label_box = Gtk::HBox.new(false, 0) 
label = Gtk::Label.new('Page1') 
label_box.pack_start(label, false, false, 0) 

btn = Gtk::Button.new 
btn.relief = Gtk::RELIEF_NONE 
btn.focus_on_click = false 
style = btn.modifier_style 
style.xthickness = 0 
style.ythickness = 0 
btn.modify_style(style) 
btn.set_tooltip_text("Close page1") 
wim,him = Gtk::IconSize.lookup(Gtk::IconSize::MENU) 
btn.set_size_request(wim+2,him+2) 
btn.signal_connect('clicked') do 
  $notebook.remove_page($notebook.children.index(treeview)) 
  store.clear 
  label_box.destroy 
  treeview.destroy 
end 

image = Gtk::Image.new(Gtk::Stock::CLOSE, Gtk::IconSize::MENU) 
btn.add(image) 

align = Gtk::Alignment.new(1.0, 0.0, 0.0, 0.0) 
align.add(btn) 
label_box.pack_start(align, false, false, 0) 

label_box.spacing = 3 
label_box.show_all 

page = $notebook.append_page(treeview, label_box) 
treeview.show_all 
$notebook.page = $notebook.n_pages-1
