public class CellRendererSpin : CellRendererText
CellRendererSpin renders text in a cell like CellRendererText from which it is derived.
The range of the spinbutton is taken from the adjustment property of the cell renderer, which can be set explicitly or mapped to a column in the tree model, like all properties of cell renders. CellRendererSpin also has properties for the climb_rate and the number of digits to display. Other SpinButton properties can be set in a handler for the editing_started signal.
The CellRendererSpin cell renderer was added in GTK+ 2.10.
