Glib answer: yes.
Better answer: See the menubar_add sample in the examples folder.
Worked example:
/* fl_open_uri demo */
// fltk-config --compile uri_example.cxx
#include <FL/Fl.H>
#include <FL/Fl_Double_Window.H>
#include <FL/Fl_Button.H>
#include <FL/filename.H> // fl_open_uri()
#include <FL/fl_draw.H> // fl_cursor
static Fl_Double_Window *main_win = (Fl_Double_Window *)0;
static Fl_Button *quit_bt = (Fl_Button *)0;
class uri_button: public Fl_Button {
int handle(int e);
public:
uri_button(int x, int y, int w, int h, const char *l = 0) :
Fl_Button
(x, y, w, h, l) {}
};
int uri_button::handle(int e) {
int result = Fl_Button::handle(e);
switch(e) {
case FL_ENTER:
fl_cursor(FL_CURSOR_HAND);
return 1;
case FL_LEAVE:
fl_cursor(FL_CURSOR_DEFAULT);
return 1;
default:
return result;
}
} // uri_button::handle
static uri_button *uri_bt = (uri_button *)0;
static void cb_uri_bt(Fl_Button*, void*) {
fl_open_uri("http://google.com/";);
}
static void cb_quit_bt(Fl_Button*, void*) {
main_win->hide();
}
int main(int argc, char **argv) {
main_win = new Fl_Double_Window(326, 246, "URI test window");
main_win->begin();
uri_bt = new uri_button(100, 75, 105, 45, "Click Me!");
uri_bt->box(FL_FLAT_BOX);
uri_bt->labelsize(20);
uri_bt->labelcolor(FL_BLUE);
uri_bt->callback((Fl_Callback*)cb_uri_bt);
uri_bt->clear_visible_focus();
quit_bt = new Fl_Button(257, 212, 64, 27, "Quit");
quit_bt->callback((Fl_Callback*)cb_quit_bt);
main_win->end();
main_win->show(argc, argv);
return Fl::run();
}
