Setting check menu item state without triggering

["Neil Hodgson" <neilh hare net au>]

    Hi,

    I have several check menu items in a menu and want to set their state
without triggering the menu item's signal function. Normally, the state is
changed when the user selects the item which all works well. Sometimes, such
as when loading preferences, I want to check and uncheck these items to
match the preferences. I tried the code in Developing Linux Applications
(Synchronizing Toolbar and Menu Items, starting page 96) but this results in
signals being sent.
