How to run a method in Unity after rendering the GUI (void OnGUI () {})? in EditorWindow

Here I found the order of execution of the functions of events. But I still did not understand how to start the method, after the GUI rendering event (void OnGUI () {}).

Code (CSharp):

1. #if UNITY_EDITOR
2. public class Main : EditorWindow {
3.     [MenuItem ("Window/Panorama Terrain Tools")]
4.     public static void ShowWindow () {
5.         m_WindowMain = (Main) GetCustomWindow (true);
6.         // if(Main.m_WindowMain == null) { Main.m_WindowMain = (Main) Main.GetCustomWindow (true); }
7.         m_WindowMain.Show ();
8.     }
9.  
10.     public static Main GetCustomWindow (bool focus) {
11.         return GetWindow<Main> (" ", focus);
12.     }
13.  
14.  
15.     void OnEnable () {
16.  
17.     }
18.     void OnGUI () {
19.      ...
20.     }
21.  
22.     void SomeMethod(){
23.      Debug.Log("method to call after the method void OnGUI () {}");
24.     }
25. }
26. #endif

 

Since you are dealing with editor code, have you tried EditorApplication.delayCall or EditorApplication.update?

 

Besides the EditorApplication.delayCall that is called only once (but you can keep registering every time it is called), you can use this:

Code (CSharp):

1. void OnGUI()
2. {
3.     if (Event.current.type == EventType.Repaint)
4.     {
5.         // this will be processed after all others EventType
6.     }
7. }

 

can be described in more detail please EditorApplication.delayCall. There is no example in the documentation

 

I need to call the method once .... And not after each redraw

 

It's pretty simple, anytime you need a method to be called after all GUI calls you can just add that method to to the delegate, like so:

Code (CSharp):

1.  EditorApplication.delayCall += SomeMethod;
