Emitting destroy signal

[Russell Shaw <rjshaw netspace net au>]

Hi,
I made a composite widget (Table) that inherits from GtkVbox.
I packed this into a GtkWindow in main.c When the "exit" button
is clicked in the Table widget, on_exit_clicked is called (in table.c),
which emits "destroy_event":

static void
on_exit_clicked(GtkWidget *button, gpointer data)
{
    Table *table=(Table*)data;
    g_signal_emit_by_name(table,"destroy_event",0/*detail*/,NULL);
}


In main.c, i have:


static gboolean
destroy_cb(GtkWidget *widget, GdkEvent *event, gpointer user_data)
{
    gtk_widget_destroy(widget);
}
.
.
main()
{
...
  GtkWidget *window=gtk_window_new(GTK_WINDOW_TOPLEVEL);
  Table *table=table_new();
  gtk_container_add(GTK_CONTAINER(window),table);
  g_signal_connect(table,"destroy_event",G_CALLBACK(destroy_cb),window);
...
}


When the exit button in the table widget is clicked, the table widget
is destroyed, but its parent container (a GtkWindow) remains. How do
i get that to be destroyed too?
