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