I experience the same problem under NT 3.51 - I can't change the font of
widgets in a menubar. I suspect that it is due to a style restriction in
the Windows API (not IDL) - i.e., that Windows doesn't let you pick a
font for a menu "widget".
One can change menubar fonts freely under Unix.
By the way, I think that WIDGET_CONTROL,DEFAULT_FONT=... is one of those
"global" WIDGET CONTROL calls, even though the docs don't point this
out. (In fact the docs are misleading in that they state that
WIDGET_CONTROL requires a widget_id argument for all calls except /RESET.)
It ignores any widget-id argument you pass, and sets the font for all
widgets created subsequently. (If you explicitly specify a widget's
font via the /FONT keyword then this default is overridden, of course.)
It still would have worked in your case - that is, if Windows allowed it :)
