Yes, a better place to ask this sort of question, for sure. > I'd like to know if it's a bug that the attached program needs to > explicitly call redraw() in the callback.

I guess I'd hazard "feature" rather than bug, but I guess it is a close call. This looks like the sort of thing (deleting a widget in its own callback) that requires the use of ::delete_widget(...) in fltk-1.x, but that should not be necessary in fltk-2. I guess an STR would not go amiss for this. In the meantime, the redraw seems to have the desired effect, so at least the workaround is easy!
