Overview

Renders a spin button in a cell

GtkCellRendererSpin renders text in a cell like GtkCellRendererText from which it is derived. But while GtkCellRendererText offers a simple entry to edit the text, GtkCellRendererSpin offers a GtkSpinButton 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. GtkCellRendererSpin also has properties for the GtkCellRendererSpin:climb-rate and the number of GtkCellRendererSpin:digits to display. Other GtkSpinButton properties can be set in a handler for the GtkCellRenderer::editing-started signal.
