SWTMapFrame

The following is a tutorial that explains how to use the gt-swt module in standalone mode and inside an RCP environment. The tutorial assumes the user is already confident with GeoTools development/build and already an basic RCP developer.

Example

Using the standalone gt-swt module is fairly easy.

1. It is best explained with a code snippet:

   public class Main {
      public static void main( String[] args ) throws Exception {
       // create a default mapcontext
       MapContext context = new DefaultMapContext();
       // set the title
       context.setTitle("The SWT Map is in the game");
       // add a shapefile if you like
       File shapeFile = new File("/home/moovida/data/world_adm0/countries.shp");
       ShapefileDataStore store = new ShapefileDataStore(shapeFile.toURI().toURL());
       SimpleFeatureSource featureSource = store.getFeatureSource();
       SimpleFeatureCollection shapefile = featureSource.getFeatures();
       context.addLayer(shapefile, null);
   
       // and show the map viewer
       SwtMapFrame.showMap(context);
      }
    }
   

   Which results in:

   

2. It is possible to tweak some of the window settings, like statusbar, layers panel and toolbars/menus. For this use we have to move beyond our call to SwtMapFrame.showMap(context)

   The result is equally easy. Again a code snippet is the best way.

   In the following case we decide that we want to get rid of the layers panel:

   boolean showMenu = true;
   boolean showToolBar = true;
   boolean showStatusBar = true;
   boolean showLayerTable = false;
   final SwtMapFrame frame = new SwtMapFrame(showMenu, showToolBar, showStatusBar, showLayerTable, context);
   frame.setBlockOnOpen(true);
   frame.open();
   

   Which results in:
