EditorWindow

Learn to create a custom window with EditorWindow.

Independent Windows with EditorWindow

To create standalone, dockable windows like the Inspector or Hierarchy within the Unity interface, inherit from the EditorWindow class. The window is opened and brought to focus using the EditorWindow.GetWindow() method.

public class MapTool : EditorWindow
{
    // The window is opened using GetWindow
}

Rendering Window UI with OnGUI

The contents of an EditorWindow are rendered every frame inside its OnGUI() method. Layout utility classes such as GUILayout or EditorGUILayout are used to create buttons, sliders, and input fields.

void OnGUI()
{
    GUILayout.Label("Map Settings");
}

Exercise Show Editor Window

Open the window on screen by calling the win.Show(); method.

Show example solution

using System;

public class EditorWindow
{
    public string title = "Harita";
    public void Show() => Console.WriteLine("Pencere: " + title);
}

public class Program
{
    public static void Main()
    {
        EditorWindow win = new EditorWindow();
        win.Show();
    }
}
