As I mentioned the background goes black when I try to set it to transparent ot semi transparent.
I tried this:
@
QPalette P;
P.setBrush(QPalette::Background , Qt::transparent);
setPalette(P);
@and this:
@
this->setStyleSheet("QMainWindow {background:transparent}");
@also some other things like using rgba.

the only valid way to do this that worked with me is:
@
setWindowOpacity(qreal)
@but the problem with this is that I'm using widget that their parents is my mainwindow which I want it to be transparent , so if I set my main window to semi transparent using setWindowOpacity() it'll effect all of my widgets.
