QT - window on top

Question

'WindowStaysOnTopHint' doesn't work for widget 'ww', why?

Dialog w;
widget ww;
ww.setWindowFlags(Qt::WindowStaysOnTopHint);
ww.setWindowFlags(Qt::FramelessWindowHint);
ww.setFixedSize(206,206);
w.show();
ww.show();

Answer 1

Because you are replacing it with Qt::FramelessWindowHint .

If you want both:

ww.setWindowFlags(Qt::WindowStaysOnTopHint | Qt::FramelessWindowHint);
