Use the toggled signal on the renderer like this :
g_signal_connect (G_OBJECT(renderer), "toggled", G_CALLBACK
(your_callback), NULL);
"your_callback" would look like this :
static void your_callback(GtkCellRendererToggle *cell,
gchar *path_str,
gpointer data)
{
// get the treemodel from somewhere
GtkTreeIter iter;
GtkTreePath *path = gtk_tree_path_new_from_string (path_str);
gboolean enabled;
gtk_tree_model_get_iter (model, &iter, path);
gtk_tree_model_get (model, &iter, COLUMN_X, &enabled, -1);
enabled ^= 1;
// do something with the new enabled value, and set the new
// enabled value in your treemodel
gtk_tree_path_free (path);
}
I don't remember where I learned this, but I think it was from the
gtk-demo though.
