 Hi, 

 First, 
	 #include <gdk/gdkx.h>
 And then use
	GDK_DISPLAY()
 to X display your program runs on.

 Drawable is also X primitive (either pixmap or window id), acquire it
	GDK_WINDOW_XWINDOW(gdkwindow)
 i.e. parmater 'gdkwindow' should be of type GdkWindow. To get GdkWindow from
 GtkWidget, do
	GTK_WIDGET(widget)->window
 So, to get Drawable from GtkWidget widget:
	GDK_WINDOW_XWINDOW(GTK_WIDGET(widget)->window)
