Hi, I've been using QDialog as my main window, but it has just a close button in the upper right corner, and no minimize and no maximize button, which I want. And it closes down when I press escape, which I don't want it to do. So I figured that QDialog is probably not the widget I want. So which widget do I want to use? I tried QMainWindow, but then no of the widgets I added to it showed up, and the window turned white inside (instead of the light grey color it usually gets). Did I maybe use the QMainWindow wrong? It really sounds like it could be the widget I want, although I'm not sure about it.
