How can I hold up a event in fltk? not the add_callback()!!example :
in a Fl_input widget, when a key pressed, don't let it displayed in widget ,but ought
to be  handle by mine, and I don't want editing the handle_key() method in Fl_input.cxx.
how can I do??

I think the fltk 's event handle is hard , did I need fltk's widget plus nano-X's event
process?
