GUI, Inspector has no control for Arrays?

Questions & Answers
1

Well, the default inspector I see has a control for Arrays, when I have "public int myInt;", the inspector knows it is an integer, and when drawing the object inspector, it displays an int-field control to handle that variable.. however, if I was to have an array like Object[] or List, the inspector can determine that it is an array, and draw the appropriate inspector, much like for integers, floats, and enumerators; However..

I cannot for the life of me figure out the control they used to ~inspect~ the arrays; D=

Any in-sight on this? I've actually made my own.. but it doesn't look the same as the built-in one, and I don't want people at all confused, so I am hoping someone has some info on how to use the array inspector that's built in.. thank you!

EditorGUILayout.Foldout is a special toggle control that is the little arrow used in the array (and other group) controls. e.g.

bool expanded = false;

void OnInspectorGUI()
{
  ...
  expanded = EditorGUILayout.Foldout( expanded, "My Array" );
  if( expanded )
  {
    // draw count and elements
  }
}

If you combine EditorGUILayout.BeginToggleGroup(...) (and, subsequently, EndToggleGroup(...)) and an array of EditorGUILayout.ObjectField(...)'s (or whatever the type of the Array is), you should get the effect you're looking for.
