[SOLVED] Custom Property Drawer without folding

Unity Engine
1

Hello,

I have a custom property drawer to print an integer vector as read-only value.

The code is like this:

[CustomPropertyDrawer(typeof(IntVector4))]
public class IntVector4Drawer : PropertyDrawer
  {
    public override void OnGUI(Rect Position, SerializedProperty Property, GUIContent Label)
    {
      IntVector4 Vector = new IntVector4(
        Property.FindPropertyRelative("mX").intValue,
        Property.FindPropertyRelative("mY").intValue,
        Property.FindPropertyRelative("mZ").intValue,
        Property.FindPropertyRelative("mW").intValue
        );
     
      EditorGUI.BeginProperty(Position, Label, Property);
      Position = EditorGUI.PrefixLabel(Position, Label);
      EditorGUI.PropertyField(Position, Property, new GUIContent(Vector.ToString()));
      EditorGUI.EndProperty();
    
    }
  }

Basically everything works: The values are visible in the inspector as read-only values. However the values have this little folding arrow at the side and I can fold and unfold them, even if there is no content to unfold. Is there any possibility to get rid of this folding symbol?

If you want it read only then ditch all the property stuff and instead use:

EditorGuiLayout.LabelField (or probably EditorGUI.LabelField in your case)

Thank you, it solves perfectly my issue here.

The final code is:

public override void OnGUI(Rect Position, SerializedProperty Property, GUIContent Label)
{
  IntVector4 Vector = new IntVector4(
    Property.FindPropertyRelative("mX").intValue,
    Property.FindPropertyRelative("mY").intValue,
    Property.FindPropertyRelative("mZ").intValue,
    Property.FindPropertyRelative("mW").intValue
    );
  
  Position = EditorGUI.PrefixLabel(Position, Label);
  EditorGUI.LabelField(Position, Vector.ToString());     
}

And this is how it looks now:
