自定义窗口中使用右键菜单：

// This example shows how to create a context menu inside a custom EditorWindow.class MyGenericMenu extends EditorWindow {        @MenuItem("Game/Open Window")    static function Init () { var window = GetWindow (MyGenericMenu); 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(); } } } }
