[NativeMenu] handles low-level access to the OS native global menu bar and popup menus.
[b]Note:[/b] This is low-level API, consider using [MenuBar] with [member MenuBar.prefer_global_menu] set to [code]true[/code], and [PopupMenu] with [member PopupMenu.prefer_native_menu] set to [code]true[/code].
To create a menu, use [method create_menu], add menu items using [code]add_*_item[/code] methods. To remove a menu, use [method free_menu].
[codeblock]
var menu
func _menu_callback(item_id):
if item_id == "ITEM_CUT":
cut()
elif item_id == "ITEM_COPY":
copy()
elif item_id == "ITEM_PASTE":
paste()
func _enter_tree():
# Create new menu and add items:
menu = NativeMenu.create_menu()
NativeMenu.add_item(menu, "Cut", _menu_callback, Callable(), "ITEM_CUT")
NativeMenu.add_item(menu, "Copy", _menu_callback, Callable(), "ITEM_COPY")
NativeMenu.add_separator(menu)
NativeMenu.add_item(menu, "Paste", _menu_callback, Callable(), "ITEM_PASTE")
func _on_button_pressed():
# Show popup menu at mouse position:
NativeMenu.popup(menu, DisplayServer.mouse_get_position())
func _exit_tree():
# Remove menu when it's no longer needed:
NativeMenu.free_menu(menu)
