Hello there,

I have a window with some widgets on it. I want to catch mouse click events in the window but not on children. Although a callback has been set to the window but it was never triggered. I look into FLTK source and see that Fl_Window uses Fl_Group::handle() to handle events. In the section of FL_PUSH, it just passes events to each of its children and do no callback.

I don't want to change the FLTK source. Is there any way I can handle events outside of child widgets?

Thanks.

an event will only go to its children if the handle event returns zero, indicating it was not handled. http://www.fltk.org/documentation.ph...ng.html#handle

So try overloading the Fl_Window handle() function like this:
