QOpenGLMultiGroupSharedResource Class Reference

The QOpenGLMultiGroupSharedResource keeps track of a shared resource that might be needed from multiple contexts, like a glyph cache or gradient cache. One instance of the object is created for each group when necessary. The shared resource instance should have a constructor that takes a QOpenGLContext *. To get an instance for a given context one calls T *QOpenGLMultiGroupSharedResourcevalue<T>(context), where T is a sub-class of QOpenGLSharedResource. \inmodule QtGui. More...

Detailed Description

The QOpenGLMultiGroupSharedResource keeps track of a shared resource that might be needed from multiple contexts, like a glyph cache or gradient cache. One instance of the object is created for each group when necessary. The shared resource instance should have a constructor that takes a QOpenGLContext *. To get an instance for a given context one calls T *QOpenGLMultiGroupSharedResourcevalue<T>(context), where T is a sub-class of QOpenGLSharedResource. \inmodule QtGui.
