Member Function Documentation

◆ doneCurrent()

void QGLXContext::doneCurrent ( )

overridevirtual

Implements QPlatformOpenGLContext.

Definition at line 532 of file qglxintegration.cpp.

◆ format()

QSurfaceFormat QGLXContext::format ( ) const

overridevirtual

Implements QPlatformOpenGLContext.

Definition at line 565 of file qglxintegration.cpp.

◆ getProcAddress()

QFunctionPointer QGLXContext::getProcAddress ( const char * procName )

overridevirtual

Reimplement in subclass to allow dynamic querying of OpenGL symbols.

As opposed to e.g. the wglGetProcAddress function on Windows, Qt expects this methods to be able to return valid function pointers even for standard OpenGL symbols.

Implements QPlatformOpenGLContext.
