Detailed Description

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.
