I'm using a hold browser and i think its scrollbar is stealing a shortcut to a menu item i have assigned to ctrl-end. How can I prevent this? subclass the scrollbar? Or is it legit to have a handle and a callback for the same widget i.e. the browser?

Yes, you can subclass and have a callback attached to the widget. If you want to "filter" shortcuts (that can't be changed in the base class you would subclass and define your handle() where you'd test for the event in question and return 0 *before* you call the handle() method of the base class, for instance

myclass::handle(int e) {
if (e == FL_SHORTCUT && Fl::key() == FL_END)
return 0;
return baseclass::handle();
}

In this case the FL_END keypress would be propagated to any other widget that "wants" it.

Note: I can't tell if your assumption is correct, but if it is something like the code above should help.
