Sending a "Rename" CommandEvent to the Hiearchy window, almost there...

Question

This is some what related to this question - but not about sending keys, but about the functionality I wanted from sending the keys.

I'm still looking for a way to engage in rename mode in the hierarchy via code - maybe get an access to the context menu that appears (which has Rename, Duplicate, Copy, Paste, etc)

So I got close this time, with the help of @Jamora, he told me about EditorGUIUtility.CommandEvent - All I needed to do now, is to find a way to give focus to the hierarchy window, I managed to do this via executing the menu item "Window/Hiearchy" - And indeed, I managed to access those options!

         var go = new GameObject("[Generated] Temp");
         Utils.SelectObject(go);
         EditorApplication.ExecuteMenuItem("Window/Hierarchy"); // focus on the hierarchy window
         EditorWindow.focusedWindow.SendEvent(EditorGUIUtility.CommandEvent("Duplicate")); // send an event, to the current focused window, which is the hierarchy at this point...

(All SelectObject does is Selection.objects = new Object[] { obj };)

Duplicate, Copy, Paste, etc all of these work, except for Rename! Give me a break!

For some reason it just won't work, nothing happens when I send a Rename, the hierarchy gets focus and,... nothing else.

I tried "Rename", "rename", "RENAME" no dice.

Any ideas why rename mode isn't engaging (while it should)?

Thanks!

EDIT:

Thanks to @ArkaneX - I was able to send a rename event, but for some reason sending the event immediately after I create a new GO, doesn't seem to do anything (doesn't engage rename mode):

     if (GUILayout.Button("Create")) {
         var go = new GameObject("[Generated] New GO");
         Utils.EngageRenameMode(go);
     }

Where:

 public static void EngageRenameMode(Object go)
 {
     SelectObject(go);
     GetFocusedWindow("Hierarchy").SendEvent(Events.Rename);
 }

 public static void SelectObject(Object obj)
 {
     Selection.objects = new Object[] { obj };
 }

 public static EditorWindow GetFocusedWindow(string window)
 {
     FocusOnWindow(window);
     return EditorWindow.focusedWindow;
 }

 public static void FocusOnWindow(string window)
 {
     EditorApplication.ExecuteMenuItem("Window/" + window);
 }

 public static class Events
 {
     public static Event Rename = new Event() { keyCode = KeyCode.F2, type = EventType.KeyDown };
 }

Again, this only doesn't seem to work when I'm creating a new GO and then renaming. Not sure why...

Hmmm. There's no Edit\\Rename command in my version of Unity. Are you sure you have this command?

But you can do this using F12. I answered your original question, but posting solution here as well:

 var e = new Event { keyCode = KeyCode.F2, type = EventType.keyDown }; // or Event.KeyboardEvent("f2");
 EditorWindow.focusedWindow.SendEvent(e);

EDIT: I think the problem might be related to the fact, that adding a game object (internally, by Unity Editor) is a complex process, which involves many steps and requires some time to fully finish. I was able to workaround this, but you have to either seek a way to determine when the object is fully created in editor or live with an arbitrary delay. I used a delay of 0.2s, but for example 0.1s was too low in my environment - you have to experiment.

 public class EventsTest : EditorWindow
 {
     private static GameObject go;
     private static double renameTime;
 
     [MenuItem("Test/Events")]
     private static void Test ()
     {
         go = new GameObject("[Generated] New GO");
         renameTime = EditorApplication.timeSinceStartup + 0.2d;
         EditorApplication.update += EngageRenameMode;
     }
 
     private static void EngageRenameMode()
     {
         if (EditorApplication.timeSinceStartup >= renameTime)
         {
             EditorApplication.update -= EngageRenameMode;
             Utils.EngageRenameMode(go);
         }
     }
 }

Brilliant! I didn't know you could create events like that

FYI, I don't have Rename in Edit menu, but I do have it when I right click an object in the hierarchy window.

I didn't know as well. But out of curiosity checked Event class returned by CommandEvent ;)

Right - there's one in context menu, but I think it is treated differently and is not considered a standard command.

Here's a solution via reflection. This is the same method that gets called when you F2 or Right Click | Rename.

 [MenuItem("Test/Rename")]
 public static void Rename()
 {
     var type = typeof(EditorWindow).Assembly.GetType("UnityEditor.SceneHierarchyWindow");
     var hierarchyWindow = EditorWindow.GetWindow(type);
     var rename = type.GetMethod("RenameGO", BindingFlags.Instance | BindingFlags.NonPublic);
     rename.Invoke(hierarchyWindow, null);
 }
