Arguments: menu
This menu property has an effect only on the GTK platform.
If nil
(the default), then keyboard shortcuts
for menu commands will be handled using GTK's own facility for
shortcuts. This allows the shortcut strings to be neatly right-aligned
on the menus. But it means that GTK will always handle a menu
command shortcut, and not allow Common Graphics to override that
behavior in certain cases. In particular, a shortcut will still invoke
a menu-item when a modal dialog is present, even if the menu-item's
allow-during-modality property
is nil
to prevent just that. Also, a
graphical keyboard shortcut that does not include either the Control
key or the Alt key would prevent the user from typing the shortcut
character into a text-editing widget. And the rather obscure
proxy-menu-bar-window feature
would not work. nil
is nevertheless the
default value, on the assumption that most applications will not use
these particular other Common Graphics features, and would prefer
normal-looking menus.
If true, then all Common Graphics menu functionality such as allow-during-modality will work as documented. But the shortcut strings will not be neatly right-aligned on the menus.
Mac OS X note: On the Mac, the default value of this property
is currently true, due to an unsolved problem with using native GTK
shortcuts. The value could still be set
to nil
for nicer looking menu strings, but if
a menu bar contains both a control-foo shortcut and a control-alt-foo
shortcut, then typing the control-alt-foo shortcut would actually
invoke the menu command for the control-foo shortcut.
