Detailed Description

The QPlatformSurfaceEvent class is used to notify about native platform surface events. \inmodule QtGui.

Since
5.5

Platform window events are synchronously sent to windows and offscreen surfaces when their underlying native surfaces are created or are about to be destroyed.

Applications can respond to these events to know when the underlying platform surface exists.

Definition at line 591 of file qevent.h.

Member Enumeration Documentation

◆ SurfaceEventType

enum QPlatformSurfaceEvent::SurfaceEventType

This enum describes the type of platform surface event. The possible types are:

\value SurfaceCreated The underlying native surface has been created \value SurfaceAboutToBeDestroyed The underlying native surface will be destroyed immediately after this event

The SurfaceAboutToBeDestroyed event type is useful as a means of stopping rendering to a platform window before it is destroyed.
