Spin Box
This widget can be used as a spin box in the Frontend to adjust the value of a connected parameter. You can connect the widget to parameters with integer values. In contrast to the Slider widget, the spin box allows you to set the parameter values precisely to a specific value. This is helpful in case the parameter value shall be set to a precise value. If there are only very few values to choose from you can also use the Radio Button Group widget.
