Keyboard control. The keyboard control displays an on-screen keyboard, from which users can select characters/symbols for entry into an application. The control can display different keyboard configurations, known as keytops. Users can toggle between the keytops using the selection keys provided. Note that most applications do not need to use this class directly. Controls should normally implement InputCapabilities() to return their text input capabilities, then the system takes care of displaying the virtual keyboard.

Keyboard observer interface. Objects implementing this interface may be set as the keyboard control observer using CQikKeyboardControl::SetObserver() . The functions handle key events from the keyboard control and handles size changes when the active keytop is changed.
