It's not a glade problem. The traceback is correct, gtk.DrawingArea

When the application is realized, you'll be passed at gtk.DrawingArea
widget. The window attribute of that widget is a gtk.gdk.Drawable.
Here is a simple example that illustrates how to draw.
Note the use of widget.window to get the gtk.gdk.drawable.
JDH
import pygtk
pygtk.require('2.0')
import gtk
from gtk import gdk
def draw(widget):
gc = widget.window.new_gc()
gc.line_style = gdk.LINE_ON_OFF_DASH
gc.set_dashes(0, [6,6])
x = range(0,100,2)
y = [2*val for val in x]
widget.window.draw_lines( gc, zip(x, y) )
def configure_event(widget, event):
draw(widget)
return gtk.TRUE
def expose_event(widget, event):
draw(widget)
return gtk.TRUE
win = gtk.Window()
win.set_size_request(100, 200)
win.show()
vbox = gtk.VBox()
vbox.show()
win.add(vbox)
da = gtk.DrawingArea()
da.connect('configure_event', configure_event)
da.connect('expose_event', configure_event)
da.show()
vbox.pack_start(da, gtk.TRUE, gtk.TRUE)
button = gtk.Button('Quit')
button.show()
vbox.pack_start(button, gtk.FALSE, gtk.FALSE)
button.connect('clicked', gtk.mainquit)
gtk.mainloop()
