Hi Michael,
This does not quite work because the the compiler is unable to locate
the newly defined method in the anonymous subclass. But, creating a
named subclass of DefaultMapLayer with your dataChanged method does
work.
You have to override all of the constructors in DefaultMapLayer, s
Hi again Luong,
I'm just learning about this stuff myself...
The programmatic way of drawing a green line would look like this...
SimpleFeatureType type = ...
StyleFactory factory = CommonFactoryFinder.getStyleFactory(null);
StyleBuilder sb = new StyleBuilder(factory);

Hi Luong,
I don't think you should study that example because things have
changed, and are changing, so much that it will just make it all more
confusing.
For simple stuff (which is a
Greg,
Could you test this for me please ?
// instead of myMapContext.addLayer( myGrid, myStyle ) do this...
//
MapLayer myGridLayer = new DefaultMapLayer(myGrid, myStyle) {

sourceListener.changed(null);
}
I see, in the example code, which i know is out of date, but it gives me a
starting block for learning this,

sb.createRule(ls2)));

Ah, good question
M,
thanks for the code. in it you say:
vertices[k++] = new Coordinate(x, y);
where x and y are of type double. however, since my gps gives me data
in the form of 144 12.345 where the 144 is degrees and the 12.345 is
minutes, how do i create coordinates if the constructor takes doubles?
O
Sure thing.
Do you have commit privileges to the geotools codebase?

Ciao Simone,
Actually that would be very useful for me. Perhaps I could email you
some code in the next week or two ?

Hi
The general idea is that using a Rule you can control how to render the
feature.
A Rule has a condition.If the condition is satisfied the Symbolizer defined
under the rule hold good, so the feature will be drawn based on those
symbolizers. The condition can either be a Filter or Scale value.
Hi i was reading the page http://docs.codehaus.org/display/GEOTDOC/05+Style
about styles. Would somebody kindly explain the purpose of having a rule and
what relationship it has with the sysmbolizers, because i don't really
understand what it is saying concerning the rules.
Thanks

As far as I remember MapContext should not be thread safe, however if
the access it read only, yo should be good to go.

Hi,
I have a JMapPane displaying a MapContext containing a number of
layers. I modify one of these layers via
WritableRandomIter.setSample(x, y, b, value). When I pan or zoom, the
changes appear. Is there some way that I can force the changes to
appear programmatically?
Thanks!
Greg
Hey,
Generally, the getMap request is all in the URL so you merely need to
parse that. It's the stuff after the '?' in key value pairs. Are you
looking for code in GeoTools that does that for you? I don't know of any
off the top of my head.
The request could also be sent in the body of a message
Hi all,
I am trying to intercept a user WMS getMap request in a servlet filter, and
I would like to parse it into a GetMapRequest
(org.geotools.data.wms.request.GetMapRequest) object so that I can after
that use its functions.
Are there some parser that can do the job passing the HttpServletReques
