Performance in hiding/showing widgets

Aha, thanks. I think I know what to do now. Time to dig deeper into QT I guess.
Maybe I should have asked how to override the QTreeView behaviour in the first place :-)

QT = QuickTime(R) by Apple
Qt = Quasar toolkit (or other legendary explanation of "Q toolkit" name) by Trolltech.

Just a quick note to tell the people about my next steps/

Apparently VMWare is free nowadays, so I installed Linux and did some speed tests. Although the screen driver is very slow, the app with 250 buttons acts very fast under Linux. However when I try my complete program the widget drawing is even slower than on Windows. So as Wysota told me, it is not a good idea to draw too many widgets.

I have tried extending the behaviour of the QTreeView class by having items span more than one column, but failed miserably. Though I had a lot of fun trying. And some nice effects.

So, in the end I thought it would be better to check if the snapshots for Qt 4.3 had the desired "span" featured and they did. Compilation under Linux was easy, Windows with Visual C++ was a bit annoying, but I now have the desired behaviour out of the box. Yeah. Thanks for all the help.

The point was that people tend to mix them up. This forum focuses on Qt, not on QT. Which are two different things..

obviously, why would we discuss QT in here?

We wouldn't, but many people write "QT" when referring to "Qt", so sometimes we tend to point out that difference.
