Convert GtkWindow to GdkDrawable

["Laurent Houdusse" <l houdusse free fr>]

My window object is a GtkWidget so how to convert GtkWidget to GdkWindow?
What is the link between GTK library and GDK library?
See my code:

GtkWidget *window;
        
gtk_init (&argc, &argv);
window = gtk_window_new(GTK_WINDOW_TOPLEVEL); 
gtk_window_set_position(GTK_WINDOW(window),GTK_WIN_POS_CENTER); 
gtk_window_set_default_size(GTK_WINDOW(window),500,300);
        
HWND hwnd = GDK_WINDOW_HWND(GDK_DRAWABLE(window));

gtk_widget_show_all(window);

I have a message: invalid cast from 'GtkWindow' to 'GdkDrawable'

You can get the window handle of a GdkWindow with

#include <gdk/gdkwin32.h>

  ...
  GdkWindow *window;
  ...
  HWND hwnd = GDK_WINDOW_HWND (window);
