/**
* Class TKeyboard.
*
* TKeyboard displays a virtual keyboard that users can click on to enter input in
* an associated text box. It helps to reduce the keyboard recording hacking.
*
* To use TKeyboard, write a template like following:
* <code>
* <com:TTextBox ID="PasswordInput" />
* <com:TKeyboard ForControl="PasswordInput" />
* </code>
*
* A TKeyboard control is associated with a {@link TTextBox} control by specifying {@link setForControl ForControl}
* to be the ID of that control. When the textbox is in focus, a virtual keyboard will pop up; and when
* the text box is losing focus, the keyboard will hide automatically. Set {@link setAutoHide AutoHide} to
* false to keep the keyboard showing all the time.
*
* The appearance of the keyboard can also be changed by specifying a customized CSS file via
* {@link setCssUrl CssUrl}. By default, the CSS class name for the keyboard is 'Keyboard'. This may
* also be changed by specifying {@link setKeyboardCssClass KeyboardCssClass}.
