Previously I have posted an article on adding object specific context menu (that is, extending the context menu only when a particular entity type is selected.) Now, below code shows the procedure to extend the AutoCAD default context menu using API “AddDefaultContextMenuExtension”.
[CommandMethod("DefaultMenuTest")]static public void DefaultMenuTest()
{
ContextMenuExtension contectMenu =new ContextMenuExtension();contectMenu.Title = "Default Menu Test";MenuItem Item1 = new MenuItem("Test1");contectMenu.MenuItems.Add(Item1);MenuItem Item1a = new MenuItem("Sub Test1");Item1a.Click += new EventHandler(Item1a_Click);Item1.MenuItems.Add(Item1a);MenuItem Item2 = new MenuItem("Test2");Item2.Click += new EventHandler(Test2_Click);contectMenu.MenuItems.Add(Item2);//App Default menuApplication.AddDefaultContextMenuExtension(contectMenu);}
static void Item1a_Click(object sender, EventArgs e){
Application.ShowAlertDialog("Test1a clickedn");}
static void Test2_Click(object sender, EventArgs e){
Application.ShowAlertDialog("Test2 clickedn");}
