    Accessibility is the accessibility of the application to users with disabilities (poor vision, hearing, etc.). They use special applications, screen readers, which read the text from the screen aloud or provide information from the screen in other ways (Braille code, for example).

    For screen readers to work, it is necessary that the applications provide information about what is displayed on the screen. Therefore, it is not enough just to draw pixels with letters on the screen, you need to report that you have drawn, for example, a button with some text.

    In the example above, the control reports that the label has changed. A screen reader can catch this event and, for example, read the updated text.
