Detailed Description

Implementation of an OpenGL-based viewer in a Qt Environment.

It requests a MousePosition as input and provides a FrameBuffer as output.

◆ setCacheInfoHandler() [1/4]

void Wizt::QGLViewer::setCacheInfoHandler ( const WeakPtr< qVCacheInfo > & ci )

overridevirtual

Install a callback object that is called whenever there are changes in the OpenGL render cache.

The object specified here is supposed to overload the virtual setCacheInfo() function. This one is called whenever there might be changes in the OpenGL cache usage. Note that this callback function is likely to be called from a subthread and therefore MUST NOT do any Qt GUI calls. It may however set its values into some list queue to be read later by the QViewer widget implementation.
