Can't get title bar to disappear from widget

[wysota]

What if you don't want a full-screen widget?

Then you don't call QWidget::showFullScreen().

Wouldn't the flags method I suggested be a more general solution that would work regardless of window size?

There are many different "what ifs" we could discuss. If you have a frameless window, you can't even move it or close it so what's the point of having it this way?
