Member Function Documentation

ensureActiveTarget() [1/2]

void QOpenGLWindowPaintDevice::ensureActiveTarget ( )

overridevirtual

This virtual method is provided as a callback to allow re-binding a target frame buffer object or context when different QOpenGLPaintDevice instances are issuing draw calls alternately.

\l{QPainter::beginNativePainting()}{beginNativePainting()} will also trigger this method.

The default implementation does nothing.

Reimplemented from QOpenGLPaintDevice.
