In the Qt::dialog Window Flag description one can read: "decorated as a dialog (i.e., typically no maximize or minimize buttons in the title bar)"

Any idea why this does not work (at least under Linux)?

I can get either the whole Title Bar (with minimize/maximize buttons) or nothing.

How to eliminate the minimize/maximize buttons in Dialog?
(Arithmetical & with negation of according flags does not work)

thanks for your help
