CellRendererSpinProtocol
public protocol CellRendererSpinProtocol : CellRendererTextProtocol
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.
The GtkCellRendererSpin
cell renderer was added in GTK 2.10.
The CellRendererSpinProtocol
protocol exposes the methods and properties of an underlying GtkCellRendererSpin
instance.
The default implementation of these can be found in the protocol extension below.
For a concrete class that implements these methods and properties, see CellRendererSpin
.
Alternatively, use CellRendererSpinRef
as a lighweight, unowned
reference if you already have an instance you just want to use.
