[Qt-interest] X button does not close modeless dialog

[Malyushytsky, Alex]

Sorry I missed this helpful message first ( my e-mail client put it in separated thread for some reason).
It looks like that explicitly adding the  Qt::WindowCloseButtonHint helps and dialog works as intended.

It is weird that without Qt::WindowMinimizeButtonHint it does too and used to work with QT 4.4.3 just fine.
But adding Qt::WindowCloseButtonHint seems fixes the problem.

Thanks for help,
     Alex

When I build and run your code on my Linux system (Kubuntu 9.04, Qt
4.5.1, kde 4.1.4), no close button appears on the title bar.
Furthermore, in the system menu, Close is disabled.

If I change your window flags to include Qt::WindowCloseButtonHint,
the close button then appears and works correctly. I suggest you try
this.
