And I tagged it "solved" as well :)

If this answers your question, please update the thread title prepending [solved] so other forum users may know it's all good :)

The log says:

bq.
This ensures that the possible window flag combinations are respected
where possible in Cocoa.

Thanks for the clarification!

Looking at the sources, I can't say it's a regression, in fact it looks like it's 5.1 that didn't have the correct behavior.

Qt::CustomizeWindowHint means "turn off the default window title hints" From there you can customize it to your liking (title, button etc.) Something that it seem you could not do in 5.1

I got a simple test case :) I built it with 5.2.1 (stable) and the problem occurs. If I build it with 5.1.0, no problem (the window title stays put).

@#include <QApplication>
#include <QDialog>
int main(int argc, char *argv[])
{
QApplication a(argc, argv);

QDialog *dialog = new QDialog();

dialog->show(); // appears with window title

dialog->hide();

dialog->setWindowFlags(
Qt::Dialog |
Qt::CustomizeWindowHint |
Qt::WindowStaysOnTopHint);

dialog->show(); // in 5.1, window title is there but not in 5.2.1 (or 5.2.0)

return a.exec();
}
@

That should reproduce the problem... please let me know if it doesn't or if there's anything else I can do.

Thanks!

Yes, a test case would be very good
