I went through this conundrum myself recently.
Here is my callback:
void cb_ShowPreview(Fl_Widget *w, void *)
{
const Fl_Menu_Item *mi = ((Fl_Menu_ *)w)->mvalue();
auto v = mi->checked();
togglePreview(v != 0);
}
As you can hopefully see, the widget passed to the callback is the MENU, not the MENU-ITEM.
I have a Fl_Menu_Button with some menu items inside it. The menu items look like this:{ {"label", 0, reinterpret_cast<Fl_Callback*>(callback), 0, FL_MENU_TOGGLE}, {nullptr}} ...
For whatever reason, it always returns FL_MENU_VALUE (4), regardless of whether I checked or unchecked the box. From the docs it says it should return 0 if the item is not checked. Where have I gone wrong?
