3.32  menu-item%

Implements: selectable-menu-item<%>

A menu-item% is a plain string-labelled menu item. Its parent must be a menu% or popup-menu%. When the user selects the menu item, its callback procedure is called.

• (new menu-item% (label _) (parent _) (callback _) [(shortcut _)] [(help-string _)] [(demand-callback _)]) -> menu-item% object
     label : string (up to 200 characters)
     parent : menu% or popup-menu% object
     callback : procedure of two arguments: a menu-item% object and a control-event% object
     shortcut = #f : character or #f
   help-string = #f : string (up to 200 characters) or #f
   demand-callback = void : procedure of one argument: a menu-item% object

  Creates a new menu item in parent. The item is initially shown, appended to the end of its parent. The callback procedure is called (with the event type 'menu) when the user selects the menu item (either via a menu bar, popup-menu in window<%>, or popup-menu in editor-admin%).

  See set-label for information about mnemonic ampersands (``&'') in label.

  If shortcut is not #f, the item has a shortcut. See get-shortcut for more information.

  If help-string is not #f, the item has a help string. See get-help-string for more information.

  The demand-callback procedure is called by the default on-demand method with the object itself.
