:( This technique don't resolve my problem because I can't destroy the
original widget_draw.
Well, in my application, this means the user has the responsability to
create the apropiate widget_draw with or without scrollbars from the
beginning.

Thanks.

This is not really possible. But sometimes there are tricks:

I ran into a similar problem a couple of months ago.

You can get pretty close by making the initial window scrollable, but
by making the draw size a little smaller (approximately 4 pels on Mac
OS X) so that the scroll bars don't show up. Later when you make the
draw area bigger, the scroll bars appear. I had to play with it a
while to get it to work and it never worked perfectly, but got pretty
close.
