CellRendererSpinProtocol
public protocol CellRendererSpinProtocol : CellRendererTextProtocol
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.
