CellRendererSpinnerProtocol
public protocol CellRendererSpinnerProtocol : CellRendererProtocol
GtkCellRendererSpinner renders a spinning animation in a cell, very
similar to GtkSpinner
. It can often be used as an alternative
to a GtkCellRendererProgress
for displaying indefinite activity,
instead of actual progress.
To start the animation in a cell, set the GtkCellRendererSpinner:active
property to true
and increment the GtkCellRendererSpinner:pulse
property
at regular intervals. The usual way to set the cell renderer properties
for each cell is to bind them to columns in your tree model using e.g.
gtk_tree_view_column_add_attribute()
.
The CellRendererSpinnerProtocol
protocol exposes the methods and properties of an underlying GtkCellRendererSpinner
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 CellRendererSpinner
.
Alternatively, use CellRendererSpinnerRef
as a lighweight, unowned
reference if you already have an instance you just want to use.
