[Solved] Left Click with GenericMenu

Unity Engine
1

I’ve been looking for a way to left click with the Generic Menu. Ideally I’ll be doing this on a button element. I so far haven’t been able to find anything with left-clicks. If anyone has any tips or tricks on how to do this that would be great!

Thanks in advance!

Managed to find a solution after some more digging (still learning GUI via scripting). I ended up combining a few different event types with the GenericMenu to get what I needed. See a modified example from the GenericMenu page below. Hope this helps someone else!

using UnityEngine;
using UnityEditor;
using System.Collections;

// This example shows how to create a context menu inside a custom EditorWindow.
// left-click the green area to show the menu

public class GenericMenuExample : EditorWindow
{

    [MenuItem("Example/Open Window")]
    static void Init()
    {
        EditorWindow window = GetWindow<GenericMenuExample>();
        window.position = new Rect(50, 50, 250, 60);
        window.Show();
    }

    void Callback(object obj)
    {
        Debug.Log("Selected: " + obj);
    }

    void OnGUI()
    {
        Event currentEvent = Event.current;
        Rect contextRect = new Rect(10, 10, 100, 100);
        EditorGUI.DrawRect(contextRect, Color.green);

        if (currentEvent.button == 0 && currentEvent.isMouse)
        {
            Vector2 mousePos = currentEvent.mousePosition;
            if (contextRect.Contains(mousePos))
            {
                // Now create the menu, add items and show it
                GenericMenu menu = new GenericMenu();
                menu.AddItem(new GUIContent("MenuItem1"), false, Callback, "item 1");
                menu.AddItem(new GUIContent("MenuItem2"), false, Callback, "item 2");
                menu.AddSeparator("");
                menu.AddItem(new GUIContent("SubMenu/MenuItem3"), false, Callback, "item 3");
                menu.ShowAsContext();
                currentEvent.Use();
            }
        }
    }
}
