The adjustment property of type gtk:adjustment (Read / Write)
The adjustment that holds the value of the spin button. This must be non-nil for the cell renderer to be editable.
climb-rate
The climb-rate property of type :double (Read / Write) The acceleration rate when you hold down a button. Allowed values: >= 0 Default value: 0
digits
The digits property of type :uint (Read / Write) The number of decimal places to display. Allowed values: <= 20 Default value: 0
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. Other gtk:spin-button properties can be set in a handler for the "editing-started" signal.
Warning
The gtk:cell-renderer-spin object is deprecated since 4.10. List
views use widgets to display their contents. You should use the gtk:spin-button widget instead.
