Getting control ID to match with GUIUtility.hotControl

Unity Engine
1

How do I determine the ID of the last drawn GUI control? I’d like to be able to do something along these lines:

myObject.expanded = EditorGUILayout.Foldout(myObject.expanded, myObject.label);
int id = ???get control ID???;

if (GUI.hotControl == id) {
  // do something 
}

For example, I might want to render the foldout’s ‘child’ elements differently if the foldout is ‘hot’.

Is there such a function? Or, perhaps, a way to specify the ID for the next control, as GUI.SetNextControlName() does for the string identifier?

Ugly and nasty use of side effects but its the only soln I’ve found that works.
