GenericMenu

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

Note: This is an editor class. To use it you have to place your script in Assets/Editor inside your project folder. Editor classes are in the UnityEditor namespace so for C# scripts you need to add "using UnityEditor;" at the beginning of the script.

// This example shows how to create a context menu inside a custom EditorWindow.

class MyWindow extends EditorWindow {
    
    @MenuItem("TestContextMenu/Open Window")
    static function Init () {
        var window = GetWindow (MyWindow);
        window.position = Rect (50, 50, 250, 60);
        window.Show ();
    }

    function Callback (obj:Object) {
        Debug.Log ("Selected: " + obj);
    }

    function OnGUI() {
        var evt : Event = Event.current;
        var contextRect : Rect = new Rect (10, 10, 100, 100);
        
        if (evt.type == EventType.ContextClick)
        {
            var mousePos : Vector2 = evt.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 ();

                evt.Use();
            }
        }
