Gtk.Cell_Renderer_Spinner

Description

Renders a spinning animation in a cell

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.
