221 -Next, add a click event to the button. When the button is clicked, an event should trigger to change the current screen (Screen1) to a new screen (Screen2) with a fade effect and the transition from Screen1 to Screen2 should take 500ms.

264 -
265 -==== **The relationship between widgets** ====
266 -
267 -
268 -Widgets commonly have two types of relationships: **parallel** and **parent-child**.
269 -
270 -* In a **parallel relationship**, widgets' positions are determined relative to a shared reference object.
271 -* In a **parent-child relationship**, any part of the child object outside the parent's boundaries is hidden by default. To make the child object fully visible, you must adjust its position to fit within the parent's range.
