You'd want to use: Fl::event_clicks(); in your handle()
function to detect multi-click operations.
Here's a compilable example showing how it's used.
This counts the number of multi-clicks in the window area,
and prints a message on the tty with the count:
#include <FL/Fl.H>
#include <FL/Fl_Window.H>
//
// Example: how to count clicks on a widget 03/07/12
//
class MyWindow : public Fl_Window {
public:
MyWindow(int W,int H,const char *L=0) : Fl_Window(W,H,L) {
}
int handle(int e) {
switch (e) {
case FL_PUSH:
printf("Number of clicks: %d\n", (Fl::event_clicks()+1));
break;
}
return(Fl_Window::handle(e));
}
};
int main() {
MyWindow win(300,200,"Counts clicks in window");
win.show();
return(Fl::run());
}
