The gtk:cell-renderer-spin object renders text in a cell like the gtk:cell-renderer-text object from which it is derived. But while the gtk:cell-renderer-text object offers a simple entry to edit the text, the gtk:cell-renderer-spin object offers a gtk:spin-button widget. Of course, that means that the text has to be parseable as a floating point number.

The range of the spin button 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. The gtk:cell-renderer-spin object also has the climb-rate and digits properties to display. Other gtk:spin-button properties can be set in a handler for the "editing-started" signal.
