I can imagine two problems with your code:
(1) the docs (cited by you above) state:
"You must call Fl_Window::show(argc, argv) for the icon to be used.
The Fl_Window::show() method does not bind the icon to the window."
Change this first to see if it works (you need to change your main()
function arguments if you don't have argc and argv included).
Note: I'm not sure that this is really needed, since I saw it work w/o
argc and argv, too (FLTK 1.3). Maybe the docs are not correct...
(2) you must add the resource file to your project, but I can't tell
you how to do this with VC2008 :-( . To test if it worked, you could
try to change your code like this:
char *my_icon = (char *)LoadIcon(fl_display, MAKEINTRESOURCE(IDI_ICON));
// print/debug here, what LoadIcon returned (must not be 0)
mainWindow->icon(my_icon);
mainWindow->show(argc,argv);
