annotate flys-artifacts/src/main/java/de/intevation/flys/artifacts/math/Distance.java @ 4329:c9dcce9448f2
Added a new control 'show legend' to the map's toolbar. This control opens a window that displays the legends of all activated layers.
Currently, the row in that window has a fixed size of 400x150. The size is fixed, because there are problems with SmartGWT to build
panels with auto height/width :-/
