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)
