public class VirtualKeyboard

extends TextField

Provides a graphical Vitural Keyboard interface text field control: <input type='text'>.

VirtualKeyboard enables text fields to be filled in using a mouse only. Password and textarea fields will be supported in later releases.

Virtual keyboard interfaces are generally used in websites where the highest level of security is a must like online banking applications. Virtual keyboards help to prevent any keylogging activies and/or provide users a special keyboard which they don�t already have (like a keyboard of another language).

Keyboard Layout Support

This controls comes with support for Arabic, Belgian, Dutch, Dvorak, French, German, Greek, Hebrew, Hungarian, Italian, Lithuanian, Norwegian, Number Pad, Polish Programmers, Portuguese, Russian, Slovenian, Spanish (Spain), Turkish-F, Turkish-QWERTY, UK, US Standard and US International keyboard layouts, dynamically selectable.

Credits

This control based on the Greywyvern JavaScript library. TODO: add support for password fields and textareas too.
