184 184  
185 -The area for modifying widgets is called "Inspector". There are four parts in the "Inspector" tab. We use three of them more frequently, excluding "COMPONENT". The second part is aimed at adjusting the layout, size, position, alignment, flags, and states, etc. of widgets. The name of the second part indicates the type of widget it is representing, and in image 6, it is "BUTTON".

200 +The area for modifying widgets is called the **Inspector** panel. The Inspector panel consists of four sections: **COMPONENT**, **<WIDGET>**, **STYLE SETTINGS**, and **EVENTS**, as shown in the image below. The second section allows you to adjust a widget's layout, size, position, alignment, flags, states, and more. When you select a widget on the screen, the name of this section changes to match the name of the selected widget.

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.
198 198  
199 -Fourth part: It is an area for adding events. In image 8, it is adding a click event to a button. If the button is clicked after the click event is added as shown in image 8, the current screen will fade into another specified screen, and the switching process will last 500ms.
223 +* Click **ADD EVENT** button. A new section will appear to configure this event.

There are two ways to add an image file. One way is to move your image into the folder "…/squareline project/assets/", as shown in image 10. The other way is to click the "ADD FILE INTO ASSETS" button, then select an image from your computer to import. After adding, you can see the image in the "assets" area in SquareLine Studio, as demonstrated in image 11.

225 -**5. The relationship between widgets**
265 +==== **The relationship between widgets** ====
226 226  
227 -There are two common relationships between widgets: one is parallel, the other is parent-child. The parallel relationship means that widgets' relative position is based on a collective object of reference. In parent-child relationship, the parts of the child object that are outside the boundaries of the parent object are not visible by default. Therefore, we need to adjust the position of the child object so that it falls within the range of the parent object, allowing it to be seen as illustrated in image 13.
228 228  
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.

281 +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.
238 238  
239 -An advantage of this kind of software is that you can edit the UI with quick previews. In other words, it provides a way of combining graphical programming with simulation immediately.
