\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.
