Member Function Documentation

◆ beginPaint()

void QtWaylandClient::QWaylandShmBackingStore::beginPaint ( const QRegion & )
overridevirtual

This function is called before painting onto the surface begins, with the region in which the painting will occur.

See also
endPaint(), paintDevice()

Reimplemented from QPlatformBackingStore.

Definition at line 200 of file qwaylandshmbackingstore.cpp.

◆ contentSurface()

QImage * QtWaylandClient::QWaylandShmBackingStore::contentSurface ( ) const

Definition at line 454 of file qwaylandshmbackingstore.cpp.

◆ endPaint()

void QtWaylandClient::QWaylandShmBackingStore::endPaint ( )
overridevirtual

This function is called after painting onto the surface has ended.

See also
beginPaint(), paintDevice()

Reimplemented from QPlatformBackingStore.

Definition at line 222 of file qwaylandshmbackingstore.cpp.

◆ entireSurface()

QImage * QtWaylandClient::QWaylandShmBackingStore::entireSurface ( ) const

Definition at line 449 of file qwaylandshmbackingstore.cpp.

◆ finalizeBackBuffer()

void QtWaylandClient::QWaylandShmBackingStore::finalizeBackBuffer ( )

Definition at line 418 of file qwaylandshmbackingstore.cpp.

◆ flush()

void QtWaylandClient::QWaylandShmBackingStore::flush ( QWindow * window,
const QRegion & region,
const QPoint & offset )
overridevirtual

Flushes the given region from the specified window.

Note
region is relative to the window which may not be top-level in case window corresponds to a native child widget. offset is the position of the native child relative to the top-level window.

Unlike rhiFlush(), this function's default implementation does nothing. It is expected that subclasses provide a platform-specific (non-QRhi-based) implementation, if applicable on the given platform.
