Help with scroll bars in an Editor Window

Unity Engine
1

Hi I’m trying to add scroll bars to my editor window so I can effectively look around a graph I’ll be making. Here I’ve made a comically large button to represent the graph. I am unable to use the scroll bars to scroll along the length of the button despite the fact that the Area Rect and button is too large to view, what am I doing wrong?

Thanks for any help.

public class DemoWindow: EditorWindow{

	Vector2 scrollPos = Vector2.zero;

        void OnGUI(){

		scrollPos = EditorGUILayout.BeginScrollView(scrollPos, true, true, GUILayout.Width(window.position.width), GUILayout.Height(window.position.height));

		GUILayout.BeginArea(new Rect(0, 0, 1500, 1500));
		GUILayout.Button("Test", GUILayout.Width(1500));
		GUILayout.EndArea();
		EditorGUILayout.EndScrollView();

    }
}

The problem seems to be with having a GUILayout Area with in the scroll view, without the GUI Area then the scroll bars will function correctly.

using UnityEngine;
using System.Collections;

public class TestScrollView : MonoBehaviour {
	
	Vector2 scrollPosition = Vector2.zero;
	
	void OnGUI(){
		scrollPosition = GUILayout.BeginScrollView(scrollPosition, true, true,  GUILayout.Width(100),  GUILayout.Height(100));	
		//GUILayout.BeginArea(new Rect(0, 0, 300, 300));	//Does not display correctly if this is not commented out!
		
		GUILayout.Button("I am a button", GUILayout.MinWidth(150), GUILayout.MinHeight(150));
		
		//GUILayout.EndArea();
		GUILayout.EndScrollView();
	}
}

If you want the scrollbar to set automatically according to items in your EditorWindow do this

Vector2 scrollPosition = Vector2.zero;
private void OnGUI()
{
scrollPosition = GUILayout.BeginScrollView(scrollPosition, false, true);

//Your Functions…

GUILayout.EndScrollView();
}
