Description:
public class CellRendererSpin : CellRendererText
CellRendererSpin renders text in a cell like CellRendererText from which it is derived.
But while CellRendererText offers a simple entry to edit the text, CellRendererSpin offers a SpinButton widget. Of course, that means that the text has to be parseable as a floating point number.
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.
