net.simplace.ui.formengine.geotools.MapPointsChooserPanel

Version: 1.0

This class provides javax.swing.JPanel which shows several map layers and let the user choose some points. After each selection the point is marked in a special top layer. The current selection can be accessed by getSelection() and maintained by clearSelection() and undoSelection().

Informations about map control:

Zoom-in: mouse wheel or left drag
Zoom-out: right click or mouse wheel
Move map: right drag
Point selection: left click

public static final Class SELECTION_GEOMETRY_TYPE;

// Protected Instance Methods

protected void performSelectTool(); // Overrides GeoObjectChooserPanel

Sets the map action tool to net.simplace.ui.formengine.geotools.MapPointsChooserPanel.MAPPOINTCHOOSE_TOOL.

protected Class getGeometryType(); // Defines AbstractMapChooserPanel

Returns the geometry typ used to visualize an selection com.vividsolutions.jts.geom.Point.

protected Geometry transformSelectionObjectToGeometry(Coordinate aCoord);
// Defines AbstractMapChooserPanel

Creates a com.vividsolutions.jts.geom.Geometry from an com.vividsolutions.jts.geom.Coordinate. If aCoord is null, a default (dummy) geometry is generated.

aCoord the {@link Coordinate} of one selection

protected Style getSelectionStyle(Color aSelectionColor);
// Defines AbstractMapChooserPanel

Returns the style used to visualize a selection com.vividsolutions.jts.geom.Point.

aSelectionColor the color the style is created with (not used at the time!)

protected void performSelectionEvent(int x, int y);

Performs a point selection on the map. Adds the point to position 0 of the net.simplace.ui.formengine.geotools.MapPointsChooserPanel.iSelectionObjectspoint list, transforms it to a org.opengis.feature.Featurepoint feature and stores it in the net.simplace.ui.formengine.geotools.MapPointsChooserPanel.iSelectionFeatureCollectionFeatureCollection, as well as in the net.simplace.ui.formengine.geotools.MapPointsChooserPanel.iSelectionFeaturesmapping.
