Many thanks for the detailed response...

I am aware of how to put transparent objects on the canvas, but what I'm looking for is a way to make the canvas itself (which, now that I think about it, means the canvas and the Mainwindow) transparent. In other words, if you open a window with a transparent background and no window decoration, you'd see... nothing. I want the graphical equivalent of a piece of plate glass, so that I can "paint" control elements on it, and have it pop up such that the control elements appear to overlay whatever is on the screen.

Now, a Menu widget lets you pop up Menu buttons that can be made to appear near the cursor location, so maybe what I'm really looking for is a custom widget derived from the Menu widget. Hmmmm....
