Then, a message box will appear and ask for your confirmation. Tick Delete file permanently and press the OK button.

  3. After that, open up your project file (.pro) and add the OpenGL module to your project by adding an opengl keyword behind QT +=, like so:

    LIBS += -lopengl32 -lglu32
  5. Then, open up mainwindow.h and remove several things from it:

    #ifndef MAINWINDOW_H
    #define MAINWINDOW_H
    #include <QMainWindow...
