# Event > A UnityGUI event. ## Definition * **Type:** Class * **Namespace:** [UnityEngine](/engine/6000.0/script-reference/unityengine.md) * **Assembly:** UnityEngine.IMGUIModule ```csharp public sealed class Event ``` ## Remarks Events correspond to user input (key presses, mouse actions), or are UnityGUI layout or rendering events. For each event [MonoBehaviour.OnGUI()](/engine/6000.0/script-reference/unityengine/monobehaviour/ongui.md) is called in the scripts; so OnGUI is potentially called multiple times per frame. [Event.current](/engine/6000.0/script-reference/unityengine/event/current.md) corresponds to "current" event inside OnGUI call.
