\class XQVibra
\brief The XQVibra class is used to control the device's vibra. The XQVibra
class provides also information of vibration setting in the user profile.
Example:
\code
XQVibra *vibra = new XQVibra(this);
QPushButton *startButton = new QPushButton(this);
QPushButton *stopButton = new QPushButton(this);
connect(startButton, SIGNAL(clicked()), vibra, SLOT(start()));
connect(stopButton, SIGNAL(clicked()), vibra, SLOT(stop()));
\endcode
