Struct qt_widgets::QGraphicsSceneResizeEvent

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

The QGraphicsSceneResizeEvent class provides events for widget resizing in the graphics view framework.

C++ class: QGraphicsSceneResizeEvent.

C++ documentation:

The QGraphicsSceneResizeEvent class provides events for widget resizing in the graphics view framework.

A QGraphicsWidget sends itself a QGraphicsSceneResizeEvent immediately when its geometry changes.

It's similar to QResizeEvent, but its sizes, oldSize() and newSize(), use QSizeF instead of QSize.

Methods

impl QGraphicsSceneResizeEvent

pub unsafe fn new() -> CppBox<QGraphicsSceneResizeEvent>

Constructs a QGraphicsSceneResizeEvent.

Calls C++ function: [constructor] void QGraphicsSceneResizeEvent::QGraphicsSceneResizeEvent().

C++ documentation:

Constructs a QGraphicsSceneResizeEvent.

pub unsafe fn new_size(&self) -> CppBox<QSizeF>

Returns the new size (i.e., the current size).

Calls C++ function: QSizeF QGraphicsSceneResizeEvent::newSize() const.

C++ documentation:

Returns the new size (i.e., the current size).

See also oldSize() and QGraphicsWidget::resize().

pub unsafe fn old_size(&self) -> CppBox<QSizeF>

Returns the old size (i.e., the size immediately before the widget was resized).

Calls C++ function: QSizeF QGraphicsSceneResizeEvent::oldSize() const.

C++ documentation:

Returns the old size (i.e., the size immediately before the widget was resized).

See also newSize() and QGraphicsWidget::resize().

pub unsafe fn set_new_size(&self, size: impl CastInto<Ref<QSizeF>>)

Calls C++ function: void QGraphicsSceneResizeEvent::setNewSize(const QSizeF& size).

pub unsafe fn set_old_size(&self, size: impl CastInto<Ref<QSizeF>>)

Calls C++ function: void QGraphicsSceneResizeEvent::setOldSize(const QSizeF& size).

Methods from Deref<Target = QGraphicsSceneEvent>

pub unsafe fn set_widget(&self, widget: impl CastInto<Ptr<QWidget>>)

Calls C++ function: void QGraphicsSceneEvent::setWidget(QWidget* widget).

pub unsafe fn widget(&self) -> QPtr<QWidget>

Returns the widget where the event originated, or 0 if the event originates from another application.

Calls C++ function: QWidget* QGraphicsSceneEvent::widget() const.

C++ documentation:

Returns the widget where the event originated, or 0 if the event originates from another application.

Trait Implementations
