Can a QT window be completely styled, including the menu bar when running on Windows 7 or Vista?

Question

I noticed that the sample apps from QT show their menu bar as opaque, and with a color that doesn't match any of the styling on the window. It seems as if the windows being created by QT when running on Vista or Windows 7 don't pick up the translucency that are no the mainstay of the new Windows look and feel. Is there a way to override this in QT, or even have a custom painted menu?

Answer 1

On Windows 7 there is a special flag that activates the "Glass" Look&Feel:

From what I see, only the Qt::WA_TranslucentBackground flag is involved.

Answer 2

All of my Qt applications look native on Vista/Win7, including the "glass" frame. This is all by default.

I must admit I don't know where you got this idea that they don't. Here's what the Browser demo that comes with Qt looks like on my Win7 machine.

I can't see anything wrong with it.
