### Detailed Description

`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 climb rate and the number of digits to display. Other `GtkSpinButton` properties can be set in a handler for the start-editing signal.

The `GtkCellRendererSpin` cell renderer was added in GTK+ 2.10.

### Convenient Construction

### Properties

`adjustment` [`GtkAdjustment` : * : Read / Write]

  The acceleration rate when you hold down a button. Allowed values: >= 0 Default value: 0 Since 2.10

`digits` [numeric : Read / Write]
