How to get EditorWindow client rect?

Question

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?

Answer 1

Well, don't overwrite the width with your own value... :p

In my example I Use EditorGUILayout instead of GUILayout, but in this case that won't make a difference. The below code makes the scrollrect fill the entire window.

scrollPosition = EditorGUILayout.BeginScrollView(scrollPosition);

for (int i = 0; i < 100; i++)
{
    GUILayout.Label("Some long long long long text");
}

EditorGUILayout.EndScrollView();

In case you want to get the actual width of the window, see EditorGUIUtility.currentViewWidth

Turns out I used GUI.EndScrollView(), not GUILayout.EndScrollView().
