|QExposeEvent(const QRegion &exposeRegion)|
|const QRegion &||region() const|
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 exposure in the windowing system changes.
A Window with a client area that is completely covered by another window, or is otherwise not visible may be considered obscured by Qt and may in such cases not receive expose events.
The event handler QWindow::exposeEvent() receives expose events.
Constructs an expose event for the given exposeRegion which must be in local coordinates.
Returns the window area that has been exposed. The region is given in local coordinates.
