Re: [udig-devel] Help with simple plugin
|
Hey Cory,
thanks a lot for your info, this tutorial helped me a lot :).
I´m still fighting but am starting to understand a bit. I dont know,
but I´m finding uDig a little bit too complex. I just want to add a
layer to the map, and I seem to have to implement a lot of classes to
do that :( .
Does anyone know if are there some (UML?) diagrams to help me
understanding the big picture? I couldnt find any (neither on the site
nor searching on Google). Or maybe some docs on this inter-relation
between the classes/interfaces like Map, Layer, Feature, FeatureType,
etc.
Thanks,
-Pedro Da Ros

Pedro,
I've written a crude tutorial here:
http://svn.geotools.org/udig/community/chorner/net.refractions.udig.tutorials.txtDataStore/
but haven't had time to clean it up or document it well. It may help
you out though, as it does successfully read points in from an ascii
file (i believe the format was x,y one per line.
Cheers,
Cory.
