net.simplace.ui.formengine.geotools.GeoObjectChooserPanel
Version: 1.0
This class provides de.schmitzm.swing.JPanel which shows several map layers and
let the user choose a geo object from one specific layer.
The selection result is provided by getSelectionResult() and depends
on, whether a raster or a feature layer is set as selection layer
(by setSelectionLayer(int)).
The panel can be used to choose only one object (raster value or single
org.opengis.feature.Feature) by single click or multiple objects (subset org.geotools.coverage.grid.GridCoverage2D or
org.geotools.feature.FeatureCollection) by window selection. Use the setMultiSelectionEnabled(boolean)
method to switch between these options. The default is false (only single
selection).
The value ( double, org.geotools.coverage.grid.GridCoverage2D, org.opengis.feature.Feature, org.geotools.feature.FeatureCollection
selected by the user is provided by the getSelectionResult() method; the
selected range by getSelectionRange().
Informations about map control:
- multi selection enabled:
- Zoom-in: left click or mouse wheel
- Zoom-out: right click or mouse wheel
- Move map: right drag
- Selection: left drag
- multi selection disabled:
- Zoom-in: left drag (window selection)
- Zoom-out: right click or mouse wheel
- Move map: right drag
- Selection: left click
In addition to the map, the panel contains a de.schmitzm.geotools.gui.MapPaneStatusBar to
show the geo coordinates and the raster value the mouse moves over. In
contrast to the default de.schmitzm.geotools.gui.MapPaneStatusBar, not the raster values of
the upper visible layer are shown, but of the selection layer always.

visualization tool bar.
returns the selected tool
public SelectableXMapPane getMapPane();

public
FWAtlasMapPanel getAtlasPanel();
returns the {@link FWAtlasMapPanel} the layer are displayed in.
public MapContext getMapContext();
returns the {@link MapContext} the layer can be put in.
public MapLayer getSelectionLayer();
Returns the layer the selection is made on.
returns {@code null} if no selection layer is specified yet
public void
setSelectionLayer(MapLayer aLayer);
Sets the layer the selection is made on.
- aLayer a layer of the map's context
public void
setSelectionLayer(int aLayerIdx);
Sets the layer the selection is made on.
- aLayerIdx the index (top to bottem) of a layer
public void
setMultiSelectionEnabled(boolean aMultiSelection);
Sets whether the dialog can be used to choose more than one object.
public boolean isMultiSelectionEnabled();
returns Checks whether the dialog can be used to choose more than one object.
public Object
getSelectionResult();
Returns the geo object(s) of the last user selection. Returns
- a single double value, if multi selection is disabled and the
selection layer is a raster layer.
- a single Feature, if multi selection is disabled and the
selection layer is a vector layer.
- a subset GridCoverage2D, if multi selection is enabled and the
selection layer is a raster layer.
- a FeatureCollection, if multi selection is enabled and the
selection layer is a vector layer.
returns {@code null} is no selection layer is specified or no selection if performed yet
public Object
getSelectionRange();
Returns the bounds of the last user selection. Returns
- a java.awt.geom.Point2D with map coordinates, if multi selection is disabled.
- a com.vividsolutions.jts.geom.Envelope with map bounds, if multi selection is enabled.
returns {@code null} is no selection layer is specified or no selection if performed yet
public void performMapPaneEvent(XMapPaneEvent e); // From
de.schmitzm.geotools.map.event.JMapPaneListener
Performs the map actions (selection) initiated by the user.
// Protected Instance Methods protected void initializeMaps();
initializes the Maps in GeoObjectChooser
protected void performSelection();
Is called after a selection is made. Does nothing. Sub classes can
override this method to react on selections individually.
