Good morning,
I’m implementing a heads up display (a “HUD”) that’s overlaid on a 3d rendered scene. I’d like to be able to display and interact with Qt widgets in the overlaid HUD. I need some advice/help to get moving again.
I’ve been able to create a bitmap that shared between a QImage and the 3d code. I can render controls to the bitmap using the render() method on the controls and they display nicely in the HUD. I have to manually manage and repaint these controls and there’s no way to use a mouse to manipulate them.
My first attempt:
I created a custom QWindowSurface that renders to my shared bitmap. QImage is a valid QPaintDevice.
Then I create a tree of controls that use that surface. This doesn’t seem to work.
The methods in the Surface are never called.
Any suggestions?
I’d like to be able to send mouse events to these controls so I can drag them around on the HUD.
I’d like them to manage their own repainting.
I’d like something Qt 5 compatible as I probably will switch
Might QGraphicsScene work for this? Can you add QWidgets to a QGraphicsScene?
Environment:
Qt 4.7
Mingw-dtm
Thanks
