221 -
222 -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.

253 -
254 -To use the **Image **widget, you should first add an image to your project. The image format must be PNG, and its resolution should not exceed 800x480 pixels. There are two ways to add an image file.
255 -
256 -One way is to move your image into the folder "…/squareline project/assets/", as shown in the image below.

265 -
266 -==== **The relationship between widgets** ====
267 -
268 -
269 -Widgets commonly have two types of relationships: **parallel** and **parent-child**.
270 -
271 -* In a **parallel relationship**, widgets' positions are determined relative to a shared reference object.
272 -* 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, as shown in Image 13.
273 -
274 -[[image:1727486567182-334.png||height="318" width="278"]]

280 -
281 -
282 -Then set the **X** and **Y** position of the label to **0** as shown in the image below. The label will appear on the button. If you move the button on the screen, the label will move along with it as part of the button.
