GUILayout not working for me C#

Question

Hello, I've coded the following OnGUI function. My Debug.Log methods are logging properly, showing that the code is getting reached. However, my GUI isn't showing up! Why is this?

 void OnGUI() {
     if (ShowRestartWindow) {
         #region Restart Window
 
         if (Event.current.type == EventType.Layout) {
             Debug.Log("layout");
             GUILayout.BeginArea(new Rect(10f, 10f, 100f, 100));
             {
                 Debug.Log("RestartWindow shown");
                 PlayerController pc = GetComponent<PlayerController>();
                 int playerScore = pc.playerDisplayedScore;
                 int highScore = pc.HighestPlayerScore;
 
                 GUILayout.Label("Your Score: " + playerScore.ToString());
                 GUILayout.Label("High Score: " + highScore.ToString());
 
                 if (GUILayout.Button("Play Again?")) {
                     //Time.timeScale = 1;
                     Application.LoadLevel("main");
                 }
 
             }
             GUILayout.EndArea();
         }
 
         #endregion
     }
 }

I think it would work without the guard on line 5.

This should be a comment, not an answer.

Also: It didn't work due to GUI Manipulation rules, that's why they're there in the first place.

@phxvyper: No, this should be an answer since it is correct. What "GUI Manipulation rules" are you talking about? OnGUI is called to process events. There are many different type of events. The layout event is only for gathering information about the controls you want to draw. The controls itself are drawn when the repaint event is issued. Input is processed when a mouse keyboard event is issued. Since you filter out all events but layout the whole system doesn't work.

@Bunny83 It isn't correct for my situation. I was manipulating a variable with affected the state of the GUI (somehow), and it caused an error to pop up. I googled the error and another person who had the issue posted it on unity answers. Someone replied with that if statement, the error is now gone because of it.

I used the repaint event in the if statement and it still showed the error.

Edit: I changed the GUI around a bit and removed that if statement. The changes i made didn't work until the if statement was removed. I'm unsure what exactly was creating that error. ~ so now it works
