i would like to have a QGraphicsView serve as a HUD over an assumedly openGL Maya modelPanel..
i am able to get my "overLay" QGraphicsView to be translucent when its over normal maya QT interface elements. but when it overlaps the openGL modelPanel, one cannot see the 3D view through the QGraphicsview background. (i have a great image demonstrating this.. no way to attach images here?) how i'm doig it so far: basically i just setColor in the palette of gView.viewPort to (QPalette.Base, Qt.transparent), then, gView.setAttribute(Qt.WA_TranslucentBackground,True) make sure the graphicsView is the central widget of a window.. and pow! ..the background of the QGraphicsView is transparent to all maya interface (save openGL modelPanel) ..but any QGrpahicsItems in the View are opaque, and have all the wonderful utility of the QGraphics framework. big problem though.... whenever this QGraphicsView "overlay" is over a modelPanel, partially or in whole, the overlap with the panel appears black and the graphicsItems leave artifacts (streaks) when you move them around over this area. the view grid or any geometry are not there, just blackness. the Maya modelPanel is not a QGLWidget, (as far as i can tell).. so it is not a simple matter of using QGL classes and functions to composite the two together. one approach might be for me to find a way to openGL render the Maya scene graph myself in a QGL widget in essence, creating my own Qt modelPanel. but that sounds like a long hard road because i would have to mimic all of maya's user interactions with the3D elements depicted in the scene. another approach might be for me to somehow grab snapshots of the maya gl render output as they happen and draw them as the QGraphicsScene background. but that sounds like it could be slow, and i have no idea yet how to intercept the output of a modelPanel viewport in such a way as to get streaming pixamaps into the background of a graphics scene. what i would love is if there is a way to have my "overlay" QgraphicsScene background demonstrate transparency over this maya modelPanel in a totally Maya agnostic way. much the same way that "window.setWindowOpacity(0.2)" does, but with the ability to have opaque items in the graphicsScene -- http://groups.google.com/group/python_inside_maya
