Hi Gopal
Suppose you have a class VisADTest. The following
codes could help you what you need.
public class VisADTest implements DisplayListener{
DisplayImpl display;
float lat,lon;
//codes....................
public void displayChanged( DisplayEvent de )
{
if (de.getId() == DisplayEvent.MOUSE_PRESSED_CENTER) {
DisplayRenderer dr = display.getDisplayRenderer();
lat = (float)dr.getDirectAxisValue(RealType.Latitude);
lon = (float)dr.getDirectAxisValue(RealType.Longitude);
}
}
// codes.....
}// end of class
Cheers
