Hi! I built opencv with qt support (I used http://qt-project.org/downloads version 5.0 beta 2) and I didn't get any error when compiling, but when I try to create a namedwindow using CV_GUI_EXPANDED flag I only get a normal window without toolbar. Also, I can't create a trackbar targeting a NULL window. Do I have to use qt 4.8.3 when compiling opencv? I am using Visual Studio 2010 and 2012, CMake and opencv 2.4.3.
