[SOLVED] Replicating GUILayout.TextArea

As an exercise I tried converting one of my custom inspectors to use UIElements.

In my original code I have a TextArea that uses a string field local to the inspector class.

Code (CSharp):

1. string json;
2.  
3. public override void OnInspectorGUI()
4. {
5.     json = GUILayout.TextArea(json);
6.  
7.     if (GUILayout.Button("Do something"))
8.     {
9.         // do something with json string
10.     }
11. }

I had to use IMGUIContainer for this bit as I just don't know how to get the TextArea working with UIElements. I tried using a TextField but when I click in it it just goes blank. Do I need to somehow bind it to the string field?

 

Ok, solved it.

I simply needed to register a callback for value changed.

Code (CSharp):

1.            
2.             var textField = new TextField();
3.             textField.RegisterValueChangedCallback((e) => {
4.                 json = textField.value = e.newValue;
5.             });
