\class HbInputVkbWidget
\brief A base class for touch keypads.

This class implements default mechanisms for opening and closing touch keypads.
It know how to operate in landscape and in portait modes and it know how
implement split view -mechasnism for S60 QT UI's Hb library. It also implements
closing mechansim, where used is able to close the touch keypad by sliding it downwards
with a finger. This class also implements background drawing for touch keypads.
