+
+	Issue 265.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/FloodMap.java:
+	  Added method to activate/deactivate scale line. The method removes the
+	  control on deactivation and adds the control on activation.
+
+	* src/main/java/de/intevation/flys/client/client/ui/map/MapOutputTab.java:
+	  Implements TabSelectedHandler now. If the tab is selected, the scale line
+	  and measure control are deactivated. Scale line is activated if the tab is
+	  selected.
