Description
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 “active”
property to TRUE and increment the “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().
Functions
gtk_cell_renderer_spinner_new ()
GtkCellRenderer *
gtk_cell_renderer_spinner_new (void);
Returns a new cell renderer which will show a spinner to indicate activity.
Since 2.20
