Yes, you can, but you must take care that you don't call the
callback twice. That's why I'm not a fan of calling the base
class's handle() unconditionally before doing one's own checks.
See also what Greg wrote about the reasons to call it on FL_RELEASE.
Given the code above, Fl_Browser::handle() would call the
callback on FL_RELEASE, and your code would call it on FL_PUSH
as well.
