[geotk] First try with geo-tk. Display a map with Shapefile

[Arnaud Vandecasteele]

Hi all,


I'm "playing" with geo-tk and I'm trying to display a map which
contains a Shapefile.
I've almost succeed to do what I want but my data are not visible on the map.

Did I miss something ?
If you could have a look on my code it will be great.

Thanks for your help

Best regards

Arnaud
