+/**
+ * @short Spin box with a pair of spin buttons on either side.
+ *
+ * The SpinBox2 class provides a spin box with two pairs of spin buttons, one on either side.
+ *
+ * It is designed as a base class for implementing such facilities as time spin boxes, where
+ * the hours and minutes values are separately displayed in the edit field. When the
+ * appropriate step increments are configured, the left spin arrows can then be used to
+ * change the hours value, while the right spin arrows can be used to change the minutes
+ * value.
+ *
+ * Rather than using SpinBox2 directly for time entry, use in preference TimeSpinBox or
+ * TimeEdit classes which are tailored from SpinBox2 for this purpose.
+ *
+ * Separate step increments may optionally be specified for use when the shift key is
+ * held down. Typically these would be larger than the normal steps. Then, when the user
+ * clicks the spin buttons, he/she can increment or decrement the value faster by holding
+ * the shift key down.
+ *
+ * The widget may be set as read-only. This has the same effect as disabling it, except
+ * that its appearance is unchanged.
