Description

I've compiled OpenCV with QT and OpenGL support from SVN r7339 and cvSetOpenGlCallback not working.
OpenGL support is said enable in the terminal, but an exception is thrown.

With samples/cpp/Qt_sample/main.cpp, output is:

init done 
opengl support available 
OpenCV Error: No OpenGL support (Window doesn't support OpenGL) in setOpenGlDrawCallback, file [..]/OpenCV-SVN/opencv/modules/highgui/src/window_QT.cpp, line 2419
terminate called after throwing an instance of 'cv::Exception'
  what():  [..]/OpenCV-SVN/opencv/modules/highgui/src/window_QT.cpp:2419: error: (-218) Window doesn't support OpenGL in function setOpenGlDrawCallback

Moreover, I can't see the control panel, (even with only a trackbar and/or a button) and displayOverlay and displayStatusBar don't work with a delay of 0.
