Struct qt_gui::QExposeEvent

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

The QExposeEvent class contains event parameters for expose events.

C++ class: QExposeEvent.

C++ documentation:

The QExposeEvent class contains event parameters for expose events.

Expose events are sent to windows when an area of the window is invalidated or window visibility in the windowing system changes.

The event handler QWindow::exposeEvent() receives expose events.

Methods

impl QExposeEvent

pub unsafe fn copy_from(
    &self,
    other: impl CastInto<Ref<QExposeEvent>>
) -> Ref<QExposeEvent>

pub unsafe fn new(rgn: impl CastInto<Ref<QRegion>>) -> CppBox<QExposeEvent>

Constructs an expose event for the given exposeRegion which must be in local coordinates.

Calls C++ function: [constructor] void QExposeEvent::QExposeEvent(const QRegion& rgn).
