Re: embedding gtk widgets in a buffer

[Richard M Stallman]

    Just to clarify, the placeholder widgets in non-selected windows, would
    be placeholders, not live buttons. They wont become live again until
    that window is selected again.

I am not sure what a placeholder widget does.
Would it work to click on one of these widgets?
It is supposed to work.

    I had in mind getting the widgets to temporarily render into offscreen
    bitmaps.

If you can do that, it should be easy for Emacs to handle displaying
parts of that bitmap (or pixmap?) onto various parts of the screen as needed,
and translating clicks on any of those parts to give them to the widget.
The widget could be associated with the buffer
and not have any specific location on the screen.
