	163	+
	164	+Now we can start to use this software. Here are some usage information for this software.
	165	+
	166	+**~1. add widget**
	167	+
	168	+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:image-20240928111412-6.png||height="526" width="864"]]
	171	+
	172	+ image 5 add widgets
	173	+
	174	+**2. modify widget**
	175	+
	176	+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".

	179	+
	180	+ image 6 the button widget's "Inspector" tab
	181	+
	182	+Second part: "Layout" means a auto position-management for widgets contained in the parent widget. "Transform" includes size, position and align modification.

	187	+
	188	+Third part: It is an area of style setting.
	189	+
	190	+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.

	195	+
	196	+**3. change label widget content**
	197	+
	198	+Modify the content in text as shown in image 9, the text content of label widget will be changed accordingly.

	203	+
	204	+**4. Add image into project**
	205	+
	206	+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.

	215	+
	216	+**5. The relationship between widgets**
	217	+
	218	+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	+**6. Preview the final effect**
	229	+
	230	+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.

	239	+== 2.4 Integrate UI Code to ESP-IDF Project ==
	240	+
	241	+
	242	+To achieve the integrating, we first need to export the UI code, then make some modifications, and finally relocate the UI code to a specific position within the project.

	275	+
	276	+The project consists of two screens. The first screen displays the company's logo, the project name, and a button to navigate to the next screen. The second screen presents some information about this HMI screen product through an image and includes a button to return to the previous screen.
