Accessibility in mobile applications
On smartphones and tablets, there is an operating mode designed for visually impaired and blind users. This mode is called TalkBack on Android and VoiceOver on iOS. In version 2024, WINDEV Mobile allows you utilize these modes. Each control contains a generic description by default, and can contain a custom description.
By default, the generic description is the caption or hint text of the control.
You can customize the description using one of the following methods: - via the control description window.
- programmatically, using various WLanguage properties.
