[Qt-interest] QDialog behavior

[Tony Thompson]

After a bit more experimenting, I know why I added those flags on my
dialog.  And it gets even more weird...

I would like a dialog with a plain title bar.  No window close buttons,
no system menu, no "?" button on Windows.  I have an icon specified for
my dialog so I only want the icon and the title of the dialog to show.

If I specify those flags:
windows - no icon but plain title bar (no buttons) with title (pretty
close)
Linux - no title bar or window frame (my original issue)
Mac - title bar with icon and title, grayed out system buttons (min, max
close) (not bad)

If I don't specify those flags:
windows - title bar with icon (and system menu), title, "?" what's this
button, and close button
Linux - title bar with icon (and system menu), title, close button
Mac - title bar with icon and title (PERFECT!)

I can't seem to find a set of flags that will give me what I want on all
platforms.  The only one that really works the way I want is on the Mac
without the flags.  Is there some combination of window flags that will
give me what I want on all platforms?  Or do I have to set flags in an
OS specific way to get the dialog to behave on each platform?  Any hints
on how I might set those flags even if it is OS specific?

I can provide screen shots for each of my cases if it would help but I
didn't feel it beneficial to flood the list with them.
