That should not work well for CAD applications.

We have a large drawing area, where we draw objects using cairo drawing
functions. That are not GTK widgets!

Ardour does the same thing. Except that our objects (all drawn using a custom cairo canvas) do have enter/leave handling. Pressing delete while the mouse pointer is inside an object deletes that object.

(*) the current release version uses gnomecanvas, but the next major release will use our new cairo canvas; the principle remains the same either way.
