Add custom buttons to the Asset Management toolbar in the Graph window.
You can add custom buttons to the Asset Management toolbar by creating toolbar element classes and applying the 
[GraphToolbarElement]
attribute.

Prerequisites

You must have created and implemented a graph tool.

Create a toolbar element class

To create a toolbar element class, do the following:
  1. Create a class that inherits from any 
    VisualElement
    (
    EditorToolbarButton
    in the example below).
  2. Apply the 
    [GraphToolbarElement]
    attribute to bind it to your 
    Graph
    type.
  3. Implement 
    IAccessContainerWindow
    to get a reference to the editor window. This lets you access the current graph from within the button's click handler.
[GraphToolbarElement(id, typeof(MySimpleGraph), order: 200)]    class MyCustomToolbarAction : EditorToolbarButton, IAccessContainerWindow    {        public const string id = "MyGraphTool/CustomAction";        public EditorWindow containerWindow { get; set; }        public MyCustomToolbarAction()        {            text = "My Action";            tooltip = "Performs a custom action on the graph";            icon = EditorGUIUtility.IconContent("console.infoicon").image as Texture2D;            clicked += OnClick;        }        void OnClick()        {            if (containerWindow is IGraphWindow graphWindow)                UnityEngine.Debug.Log(graphWindow.Graph.Name);        }    }    #endregion CustomToolbarAction}
When you open your graph asset, your custom buttons appear in the Asset Management toolbar at the position determined by their 
order
value.
