Transparent QWidget on Viewport

[vux]

Is it posible to draw qwidget with transparent background above maya 3d viewport?

[Justin Israel]

Whenever I try to parent a widget to the M3dView, I can't see it. I
assume Maya is handling the parenting action explicitly in a custom
way.
The only thing I can suggest is having a floating widget that tracks
the position of the M3dView widget.

Maybe someone else has had better luck than me.

I need for example QLabel with text but without background on viewport. I meen that widget is child of viewport. My attempts were unsuccessful.

The background allways fill with noise of older refreshes of viewport :(

I've been wanting to set output cmdScrollFieldReporter to viewport. Imagine that you work in viewport and watch a couple of lines of current output.

I was trying to do something similar ( drawing a non-square transparent bg qt widget as a child of the viewport ) and hit exactly the same issue that you describe. Sadly I never found a solution and couldn't spend masses of time looking at it, so I can't really help but if you do find a solution I'd certainly like to hear it!

I've seen other people post about this issue as well. I think maya uses the window id to draw directly to the widget in OpenGL. So the solution would probably involve drawing to it in a lower level way.

The best I have thought about for now is having an event filter with a widget just parented to the main window, that watches the viewport resize/move/etc events and stays tacked on.

I'm having similar issues while trying to display a png file with transparent background, maya turns it black(the background). Since the last post form this thread was in 2012, has there been any success with this?

Thanks!
