Hello, I'm trying to use a JMapPane to display some data, but I get nothing. I
haven't found a jmappane example and so I'm just guessing how to use it, the
code I've written is this :
PostGISConnectionDialog pgis_dialog = new
PostGISConnectionDialog(this); // modal window to input postgis connection
properties.
PostGISProperties pgis_properties = pgis_dialog.getProperties();
// PostGISProperties keeps hostname, port, username, etc.
try {
PostGISReader pgis_reader = new PostGISReader(pgis_properties);
// PostGISReader provides easy access to the postgis database.
FeatureCollection feature_collection =
pgis_reader.getFeatures();
StyleFactory style_fact =
CommonFactoryFinder.getStyleFactory(null);
Style style1 = style_fact.getDefaultStyle();
CoordinateReferenceSystem crs = pgis_reader.getCoordRefSystem();
MapContext map_context = (MapContext)new DefaultMapContext(crs);
map_context.addLayer(feature_collection, style1);
GTRenderer gt_renderer = (GTRenderer)new StreamingRenderer();
map_pane = new JMapPane(gt_renderer, map_context);
jPanel1.add(map_pane, BorderLayout.CENTER);
this.validate();
} catch (IOException e) {
JOptionPane.showMessageDialog(this, "Could not access the
database.", "Error",JOptionPane.ERROR_MESSAGE);
}
PostGISReader.getFeatures() and PostGISReader.getCoordRefSystem() return
correct values, i have tested this. So, I must be doing something really wrong
:) Any help is welcome :)
