arg1: impl CastInto<Ptr<QGesture>>)

Clears the accept flag parameter of the given gesture object, the equivalent of calling setAccepted(gesture, false).

Calls C++ function: void QGestureEvent::ignore(QGesture* arg1).

C++ documentation:

Clears the accept flag parameter of the given gesture object, the equivalent of calling setAccepted(gesture, false).

Clearing the accept flag indicates that the event receiver does not want the gesture. Unwanted gestures may be propagated to the parent widget.

See also QGestureEvent::accept().

pub unsafe fn ignore_gesture_type(&self, arg1: GestureType)

Clears the accept flag parameter of the given gestureType, the equivalent of calling setAccepted(gesture, false).

Calls C++ function: void QGestureEvent::ignore(Qt::GestureType arg1).

C++ documentation:

Clears the accept flag parameter of the given gestureType, the equivalent of calling setAccepted(gesture, false).

Clearing the accept flag indicates that the event receiver does not want the gesture. Unwanted gestures may be propgated to the parent widget.

pub unsafe fn is_accepted_q_gesture(
    &self,
    arg1: impl CastInto<Ptr<QGesture>>
) -> bool

Returns true if the gesture is accepted; otherwise returns false.

Calls C++ function: bool QGestureEvent::isAccepted(QGesture* arg1) const.

C++ documentation:

Returns true if the gesture is accepted; otherwise returns false.

pub unsafe fn is_accepted_gesture_type(&self, arg1: GestureType) -> bool

Returns true if the gesture of type gestureType is accepted; otherwise returns false.

Calls C++ function: bool QGestureEvent::isAccepted(Qt::GestureType arg1) const.

C++ documentation:

Returns true if the gesture of type gestureType is accepted; otherwise returns false.

pub unsafe fn map_to_graphics_scene(
    &self,
    gesture_point: impl CastInto<Ref<QPointF>>
) -> CppBox<QPointF>

Returns the scene-local coordinates if the gesturePoint is inside a graphics view.

Calls C++ function: QPointF QGestureEvent::mapToGraphicsScene(const QPointF& gesturePoint) const.

C++ documentation:

Returns the scene-local coordinates if the gesturePoint is inside a graphics view.

This functional might be useful when the gesture event is delivered to a QGraphicsObject to translate a point in screen coordinates to scene-local coordinates.

See also QPointF::isNull().

pub unsafe fn new(
    gestures: impl CastInto<Ref<QListOfQGesture>>
) -> CppBox<QGestureEvent>
