append

Adds a new item or sub-menu to the menu.

• (send a-wx:menu append id name help-string checkable) -> void
      id : small integer
      name : string
      help-string = null : string
      checkable = #f : boolean

  Adds a new selectable item to the menu if id is a non-negative value. If help-string is not null, it may be used to display help information to the user. If checkable is not #f, then the menu item has a check-state that is changed with check. (When the user selects the item, the check state is automatically toggled.)

  The name string can contain special embedded codes to setup a keyboard binding for the menu item. Under MacOS, these key bindings are automatically performed; for other platforms, the binding is simply displayed in the menu item.

  Menu item key bindings are specified with a tab character. Under Windows and X Windows, the remainder of the string is displayed as the binding. Under MacOS, the remainder is ignored, unless it has of the form ``Cmd+X''; in this case, the menu item is bound to Cmd-X.

  Under Windows, the Alt key automatically switches to menu-selection mode. Include an ampersand (``&'') in the item name to set navigation keys for this mode. Under X Windows anfd MacOS, an ampersand in a menu item name is removed and ignored.

  Adds a new sub-menu to the menu if id is a non-negative value.
