5.1	118	== 2.2 Install Software Running Environment ==
2.1	119
115.1	120
120.1	121	The ESP MCU supports development with ESP-IDF, Arduino, or MicroPython. We use ESP-IDF for compilation and Visual Studio Code (VS Code) as the development environment for this project.
2.1	122
115.1	123
120.1	124	=== 2.2.1 Install VS Code and ESP-IDF extension ===

121.1	162
133.2	163	[[image:squareline-studio-launcher-screen.png\|\|height="752" width="1415"]]
26.2	164
	165
131.1	166	Next, you need to configure some additional settings for this project. To do so, select File -> Project Settings as shown in the image below.
	167
26.2	168	[[image:1727229582471-566.png]]
	169
	170
131.1	171	In the PROJECT SETTINGS dialog box, configure/modify the project settings as shown in the image below.
121.1	172
	173	* UI Files Export Root: Select a folder on your computer to store the UI files.
	174	* LVGL Include Path: Set this to lvgl.h
131.1	175	* Click on the APPLY CHANGES button.
121.1	176
51.2	177	[[image:image-20240928105309-4.png\|\|height="526" width="556"]]
	178
26.2	179
131.1	180	Now you can start building the user interface. Follow the steps below:
26.2	181
121.1	182
123.2	183	=== Add widgets ===
26.2	184
123.2	185
131.1	186	To add a widget, navigate to the Widgets panel, and then click on the widget you want to add to the screen. You can reposition the widgets in the screen area by clicking and dragging them. Now add a Label, Button, and Image as shown in the image below. The added widgets are also displayed in the Hierarchy panel.
26.2	187
51.2	188	[[image:image-20240928111412-6.png\|\|height="526" width="864"]]
26.2	189
	190
131.1	191	Then click the Screen widget to add the second screen. After adding the second screen, it will appear in the Screens panel as Screen2.
26.2	192
131.1	193	[[image:Screenshot 2024-12-24 140459.png\|\|height="278" width="290"]]
	194
123.2	195	=== Modify widget properties ===
	196
	197
131.1	198	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.

26.2	201
	202
123.2	203	==== Changing the Button properties ====
122.1	204
123.2	205
131.1	206	Click the Button you have added to the screen. Under the Layout you can change the button's position and size. Use the following settings:
122.1	207
131.1	208	* Flex Flow: No Layout
	209	* Transform:
	210	X**: 331 px
	211	Y**: 203 px
	212	Width**: 100 px
	213	Height**: 50 px
	214	Align**: CENTER
122.1	215
51.2	216	[[image:1727485251053-655.png]]
26.2	217
	218
123.1	219	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	220
131.1	221	* Click ADD EVENT button. A new section will appear to configure this event.
26.2	222
131.1	223	[[image:Screenshot 2024-12-24 134937.png\|\|height="80" width="290"]]
	224
	225	* Select CLICKED from the dropdown under Trigger. Choose CHANGE SCREEN under Action, then click the ADD button. A new section will appear to configure the action.
	226
	227	[[image:Screenshot 2024-12-24 134818.png\|\|height="222" width="290"]]
	228
	229	* Select Screen2 under Screen to. Select FADE ON from Fade mode. The default value 500 means the transition takes 500 milliseconds to appear the Screen2.
	230	* Finally, click the ADD button.

51.2	235
	236
123.2	237	==== Changing the label properties ====
51.2	238
123.2	239
131.1	240	Click the Label you have added to the screen. Under the Label section, type "Click for Detail" in the Text textbox.
122.1	241
51.2	242	[[image:image-20240928090825-1.png\|\|height="327" width="391"]]
	243
	244
131.1	245	Once you enter the text, it will immediately appear on the label.
51.2	246
131.1	247
123.2	248	==== Changing image properties ====
122.1	249
123.2	250
131.1	251	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.
51.2	252
131.1	253	One way is to move your image into the folder "…/squareline project/assets/", as shown in the image below.
	254
51.2	255	[[image:image-20240928113424-9.png\|\|height="355" width="505"]]
	256
	257
131.1	258	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" panel in SquareLine Studio, as shown in the image below.
	259
51.2	260	[[image:image-20240928114139-10.png\|\|height="559" width="810"]]
	261
	262
123.2	263	==== The relationship between widgets ====
51.2	264
123.2	265
123.1	266	Widgets commonly have two types of relationships: parallel and parent-child.
	267
	268	* In a parallel relationship, widgets' positions are determined relative to a shared reference object.
132.1	269	* 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.
123.1	270
51.2	271	[[image:1727486567182-334.png\|\|height="318" width="278"]]
	272
	273
131.1	274	Move the label, Label1 to make it a child of Button1 as shown in the image below.
123.1	275
51.2	276	[[image:image-20240928112001-8.png\|\|height="431" width="796"]]
	277
	278
131.1	279	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.
51.2	280
131.1	281	[[image:Screenshot 2024-12-24 144005.png\|\|height="360" width="290"]]

	283
123.2	284	==== Preview the screen ====
51.2	285
123.2	286
132.1	287	You can test the result by clicking on the PLAY button as shown in the image below. The screen will change into play mode.
