| GeoMouseEvent | | final public class GeoMouseEvent extends MouseEvent (Code) | | A MouseEvent which contains methods to obtain coordinates in real world
CoordinateSystem as well as Screen Coordinates.
All
MouseListener s that have registered for
org.geotools.gui.swing.MapPaneImpl mouseEvents will receive
events of this class.
Listeners implementations can implements their code as below:
public void mouseClicked(MouseEvent e) {
GeoMouseEvent event = (GeoMouseEvent) e;
// Process event here...
}

| GeoMouseEvent | | public GeoMouseEvent(MouseEvent event, MathTransform transform)(Code) | | A mouseClick event which also contains methods to transform from
pixels to the Coordinate System of the Renderer.
Parameters:
event - The original mouse event.
Parameters:
transform - The transform which will convert screenCoordinatesto CoordinateSystem coordinates. |
| getMapCoordinate | | public GeneralDirectPosition getMapCoordinate(GeneralDirectPosition dest) throws TransformException(Code) | | Returns the "real world" mouse's position. The coordinates are expressed
in Context's CoordinateSystem.
Parameters:
dest - A pre-allocated variable to store the mouse's locationin CoordinateSystems, can be set to null. The mouse's location in CoordinateSystem coordinates.
throws:
TransformException - when transform is invalid. |
