net.simplace.ui.formengine.geotools.MapAreaChooserPanel

Version: 1.0

This class provides de.schmitzm.swing.JPanel which shows several map layers and let the user choose some envelopes. After each selection the envelope is marked in a special top layer. The current selection can be accessed by getSelection() and getSelectionAsRectangle2D() and maintained by clearSelection() and undoSelection().

Informations about map control:

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

Returns (a copy of) the list of the selected envelopes.
returns the rectangle2d selection

// Protected Instance Methods

protected void performSelectTool(); // Overrides GeoObjectChooserPanel

Sets the map action tool to net.simplace.ui.formengine.geotools.MapAreaChooserPanel.MAPAREACHOOSE_TOOL.

protected Class getGeometryType(); // Defines AbstractMapChooserPanel

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

protected Geometry transformSelectionObjectToGeometry(Envelope aEnv);
// Defines AbstractMapChooserPanel

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

aSelectionObject the object of one selection

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

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

aSelectionColor the color the style is created with

protected void performSelectionEvent(int ox, int oy, int px, int py);

Performes a envelope selection on the map. Adds the envelope to position 0 of the net.simplace.ui.formengine.geotools.MapAreaChooserPanelenvelope list, transforms it to a Feature polygon featurepolygon feature and stores it in the net.simplace.ui.formengine.geotools.MapAreaChooserPanel.iSelectionFeatureCollectionFeatureCollection, as well as in the net.simplace.ui.formengine.geotools.MapAreaChooserPanel.iSelectionFeaturesmapping.

ox start position in window coordinates
oy start position in window coordinates
px end position in window coordinates
py end position in window coordinates
