Re: [Geotools-gt2-users] Problem with the Select Tool to select a LineSymbolizer

[Manu_macros <mac...@gm...>]

Hi,
I use the 2.3.3 version, as it's recommended in the geotools website.
But I have resolved the problem. In fact the selection of the LineSymbolizer
not worked because of the filter used (in the JMapPane) : it search the
point click mouse CONTAINS a geometry. It couldn't work because the
lineSymbolizer is to small (series of points) to have the click right in the
line. So I have done a distance filter which look a litlle around the mouse
click.
I put it here if someone has the same problem
[code]
public static Filter polygonIntersectPoint(FeatureSource source, double x,
double y){
		// create a filter
		FilterFactory filterFactory = FilterFactoryFinder.createFilterFactory();

		// look up geometry attribute name used for testing
		//
		String geometryName = source.getSchema().getDefaultGeometry().getName();

		// Create the attribute expression
		AttributeExpression geometryExpression =
filterFactory.createAttributeExpression(geometryName);
		
		// Create the point used
		Coordinate pointCoordinate = new Coordinate(x,y);
		GeometryFactory geometryFactory = new GeometryFactory();
		com.vividsolutions.jts.geom.Point pt =
geometryFactory.createPoint(pointCoordinate);
		
		// Create the literal expression
		LiteralExpression pointExpression =
filterFactory.createLiteralExpression();
		pointExpression.setLiteral(pt);

		// create the actual test
		//
		GeometryDistanceFilter filter =
filterFactory.createGeometryDistanceFilter(Filter.GEOMETRY_DWITHIN);
		filter.setDistance(5);
		filter.addLeftGeometry(geometryExpression);
		filter.addRightGeometry(pointExpression);

		return filter;

	}
[/code]
