EditorWindow Class, 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 : MyWindow = EditorWindow.GetWindow (MyWindow);
window.Show ();
}

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));
window.Show ();
}

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 ();
}
}
