[patch] avoid complete redraws for child widget updates
Hello, here comes a patch that avoids complete redrawing if only a child widget (button or form input) requests redrawing. I don't really like the fact, that fltk widgets are sometimes drawn via Group::draw() and sometimes via theLayout->expose(), but this is already the case without my patch, so I just leave it as it is for now. In the long run, I would propose to add a mechanism similar to fltk DAMAGE_CHILD to dw. To test go to google and type in some text. Cheers, Johannes

Committed.

Yes. AFAIR we talked about this with Sebastian. IIRC he also didn't like much the mixed approach, and if he found a simpler way to do it, it'd be changed. The complex button stuff, and the fltk embedding could be avoided by re-implementing those in dw, but it looks like overkill.

If you find a simpler/better way, it's more than welcomed. -- Cheers Jorge.-
