Please see the section on handling events, eg:
http://fltk.org/doc-1.3/events.html
Under the section on "Keyboard Events":
"To receive FL_KEYBOARD events you must also respond to the
FL_FOCUS and FL_UNFOCUS events."
So to see clicks on the keyboard (such as Shift, Arrow keys, etc):
int handle(int e) {
int ret = Fl_Browser::handle(e); // REQUIRED
switch (e) {
case FL_FOCUS:
case FL_UNFOCUS:
return(1); // Return 1 for FOCUS/UNFOCUS to
get keyboard events
case FL_KEYBOARD:
cout << "keyboard" << endl;
return(1);
}
return(ret);
}
For clicking/selecting items in Fl_Browser, you'd normally want
to set a callback() for the widget to invoke a function to handle
clicking on items.
But if you want to get mouse click events in an Fl_Browser, you can
flesh out the above:
int handle(int e) {
int ret = Fl_Browser::handle(e);
switch (e) {
case FL_FOCUS:
case FL_UNFOCUS:
return(1);
case FL_KEYBOARD:
cout << "test" << endl;
break;
case FL_PUSH: // MOUSE CLICK PUSH
cout << "push" << endl;
ret = 1;
break;
case FL_RELEASE: // MOUSE CLICK RELEASE
cout << "release" << endl;
ret = 1;
break;
}
return(ret);
}
Here's a working program showing all the above:
#include <iostream>
#include <FL/Fl_Window.H>
#include <FL/Fl_Browser.H>
using namespace std;
class flbrw : public Fl_Browser {
public:
flbrw(int X,int Y,int W,int H,const char*L=0):Fl_Browser(X,Y,W,H,L) {
add("one");
add("two");
add("three");
type(FL_MULTI_BROWSER);
}
int handle(int e) {
int ret = Fl_Browser::handle(e);
switch (e) {
case FL_FOCUS:
case FL_UNFOCUS:
return(1);
case FL_KEYBOARD:
cout << "test" << endl;
break;
case FL_PUSH:
cout << "push" << endl;
ret = 1;
break;
case FL_RELEASE:
cout << "release" << endl;
ret = 1;
break;
}
return(ret);
}
};
int main() {
Fl_Window *win = new Fl_Window(300,200);
flbrw *brow = new flbrw(10,10,300-20,200-20);
win->end();
win->show();
return(Fl::run());
}
