Description

The GenericMenu lets you create a custom context and dropdown menus.

The example below opens an Editor window with a green area. Context-clicking the green area shows a context menu, which triggers a callback to the script when an item is selected.

.

#pragma strict
// This example shows how to create a context menu inside a custom EditorWindow.
// context-click the green area to show the menu
public class GenericMenuExample extends EditorWindow {
	@MenuItem("Example/Open Window")
	static function Init() {
		var window: EditorWindow = GetWindow.<GenericMenuExample>();
		window.position = new Rect(50, 50, 250, 60);
		window.Show();
	}
	function Callback(obj: Object) {
		Debug.Log("Selected: " + obj);
	}
	function OnGUI() {
		var currentEvent: Event = Event.current;
		var contextRect: Rect = new Rect(10, 10, 100, 100);
		EditorGUI.DrawRect(contextRect, Color.green);
		if (currentEvent.type == EventType.ContextClick) {
			var mousePos: Vector2 = currentEvent.mousePosition;
			if (contextRect.Contains(mousePos)) {
				// Now create the menu, add items and show it
				var menu: GenericMenu = new GenericMenu();
				menu.AddItem(new GUIContent("MenuItem1"), false, Callback, "item 1");
				menu.AddItem(new GUIContent("MenuItem2"), false, Callback, "item 2");
				menu.AddSeparator("");
				menu.AddItem(new GUIContent("SubMenu/MenuItem3"), false, Callback, "item 3");
				menu.ShowAsContext();
				currentEvent.Use();
			}
		}
	}
