Member Function Documentation

◆ addref() [1/2]

void QQuickPixmapData::addref ( )

Definition at line 1473 of file qquickpixmapcache.cpp.

◆ addref() [2/2]

void QQuickPixmapData::addref ( )

◆ addToCache() [1/2]

void QQuickPixmapData::addToCache ( )

Add this to the QQuickPixmapCache singleton.

Note
The actual image will end up in QQuickPixmapData::textureFactory. At the time addToCache() is called, it's generally not yet loaded; so the qCDebug() below cannot say how much data we're committing to storing. (On the other hand, removeFromCache() can tell.) QQuickTextureFactory is an abstraction for image data. See QQuickDefaultTextureFactory for example: it stores a QImage directly. Other QQuickTextureFactory subclasses store data in other ways.
