Dynamic EditorGuiLayout.PopUp list

Questions & Answers
1

Hello.

I am trying to use EditorGuiLayout.PopUp, but the string array is in another component attached to the same object.

I am using a PropertyAttribute and a CustomPropertyDrawer. I have to access the monobehaviour inside the drawer.

public class ClassA : MonoBehaviour 
{
  public List<Foo> foos = new List<Foo>();

  [Serializable]
  private class Foo 
  {
    [MyAttribute]
    public string field;
  {
   
  // custom property attribute
  public class MyAttribute : PropertyAttribute 
  {
  }
  
  [CustomPropertyDrawer(typeof(MyAttribute))]
  public class MyAttributeDrawer
  {
    public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
    {
      // how can I get the instance of classA ????
      ClassA a;
      
      // use getComponent
      string[] names = a.GetComponent<MyOtherComponent>().getNames();
      
      // draw
      Editor.PopUp( ... , names)
    }
  }
}

How can I access the instance of ClassA ?

Note: I have simplified the code to make it easier to read. Everything else works fine.

The answer was pretty simple.

 ClassA a = (ClassA) property.serializedObject.targetObject;
