If you have an Fl_Choice widget, and pop up its menu, you
can dismiss the menu sub-window by clicking anywhere at
all, so it seems fltk can handle it somehow.
Here's another example. Without the sub-window, grab()
makes all the events visible, as expected. Compare it to
the original.
#include <FL/Fl.H>
#include <FL/Fl_Double_Window.H>
#include <iostream>
class SubWindow : public Fl_Double_Window {
public:
SubWindow(int w, int h, char const* label = 0)
: Fl_Double_Window(w, h, label)
{
end();
}
int handle(int event)
{
if(event == FL_KEYDOWN && Fl::event_key() == FL_Escape) {
exit(0);
}
if(event == FL_PUSH) {
std::cout << "PUSH\n";
}
return Fl_Window::handle(event);
}
};
int main()
{
SubWindow sub(200, 200, "Sub");
sub.show();
Fl::grab(&sub);
return Fl::run();
}
