Well, I wasn't going to say anything ("If you don’ know how to answer it,
please don’t chime in, thanks.")
In my experience, Qt doesn't maintain a good notion of a window's size until
it's shown. But you are guaranteed a Resize event as the window is being shown,
so if you can manage it, you need to handle the Resize event and do your
polishing and layouting there.
In fact, I had for a while a function called ShowAndHideInvisibly(); the
important part of it was like this:
> getQWidget()->setAttribute(Qt::WA_DontShowOnScreen, true);
> WMshow();
> WMhide();
> getQWidget()->setAttribute(Qt::WA_DontShowOnScreen, false);
Maybe that helps. Setting the attribute prevents the screen flash.
