Dear Steve,
CoordMouseMode is a base class for other MouseModes (NavMouseMode,
SelectMouseMode, etc)
What I did in my code? Subclassed every mouse mode I use and overrided
method createCoordinateInformationLine().
class MyNavMouseMode extends NavMouseMode {
public MyNavMouseMode(){
this(true);
}
protected String createCoordinateInformationLine(int x, int y,
LatLonPoint llp) {
if (llp != null) {
return InfoLineFormatter.formatUTM(llp);
} else {
return InfoLineFormatter.formatXY(x, y);
}
}
}
You have to add this new mousemode to openmap.properties instead of original
one (put full package and class name).
InfoLineFormatter class has simple static methods which return String value
displayed in InformationDelegator status line.
Example of UTM formatting:
class InfoLineFormatter {
private static DecimalFormat myFormat = new DecimalFormat("###.##");
public static String formatUTM(LatLonPoint llp) {
// convert lat lon to UTM
UTMPoint utmPoint = new UTMPoint(llp);
// format UTM coordinates
StringBuffer sb = new StringBuffer(32);
sb.append(Integer.toString(utmPoint.zone_number));
sb.append(String.valueOf(utmPoint.zone_letter));
sb.append(' ');
sb.append(myFormat.format(utmPoint.easting));
sb.append(' ');
//Locale
sb.append(myFormat.format(utmPoint.northing));
return sb.toString();
}
}
Hope this will help you.
Don,
I think about adding new OpenMap component similar to presented
InfoLineFormatter, but added to BeanContext.
CoordMouseMode (and maybe other MouseModes too) could call its methods to
obtain formatted line. Existance in BeanContext allows changing of
InfoLineFormatter implementation, even at run-time (e.g. user selects he/she
wants now UTM coordinates displayed instead of LatLon). What do you think?

Piotr Kaminski
