*
* The spin box provides a control for entering an integer number. It
* consists of a line edit, and buttons which allow to increase or
* decrease the value. If you rather need input of a fractional
* number, use WDoubleSpinBox instead.
*
* %WSpinBox is an \link WWidget::setInline(bool) inline \endlink widget.
*
* \sa WDoubleSpinBox
*
* \note A spinbox configures a validator for validating the input. Therefore
* you cannot set a validator yourself.
