Thank you John.
I solved looking in the FAQ! It was only that I have to use
self.area.set_events(gtk.gdk.POINTER_MOTION_MASK)
instead of
self.area.set_events(gtk.gdk.POINTER_MOTION_MASK |
gtk.gdk.POINTER_MOTION_HINT_MASK )
Thanks a lot.
Now I have another question that I can't solve.
While I can draw a line on a gtk.gdk.Drawable object, it looks that I
cannot delete it. For example I can draw a line using:
area = gtk.DrawingArea()
area.window.draw_line(gc, x1, y1, x2, y2)
but I cannot delete such line... a line isn't identified by an object or
an ID and it doesn't exist a proper method to delete it!
Is there a trick to solve this trouble?
Thanks again.

Hi,
I don't know if this is the solution but it sounds similar to a problem
that I had. I had a gtk.Image inside a viewport inside a scrolling
window. In order to capture the 'motion-notify-event' on my gtk.Image, I
needed to add an EventBox on the image, and capture the events to that.
I used Glade to do that, and it worked fine. Have you tried an EventBox yet?
There was something in the PyGTK FAQ about this.
Cheers
JP
