How can I make a any UI Element open a ContextMenu when right clicked

Hello!

I've been trying to add a simple context menu when the user right-clicks on a certain element.

I have it set up like that:

Code (CSharp):

1. myUIElement.RegisterCallback((ContextualMenuPopulateEvent evt) =>
2. {
3.     evt.menu.AppendAction("ActionA", (x)=>{});  
4.     evt.menu.AppendAction("ActionB", (x)=>{});
5. });

The event never gets fired. It only works if I add a child UI element that already supports the right-click feature like a text field. Like so:

Code (CSharp):

1. myUIElement.RegisterCallback(...);
2. myUIElement.Add(new TextField());

What am I missing?

(For the sake of example, let's say the element I want to right click is a TextElement)

 

@uDamian It doesn't seem to work. I have this

Code (CSharp):

1. var element = root.Q<Toggle>(name: "online");
2. element.focusable = true;
3. element.pickingMode = PickingMode.Position;
4. element.RegisterCallback((ContextualMenuPopulateEvent evt) =>
5. {
6.     UnityEngine.Debug.Log("right click");
7. });
8.  

 

@uDamian That worked perfectly, thanks for the help!

 

Hello. I'm arriving late, but I think I can enjoy the subject.
I'm trying to add more menus to my graphview's context menu. I have no idea.
I was try the normal way, but dnt work:

 

@neoneper I am trying to do the same thing. Did you solve this?

Edit:

I was able to solve the question that @neoneper asked - which is to add an item to the GraphView context menu.

Here's how:

• On your class that inherits from GraphView, override the BuildContextualMenu method.
• You can add items to the menu by Appending / Inserting (see code below).
• Make sure that you check for the target to be GraphView or Node - otherwise you'll get a null reference.

Code (CSharp):

1.  
2. public class BehaviorTreeGraphView : GraphView
3. {      
4.     public override void BuildContextualMenu(ContextualMenuPopulateEvent evt)
5.     {
6.             base.BuildContextualMenu(evt);
7.  
8.             if (evt.target is GraphView || evt.target is Node)
9.             {
10.                 evt.menu.AppendAction("Testing", (e) => { Debug.Log("Test"); });
11.             }
12.      }
13. }
14.

@uDamian I am trying to do this in Treeview. The ContextMenu worked, but there is a problem:

• a new treeviewitem will not be selected when right clicked. And the last selected item is still be selected.

How can I do to right-click select which I want?
(ps. IMGUI treeview can work it.)

 

Necro!

Hello. I'm trying to create a TreeView and add a ContextMenu to the entire view, as well as expand it with an additional item when right-clicking on a specific element, but I'm having trouble. Can anyone help?
