Rect The last used rectangle.
Get the rectangle last used by GUILayout for a control.
Note that this only works during the Repaint event.
using UnityEngine;
public class ExampleScript : MonoBehaviour { void OnGUI() { GUILayout.Button("My button"); if (Event.current.type == EventType.Repaint && GUILayoutUtility.GetLastRect().Contains(Event.current.mousePosition)) { GUILayout.Label("Mouse over!"); } else { GUILayout.Label("Mouse somewhere else"); } } }
