LVGL (Light and Versatile Graphics Library) is an open-source graphics library for embedded systems. It provides a range of graphical user interface (GUI) components, including message boxes.
A message box is a dialog box that displays a message to the user and requires the user to respond before continuing. In LVGL, you can create a message box using the lv_msgbox_create function.
Here's an example of how to create a message box in LVGL:
```
lv_obj_t * mbox = lv_msgbox_create(lv_scr_act(), NULL);
lv_msgbox_set_text(mbox, "Hello, world!");
lv_msgbox_start_auto_close(mbox, 2000);
```
In this example, we create a message box using the lv_msgbox_create function and set the text using the lv_msgbox_set_text function. We also use the lv_msgbox_start_auto_close function to automatically close the message box after 2 seconds.
You can customize the appearance of the message box using LVGL's style system. For example, you can set the background color, font, and button styles using the lv_style_t structure and the lv_obj_set_style function.
Overall, LVGL's message box component provides a simple and easy-to-use way to display messages to users in embedded systems.
