How to get EditorWindow client rect?

Questions & Answers

I want to create a simple console-like custom EditorWindow in Unity. There is a bunch of lables (console lines).

I’m using GUILayout.Begi/EndScrollView to position all the labels in one column. The problem is that it places all the content inside the rectangle that matches label bounds, not EditowWindow bounds. As a result, I see weird placed scrollbars.

I would be happy to recalculate ScrollView bounds, but can’t find any clue in documentation how to make so. Here is my code:

using UnityEditor;
using UnityEngine;
using System;
 
public class MyEditorWindow : EditorWindow
{
   Vector2 scrollPosition = Vector2.zero;
 
   [MenuItem("Window/MyEditorWindow")]
   public static void ShowExample()
   {
       var wnd = GetWindow<MyEditorWindow>();
       wnd.titleContent = new GUIContent("MyEditorWindow");
   }
 
   private void OnGUI()
   {
       scrollPosition = GUILayout.BeginScrollView(scrollPosition, GUILayout.Width(position.width), GUILayout.Height(position.height));
 
       var elapsed = new TimeSpan();
       for (int i = 0; i < 100; i++)
       {
           elapsed = elapsed.Add(TimeSpan.FromSeconds(1));
       }
 
       for (int i = 0; i < 100; i++)
       {
           GUILayout.Label("Some long long long long text");
       }
 
       GUI.EndScrollView();
   }
}

What is the proper way of making scrolbars which bound to the edges of the EditorWindow?

Well, the layout system can only distribute the area that is available to the current layout group. For some reason the automatic top layout group has a fix width. Just wrap your code with a GUILayout area:

GUILayout.BeginArea(new Rect(0,0,position.width, position.height));
scrollPosition = GUILayout.BeginScrollView(scrollPosition);

// [ ... ]

GUI.EndScrollView();
GUILayout.EndArea();

edit
Ahh I just realised your mistake ^^. You used GUI.EndScrollView and not GUILayout.EndScrollView. That’s why the layouted rect is completely wrong. So just do

scrollPosition = GUILayout.BeginScrollView(scrollPosition);

// [ ... ]

GUILayout.EndScrollView();

And your scrollview should cover the whole window.
