first thanks for the reply

using your code the canvas doesn't show up. it starts with =
width=3D=3Dheigth=3D=3D1.=20
but it will show up when setting LAOUT_FILL_X/Y.
you got to connect a sel_map with the glcanvas to set LAYOUT_FIX_X/Y =
later.

but unfortunately this doesn't solve my problem.=20
the scrollwin still doesn't scroll the much larger dummy containing a =
glcanvas.

maybe i write a *little* demonstration script next week to show the =
problem.

have a nice weekend,
