[Qt-interest] How to draw transparent widgets on canvas?

[Jason H]

This is nothing more than just drawing the items, without drawing the background. I would probably use a widget, for all the signals it can emit and embed that. Just don't bother to draw the background. Then it is only a matter of setting the z-order. You can do this explicily, or you can make the map a child of the view control. Just make sure you don't clip children.

Goolge map's zoom-in/zoom-out, navagation widget.
It's transparent and on top of the map.

Any pointer is appreciated.
