Dynamic widget creation/destruction

[Russell Shaw <rjshaw iprimus com au>]

Hi,
When a bunch of widget objects are created such as in a dialog,
do they need to be destroyed to free memory before returning?
Does every widget need to be destroyed, or will destroying the
top widget automatically destroy all the child widgets? What
command to use for destroy?

static void
dialog_bg(void)
{
    GtkWidget* dialog=gtk_dialog_new_with_buttons("Grid Settings",NULL,
      GTK_DIALOG_MODAL|GTK_DESTROY_WITH_PARENT,
      GTK_STOCK_OK,GTK_RESPONSE_OK,
      GTK_STOCK_APPLY,GTK_RESPONSE_APPLY,
      GTK_STOCK_CANCEL,GTK_RESPONSE_CANCEL,
      NULL);

    GtkWidget *button=gtk_radio_button_new_with_label(NULL,"Grid");
    gtk_widget_show(button);
    GSList *group=gtk_radio_button_get_group(button);
    GtkWidget *button=gtk_radio_button_new_with_label(group,"Dots");
    gtk_widget_show(button);
    gtk_box_pack_start(GTK_BOX(GTK_DIALOG(dialog)->action_area),
                        button, TRUE, TRUE, 0);
    // run modal
    gint result=gtk_dialog_run(dialog);
