<description>
Returns the [PopupMenu] of this [RichTextLabel]. By default, this menu is displayed when right-clicking on the [RichTextLabel].
You can add custom menu items or remove standard ones. Make sure your IDs don't conflict with the standard ones (see [enum MenuItems]). For example:
[codeblocks]
[gdscript]
func _ready():
var menu = get_menu()
# Remove "Select All" item.
menu.remove_item(MENU_SELECT_ALL)
# Add custom items.
menu.add_separator()
menu.add_item("Duplicate Text", MENU_MAX + 1)
# Connect callback.
menu.id_pressed.connect(_on_item_pressed)
func _on_item_pressed(id):
if id == MENU_MAX + 1:
add_text("\n" + get_parsed_text())
[/gdscript]
[csharp]
public override void _Ready()
{
var menu = GetMenu();
// Remove "Select All" item.
menu.RemoveItem(RichTextLabel.MenuItems.SelectAll);
// Add custom items.
menu.AddSeparator();
menu.AddItem("Duplicate Text", RichTextLabel.MenuItems.Max + 1);
// Add event handler.
menu.IdPressed += OnItemPressed;
}
public void OnItemPressed(int id)
{
if (id == TextEdit.MenuItems.Max + 1)
{
AddText("\n" + GetParsedText());
}
}
