How can I add word wrap to EditorGUILayout.TextArea?

Question

How can I add word wrap to the editor textarea? I'm trying to mimic the [TextArea] attribute (word wrap, automatically increase height when needed)

For some reason GUILayout.TextArea() works fine, but EditorGUILayout.TextArea() doesn't have any word wrap. Here's my code:

obj.edibleFlavorText = EditorGUILayout.TextArea(obj.edibleFlavorText, GUILayout.MinHeight(textAreaHeight));

I've tried:

• Adding GUILayout.ExpandHeight(true) to its options

• Adding GUI.skin.textArea.wordWrap = true to the start of my editor script

In essence, You need to make sure that the style that is used has wordwrap set to true.

The problem with what you tried is that the style you edited isn't used by the TextArea.

Which style is used is actually a weird one, as I expected EditorStyles.textArea but for some reason, unity uses EditorStyles.textField as the default style instead...(which has wordwrap set to false).

So to fix it, just force it to use the correct style :p

EditorGUILayout.TextArea(obj.edibleFlavorText, EditorStyles.textArea);

On a side note, If you need to alter a style for one field, I wouldn't advise to change the built in GUI styles as doing that will change the style for ALL components that use that style (unless that is what you're after).

Instead, I would advise to create a copy of an existing style, modify it and use it for the component you want to edit.

So for example

        GUIStyle myStyle = new GUIStyle(EditorStyles.textField);
        myStyle.wordWrap = true;
        value = EditorGUILayout.TextArea(value, myStyle);
