# UI Toolkit Events

Learn about how the UI Toolkit Event System works in Unity 6 and how it differs from UGUI.

Watch this video to learn about how the UI Toolkit Event System works in Unity 6 and how it differs from UGUI. We’ll take a look at the Trickle-Down, Target, and Bubble-Up propagation phases. You’ll see how to handle clicks, drags, hovers, and focus using pointer and keyboard events, and how to code callbacks with RegisterCallback and UnregisterCallback for responsive logic.
