I've distilled my code down to a standalone program. Hopefully now
someone else will easily be able to play with it and see what's wrong.
FWIW I'm using libgtk+ 2.8.6 from Ubuntu Breezy. Same problem on x86 and
x86_64.
#include <gtk/gtk.h>
#define N_ITEMS 10
#define USE_SCROLL 1
static void destroy_handler(GtkObject *o, void *d)
{
gtk_main_quit();
}
enum {
Column_Radio,
Column_Name,
Column_NColumns
};
static void populate_list(GtkListStore *list)
{
int n;
for (n = 0; n < N_ITEMS; ++n)
{
GtkTreeIter iter;
char *s = g_strdup_printf("Item %d", n);
gtk_list_store_append(list, &iter);
gtk_list_store_set(list, &iter,
Column_Radio, n == 1,
Column_Name, s,
-1);
g_free(s);
}
}
static GtkWidget *create_list_widget(void)
{
GtkTreeViewColumn *rcolumn, *tcolumn;
GtkCellRenderer *radio;
GtkWidget *widget;
GtkTreeView *tvw;
GtkListStore *list;
widget = gtk_tree_view_new();
tvw = GTK_TREE_VIEW(widget);
list = gtk_list_store_new(Column_NColumns,
G_TYPE_BOOLEAN, G_TYPE_STRING);
gtk_tree_view_set_model(tvw, GTK_TREE_MODEL(list));

gtk_cell_renderer_toggle_set_radio(GTK_CELL_RENDERER_TOGGLE(radio), TRUE);

gtk_container_add(GTK_CONTAINER(main_win), tvw);
#endif
gtk_widget_show_all(main_win);
gtk_main();
return 0;
}
