Hi Sorry about yesterdays rant.
If you have not lost all patients with me, I would really appreciate it if anyone could tell me how I get the x, y coordinates of the drop from my IDropAction class. Thanks Michelle -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of M.S.Bachler Sent: 13 March 2006 11:04 To: User-friendly Desktop Internet GIS Subject: RE: [udig-devel] Shapefiles Hi! Thanks everyone for your various inputs. I am still not sure what I am doing (I have decided I am just thick!). I can't see how the DataUtility way or creating a FeatureType passes in the x,y of the point. Then again, I can't even figure out how I get the x, y coordinates of the drop from my IDropAction class in order to create the coords for my Point class in the first place? I have run around the API, but can't figure it out. Is there really no example code out there that I can study to help me understand things better. I am unable to download the source code with Subversion (I did write to the list about this but no one replied). I need the equivalent of "uDig for Dummies" book. Being a Java developer for many years I thought this project would be relatively easy. But I think having no familiarity with Eclipse or GIS at all, has really not helped me. While Eclipse is becoming more familiar, 'GIS speak' is still a mistery. I think what seems obvious to many of you when talking about the code, just escapes me. I know people are reluctant to spoon feed me the code I need. I know I need to go through the pain barrier and try and understand it all myself. But it really hurts, and for various reasons the timescale of my project has been shrunk, and I am in danger (for the first time in my lief!), of not completing something, and having to say I can't do it. I think I have just not reached that eureka moment, when everything suddenly clicks into place. I hope it happens soon! I still have a head full of floating jigsaw pieces. Meanwhile, if someone could help me with how I get the x,y of the drop, that would be great.
