QQnxRasterBackingStore (QWindow *window) | |
~QQnxRasterBackingStore () | |
QPaintDevice * | paintDevice () override |
Implement this function to return the appropriate paint device. | |
void | flush (QWindow *window, const QRegion ®ion, const QPoint &offset) override |
Flushes the given region from the specified window. | |
void | resize (const QSize &size, const QRegion &staticContents) override |

Scrolls the given area dx pixels to the right and dy downward; both dx and dy may be negative. | |
void | beginPaint (const QRegion ®ion) override |
This function is called before painting onto the surface begins, with the region in which the painting will occur. | |
void | endPaint () override |
This function is called after painting onto the surface has ended. | |
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 FlushResult | rhiFlush (QWindow *window, qreal sourceDevicePixelRatio, const QRegion ®ion, const QPoint &offset, QPlatformTextureList *textures, bool translucentBackground) |
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. | |

overridevirtual |
Flushes the given region from the specified 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.
