Re: [Geotools-gt2-users] GT1, GT2, bit confused.

[Chris G. <cg...@gc...>]

Hello Reuben,

Thanks Reuben for the info.    I will explore all these links below.   I 
noticed the FrameTools code posted
below, might be helpful.
http://docs.codehaus.org/display/GEOTOOLS/Adding+Tools+to+a+Map
It looks like this example shows zoom in, out, and panning (and written 
by you!)...  I may approach the
application a bit for GT2 given GT2 is a heavier weight and probably 
belongs more on the server side.  See
my previous posting as to why.

I'll will be sure to update the WIKI as I move along through the 
process.  I think this is a great idea
allowing users to contribute comments, code, etc. as they learn, 
encounter, and hopefully solve
problems.

Thanks,
Chris

Yet, I'm having a difficult time finding any examples for GT2 and it appears from the mailing list intro that GT2 really shouldn't be used for applets anyway.

>>I'm sure everyone here is overworks and underpaid, so these things are attributed to that!  I'm trying to get the story straight and determine where I should put my efforts.  It seems like to me GT2 focus has change to more server side applications and maybe I'm barking up the wrong tree trying to update this applet.  I alsa noticed by compiling some of the sample applications from the WIKI that it requires JAI which I suppose would make an applet a bit heavier weight.
