I recently downloaded and built qt 4.7.4 locally, but there is one problem that I have encountered since using it. I will not get the look of Windows 7. I have not had this problem since 4.6.3. This is what my designer.exe looks like:

I keep getting this view, although I tried to open the application with the following commands:
designer.exe -style windowsxp designer.exe -style windowsvista
I tried to open the application using the CDE and Plastique styles, and those that will be applied to the application.
This look is also preserved with my own Qt GUI projects. Any help or ideas are appreciated.
Edit:
My Qt configuration is as follows:
-opensource -platform win32-g++ -qt-sql-sqlite -no-qt3support -no-3dnow -no-phonon -no-multimedia -no-audio-backend -no-webkit -no-native-gestures -no-qmake
