OK - outcomes...
Didn't need to do anything clever in the end; just a bit of a nasty hack
instead!
Turns out that calling Fl_Sys_Menu_Bar::replace(); will cause OSX to tear down
and rebuild the menu structure, and thus make it reflect the current state of
the check marks and so forth.
So, just pick a menu entry, then rename it to itself, and...
Something like this:
// Apple / OSX specific hack to force the menu to be rebuilt
// NOT needed on win32/linux...
int idx = mb1->find_index("File/item 1");
mb1->replace(idx, "item 1");
// end of menu rebuild hack...
Seems to work just fine. As a workaround.
A proper fix would be nice though!
Cheers,
