setIcon

Sets (or unsets) the icon on @menu_item.

This call is the same as calling g_icon_serialize() and using the result as the value to g_menu_item_set_attribute_value() for %G_MENU_ATTRIBUTE_ICON.

This API is only intended for use with "noun" menu items; things like bookmarks or applications in an "Open With" menu. Don't use it on menu items corresponding to verbs (eg: stock icons for 'Save' or 'Quit').

If @icon is null then the icon is unset.
