Resolved How to add a custom button to the top right corner of a editor window?

Hello guys, is there any way to add a custom button to the right of editor window's toolbar?
(just like help url )

 

[Solved] There is a Unity message "ShowButton(Rect position)" that can be used to draw UI on EditorWindow's toolbar. This message was not mentioned in Unity document page.

Code (CSharp):

1. public class MyWindow : EditorWindow
2. {
3.     private GUIStyle _toolbarButtonStyle;
4.  
5.     [MenuItem("Test/My Window")]
6.     public static void Open()
7.     {
8.         EditorWindow.GetWindow<MyWindow>();
9.     }
10.  
11.     /// <summary>
12.     /// Draw buttons on toolbar.
13.     /// Automatically called by unity.
14.     /// </summary>
15.     /// <param name="position"></param>
16.     private void ShowButton(Rect position)
17.     {
18.         // button style
19.         if (_toolbarButtonStyle == null)
20.         {
21.             _toolbarButtonStyle = new GUIStyle(GUI.skin.button)
22.             {
23.                 padding = new RectOffset()
24.             };
25.         }
26.  
27.         // draw button
28.         if (GUI.Button(position, EditorGUIUtility.IconContent("_Help"), _toolbarButtonStyle))
29.         {
30.             Application.OpenURL("https://docs.unity3d.com/Manual/index.html");
31.         }
32.     }
33. }

 

Thanks! Very useful

 

Hello there ! Does anyone know if an equivalent exists for component header toolbar ?

 

According to these codes, there are well done, although I used GuiLayout.Buttont(); but the style code and iconContent code are very helpful

 

Simplified code and corrected button style (removing the gray background of the button):

Code (CSharp):

1. private void ShowButton(Rect position)
2. {
3.     // draw button
4.     if (GUI.Button(position, EditorGUIUtility.IconContent("_Help"), GUI.skin.FindStyle("IconButton")))
5.     {
6.         Application.OpenURL("https://docs.unity3d.com/Manual/index.html");
7.     }
8. }
