net.simplace.ui.formengine.geotools.MapObjectChooserPanel
Version: 1.0
This class provides a javax.swing.JPanel which shows several map layers and
let the user choose a feature. The current selection can be accessed by
getSelection().
Informations about map control:
- Zoom-in: mouse wheel
- Zoom-out: right click or mouse wheel
- Move map: right drag
- Envelope selection: left drag
public class MapObjectChooserPanel extends AbstractMapChooserPanel {
// Public Constructors
public MapObjectChooserPanel(Element aFormElement, FWObservable aObservable);
// Protected Instance Variables
protected Class iSelectionGeometryType;
// Protected Instance Methods protected SimpleFeatureType
createSelectionFeatureType();
// Defines AbstractMapChooserPanel
Does not create a org.opengis.feature.type.FeatureType (as the overridden method does), but
instead returns simply the org.opengis.feature.type.FeatureType of the selection laye.
protected Class
getGeometryType();
// Defines AbstractMapChooserPanel
Returns the geometry typ used to visualize an selection com.vividsolutions.jts.geom.Envelope.
protected Geometry
transformSelectionObjectToGeometry(SimpleFeature aFeature);
// Defines AbstractMapChooserPanel
Returns the com.vividsolutions.jts.geom.Geometry of a Feature.
If aFeature is null, a default geometry is generated.
- aFeature a selected Feature
protected Geometry
transformSelectionObjectToGeometry(Envelope aEnv);
Creates a com.vividsolutions.jts.geom.Geometry from an com.vividsolutions.jts.geom.Envelope.
If aEnv is null, a default (dummy) geometry
is generated.
- aEnv
- aSelectionObject the object of one selection
returns the transformed geometry
protected SimpleFeature
transformSelectionObjectToFeature(SimpleFeature
aSelectionObject);
// Defines AbstractMapChooserPanel
Simply returns aSelectionObject.
- aSelectionObject the object of one selection
protected Style
getSelectionStyle(Color aSelectionColor);
// Defines AbstractMapChooserPanel
Returns the style used to visualize a selection object.
- aSelectionColor the color the style is created with
protected void
performSelectTool();
// Overrides GeoObjectChooserPanel
Calls the super-method and sets the mouse actions for click and window to
de.schmitzm.geotools.gui.SelectableXMapPane.SELECT_ALL.
protected void
performSelection();
// Overrides GeoObjectChooserPanel
Called when a Feature was selected on the map. If more than one
object was selected, all selected Features are added to the selection.
