Question ObjectField : Catch MouseDownEvent while disabled

Hi,

I am using the UIElements API and trying to display an ObjectField with the state Disabled.

Here is my code :

Code (CSharp):

1. var objectField = new ObjectField("ObjectField");
2. objectField.value = mySO;
3. objectField.SetEnabled(false);

The ObjectField is showing good, with the state Disabled, but like the SetEnabled method says : "A disabled VisualElement does not receive mosts events."

My needs :
I would like to have the same behaviour as the IMGUI doing : clicking on the disabled ObjectField will ping the object reference (using EditorGUIUtility.PingObject())

I have tried to register an event with the RegisterCallback method, but it don't seems to be called (like SetEnabled says). I have the feeling that the element who catch the mouse event is disabled too.

Anyone have a suggestion to handle this issue ?

Thanks in advance

 

Alright, thanks for the answer.

For now, i'll go with this workaround:

Making an empty VisualElement who will catch the MouseDownEvent and place it in front of the disabled ObjectField.

Code (CSharp):

1.  
2. var objectField = new ObjectField("Disabled Object Field");
3. objectField .value = myObject;
4. objectField .SetEnabled(false);
5.  
6. VisualElement clickCatcherContainer = new VisualElement();
7. clickCatcherContainer .RegisterCallback<MouseDownEvent>((evt) => { EditorGUIUtility.PingObject(myObject); });
8. clickCatcherContainer.AddToClassList("clickcatcher-container");
9.  

I don't know if I can set the "top" parameter through c#, so I'm using a .uss file :

Code (csharp):

1.  
2. .clickcatcher-container
3. {
4.     top: -20px;
5.     height: 19px;
6. }
7.  

Hope this helps someone!

 

Here's the hack I am using to make the object field clickable while disabled in hierarchy

Code (CSharp):

1.  
2.         public static void ForceEnableClickable(this ObjectField objectField)
3.         {
4.             var obj = objectField.Q(className: ObjectField.objectUssClassName);
5.             var pseudoStatesProperty = typeof(VisualElement).GetProperty("pseudoStates", BindingFlags.Instance | BindingFlags.NonPublic);
6.             var states = (int)pseudoStatesProperty.GetValue(obj);
7.             pseudoStatesProperty.SetValue(obj, states & ~32/* PseudoStates.Disabled */);
8.         }
9.
