162 -Now we can start to use this software. Here are some usage information for this software.
163 -
164 -**~1. add widget**
165 -
166 -To add a widget, you should click a widget you want to add at the area entitled “Widgets”. In image , demonstrate a add process of label, button, and image 5.

169 -
170 - image 5 add widgets
171 -
172 -**2. modify widget**
173 -
174 -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".

177 -
178 - image 6 the button widget's "Inspector" tab
179 -
180 -Second part: "Layout" means a auto position-management for widgets contained in the parent widget. "Transform" includes size, position and align modification.

184 -image 7 the button widget's "BUTTON" tab
185 -
186 -Third part: It is an area of style setting.
187 -
188 -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.

200 - image 9 modify text content of label widget
201 -
202 -**4. Add image into project**
203 -
204 -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. 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.

212 - image 11 use image widget in SquareLine Studio
213 -
214 -**5. The relationship between widgets**
215 -
216 -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.

226 -**6. Preview the final effect**
227 -
228 -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.
