Close root_window

[Iker Perez de Albeniz <ialbeniz cbt es>]

Hi,

I haver created my own widget with some images+evenBox. What i want to
do is to hide,minimize and maximize the window where the widget is
contained..

i have tried to do:

	Glib::RefPtr<Gdk::Window> window = this->get_window();
	Glib::RefPtr<Gdk::Window> window2 = window->get_parent(); 
	window2->hide();

but it breaks with a "Segmentation Fault"

With..

	Glib::RefPtr<Gdk::Window> window = get_root_window(); 
	window->hide();

compiles Ok but when i execute dont do anything...	

it hapends the same with iconify(), maximize() or move(x,y) functions..

any idea how to do it??
