Re: Gdk window

[günther <guenther rapp-informatik de>]

As I under Know
you need a top level window first
than fo your Drawing window you need child type container
 i do not know if GdkDrawable is such typ 
      main_window
              container
                  drawable

also you need a gtk_main() loop else happens noting.
I thing the the seg fault is in the gdk_window_new call.
This call should have only one parameter

I suggest  for starting.
       Take   glade as a graphical interface to gtk 
        make very small samples an let generate the code by glade
          have a look on that code to see what can be done.
         Glade generates a lot of code normaly no neccessary in all
            applications
  here is short glade starting code
