module Wx

  # A menu is a popup (or pull down) list of items, one of which may be selected before the menu goes away (clicking elsewhere dismisses the menu).
  # Menus may be used to construct either menu bars or popup menus.
  # A menu item has an integer ID associated with it which can be used to identify the selection, or to change the menu item in some way. A menu item with a special identifier {Wx::StandardID::ID_SEPARATOR} is a separator item and doesn't have an associated command but just makes a separator line appear in the menu.
  # Please note that {Wx::StandardID::ID_ABOUT} and {Wx::StandardID::ID_EXIT} are predefined by wxWidgets and have a special meaning since entries using these IDs will be taken out of the normal menus under macOS and will be inserted into the system menu (following the appropriate macOS interface guideline).
  # 
  # Menu items may be either normal items, check items or radio items. Normal items don't have any special properties while the check items have a boolean flag associated to them and they show a checkmark in the menu when the flag is set. wxWidgets automatically toggles the flag value when the item is clicked and its value may be retrieved using either {Wx::Menu#is_checked} method of {Wx::Menu} or {Wx::MenuBar} itself or by using {Wx::Event::IsChecked} when you get the menu notification for the item in question.
  # The radio items are similar to the check items except that all the other items in the same radio group are unchecked when a radio item is checked. The radio group is formed by a contiguous range of radio items, i.e. it starts at the first item of this kind and ends with the first item of a different kind (or the end of the menu). Notice that because the radio groups are defined in terms of the item positions inserting or removing the items in the menu containing the radio items risks to not work correctly.
  # 
  # == Allocation strategy
  # 
  # All menus must be created on the <b>heap</b> because all menus attached to a menubar or to another menu will be deleted by their parent when it is deleted. The only exception to this rule are the popup menus (i.e. menus used with {Wx::Window#popup_menu}) as wxWidgets does not destroy them to allow reusing the same menu more than once. But the exception applies only to the menus themselves and not to any submenus of popup menus which are still destroyed by wxWidgets as usual and so must be heap-allocated.
  # As the frame menubar is deleted by the frame itself, it means that normally all menus used are deleted automatically.
  # 
  # == Event handling
  # 
  # Event handlers for the commands generated by the menu items can be connected directly to the menu object itself using {Wx::EvtHandler#bind}. If this menu is a submenu of another one, the events from its items can also be processed in the parent menu and so on, recursively.
  # If the menu is part of a menu bar, then events can also be handled in {Wx::MenuBar} object.
  # Finally, menu events can also be handled in the associated window, which is either the {Wx::Frame} associated with the menu bar this menu belongs to or the window for which {Wx::Window#popup_menu} was called for the popup menus.
  # See Dynamic Event Handling for how to bind event handlers to the various objects.
