You are working too hard. Just add the virtual event to the widget
class and it will automatically be called for each menu widget:

bind Menu <<ThemeChanged>> {ChangeMenuColors %W}

Yes, there is plenty of introspection. For example, [. cget -menu]
will give you the menu associated with the main window. Given a menu
you can use the index command like [$menu index end] to get the index
of the last item. You can then loop from zero to that number, and use
entrycget to get the value for each item. And so on.

If you need to know what popup menus exist (ie: those not tied to a
toplevel with the -menu option) you can get a list of all widgets (I'm
usually lazy and do [info commands .*]) and pick out the ones you want
by looking at the widget class. In the case of menus you need to
exclude clones.

Have you looked at

set nEntries [$menu index end]
for {set i 1} {$i <= $nEntries} {incr i} {
puts stdout [join [$menu entryconfigure $i] \n]
}

For a cascade, there will be another menu widget entryconfigured as
-menu and you can do the same thing to that menu.

I seem to recall being confused by some of the things I found when I
first did this kind of thing but a quick test just now held no surprises.

Hope this helps!

Thanks for all your replies, especially Schelte who shows the KISS
rule of TCL.

Everything is now working correctly.
