Public Member Functions inherited from QPlatformBackingStore
 QPlatformBackingStore (QWindow *window)
 Constructs an empty surface for the given top-level window.
virtual ~QPlatformBackingStore ()
 Destroys this surface.
QWindow * window () const
 Returns a pointer to the top-level window associated with this surface.
QBackingStore * backingStore () const
 Returns a pointer to the backing store associated with this surface.
virtual QPaintDevice * paintDevice ()=0
 Implement this function to return the appropriate paint device.
virtual void flush (QWindow *window, const QRegion &region, const QPoint &offset)
 Flushes the given region from the specified window.
virtual FlushResult rhiFlush (QWindow *window, qreal sourceDevicePixelRatio, const QRegion &region, const QPoint &offset, QPlatformTextureList *textures, bool translucentBackground, qreal sourceTransformFactor=0)
 Flushes the given region from the specified window, and compositing it with the specified textures list.
virtual QImage toImage () const
 Implemented in subclasses to return the content of the backingstore as a QImage.
virtual QRhiTexture * toTexture (QRhiResourceUpdateBatch *resourceUpdates, const QRegion &dirtyRegion, TextureFlags *flags) const
 May be reimplemented in subclasses to return the content of the backingstore as an QRhiTexture.
virtual QPlatformGraphicsBuffer * graphicsBuffer () const
 Accessor for a backingstores graphics buffer abstraction.
virtual void resize (const QSize &size, const QRegion &staticContents)=0
virtual bool scroll (const QRegion &area, int dx, int dy)
 Scrolls the given area dx pixels to the right and dy downward; both dx and dy may be negative.
virtual void beginPaint (const QRegion &)
 This function is called before painting onto the surface begins, with the region in which the painting will occur.
virtual void endPaint ()
 This function is called after painting onto the surface has ended.
void createRhi (QWindow *window, QPlatformBackingStoreRhiConfig config)
QRhi * rhi (QWindow *window) const
void surfaceAboutToBeDestroyed ()
void graphicsDeviceReportedLost (QWindow *window)
