EditorWindow Inherits from ScriptableObject

Derive from this class to create an editor window.

Note: This is an editor class. To use it you have to place your script in Assets/Editor inside your project folder. Editor classes are in the UnityEditor namespace so for C# scripts you need to add "using UnityEditor;" at the beginning of the script.

Create your own custom editor window that can float free or be docked as a tab, just like the native windows in the Unity interface.

Editor windows are typically opened using a menu item.

// JavaScript example:
class MyWindow extends EditorWindow {
    var myString = "Hello World";
    var groupEnabled = false;
    var myBool = true;
    var myFloat = 1.23;
    
    // Add menu named "My Window" to the Window menu
    @MenuItem ("Window/My Window")
    static function Init () {
        // Get existing open window or if none, make a new one:        
        var window = ScriptableObject.CreateInstance.<MyWindow>();
    }
    
    function OnGUI () {
        GUILayout.Label ("Base Settings", EditorStyles.boldLabel);
            myString = EditorGUILayout.TextField ("Text Field", myString);
        
        groupEnabled = EditorGUILayout.BeginToggleGroup ("Optional Settings", groupEnabled);
            myBool = EditorGUILayout.Toggle ("Toggle", myBool);
            myFloat = EditorGUILayout.Slider ("Slider", myFloat, -3, 3);
        EditorGUILayout.EndToggleGroup ();
    }
}
// C# example:
using UnityEngine;
using UnityEditor;
public class MyWindow : EditorWindow {
    string myString = "Hello World";
    bool groupEnabled;
    bool myBool = true;
    float myFloat = 1.23f;
    
    // Add menu named "My Window" to the Window menu
    [MenuItem ("Window/My Window")]
    static void Init () {
        // Get existing open window or if none, make a new one:
        MyWindow window = (MyWindow)EditorWindow.GetWindow (typeof (MyWindow));
    }
    
    void OnGUI () {
        GUILayout.Label ("Base Settings", EditorStyles.boldLabel);
            myString = EditorGUILayout.TextField ("Text Field", myString);
        
        groupEnabled = EditorGUILayout.BeginToggleGroup ("Optional Settings", groupEnabled);
            myBool = EditorGUILayout.Toggle ("Toggle", myBool);
            myFloat = EditorGUILayout.Slider ("Slider", myFloat, -3, 3);
        EditorGUILayout.EndToggleGroup ();
    }
