Not exactly sure what it is you are asking about, but as a general note, I find
that it is often instructive to create a little example of what I'm trying to
do using fluid, then look at athe code it generated for insights into how to
use the widgets...
e.g. (assuming this fluid file does what you want, of course!) this fluid file..
------------
# data file for the Fltk User Interface Designer (fluid)
version 1.0300
header_name {.h}
code_name {.cxx}
decl {\#include <stdio.h>} {selected private local
}
Function {} {open
} {
Fl_Window main_win {
label {Test Window} open
xywh {640 311 356 231} type Double visible
} {
Fl_Menu_Bar menu_bar {open
xywh {0 0 356 20}
} {
Submenu menu1 {
label {A Menu} open
xywh {0 0 62 20}
} {
MenuItem item1 {
label {Item 1}
callback {puts("Item 1");
fflush(stdout);}
xywh {0 0 30 20} type Toggle
}
MenuItem item2 {
label {Item 2}
callback {puts("Item 2");
fflush(stdout);}
xywh {10 10 30 20} type Toggle
}
MenuItem item3 {
label {Item 3}
callback {puts("Item 3");
fflush(stdout);}
xywh {20 20 30 20} type Toggle
}
MenuItem item4 {
label {Item 4}
callback {puts("Item 4");
fflush(stdout);}
xywh {30 30 30 20} type Toggle
}
}
}
}
}
------------
Creates the following C++ output:
------------

#include "menu-chk.h"
#include <stdio.h>
Fl_Double_Window *main_win=(Fl_Double_Window *)0;
Fl_Menu_Bar *menu_bar=(Fl_Menu_Bar *)0;
static void cb_item1(Fl_Menu_*, void*) {
puts("Item 1");
fflush(stdout);
}
static void cb_item2(Fl_Menu_*, void*) {
puts("Item 2");
fflush(stdout);
}
static void cb_item3(Fl_Menu_*, void*) {
puts("Item 3");
fflush(stdout);
}
static void cb_item4(Fl_Menu_*, void*) {
puts("Item 4");
fflush(stdout);
}
Fl_Menu_Item menu_menu_bar[] = {
{"A Menu", 0, 0, 0, 64, FL_NORMAL_LABEL, 0, 14, 0},
{"Item 1", 0, (Fl_Callback*)cb_item1, 0, 2, FL_NORMAL_LABEL, 0, 14, 0},
{"Item 2", 0, (Fl_Callback*)cb_item2, 0, 2, FL_NORMAL_LABEL, 0, 14, 0},

{"Item 4", 0, (Fl_Callback*)cb_item4, 0, 2, FL_NORMAL_LABEL, 0, 14, 0},
{0,0,0,0,0,0,0,0,0},
{0,0,0,0,0,0,0,0,0}
};
int main(int argc, char **argv) {
{ main_win = new Fl_Double_Window(356, 231, "Test Window");
{ menu_bar = new Fl_Menu_Bar(0, 0, 356, 20);
menu_bar->menu(menu_menu_bar);
} // Fl_Menu_Bar* menu_bar
main_win->end();
} // Fl_Double_Window* main_win
main_win->show(argc, argv);
return Fl::run();
}

Does that help at all?
