Transparent view with opaque scene and items
Message 1 in thread
Hi!
I have a QGraphicsView with scene and items. Is there any way to set
transparency to that view so as items remains opaque?
Thanks in advance.

Two possibilities:
1) No ideas from any of us
2) We don't really understand what you're asking
I'm in 2).

Ok, another example. I have a widget and push button on it. Button is
child of widget. I want to set widget semitransparent, but button have
to remain full opaque.

Hi Anton,
Since responding earlier, I have found Qt::WA_NoSystemBackground. It seems
to be what you are looking for. But I haven't tested it. Please let me know
whether it works for GraphicsView.
Sometimes searching in assistant doesn't find anything useful. I find that
searching for the OPPOSITE can give extra hits - in this case "opaque"
instead of "transparent".
Hope that helps,
Tony Rietwyk

Hi Tony,
Thank you for answer, but Qt::WA_NoSystemBackground not works for
QGraphicsView - background remains white.
