26.2	205
	206
123.2	207	=== Modify widget properties ===
	208
	209
122.1	210	The area for modifying widgets is called the Inspector tab. The Inspector tab consists of four sections: COMPONENT, <WIDGET>, STYLE SETTINGS, and EVENTS, as shown in Image 6.
26.2	211
122.1	212	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.

123.1	228	Image 7: The button widget's "BUTTON" tab
26.2	229
122.1	230
123.1	231	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.
26.2	232
123.1	233	* Click ADD EVENT button.
	234	* Select CLICKED under the Trigger.
	235	* Select Screen2 from Screen to.
	236	* Select FADE ON from Fade mode.

123.2	255	==== Changing image properties ====
122.1	256
123.2	257
51.2	258	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.

	268
123.2	269	==== The relationship between widgets ====
51.2	270
123.2	271
123.1	272	Widgets commonly have two types of relationships: parallel and parent-child.
	273
	274	* In a parallel relationship, widgets' positions are determined relative to a shared reference object.
	275	* 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.
	276
51.2	277	[[image:1727486567182-334.png\|\|height="318" width="278"]]

26.2	300	== 2.4 Integrate UI Code to ESP-IDF Project ==
	301
56.1	302
26.2	303	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.

2.1	335
56.1	336
51.2	337	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.
	338
