[Geomoose-users] configuring scaleLine.js

[Brent Fraser]

Bob,

I copied the code from v2.4's main.js:

     if(CONFIGURATION.scale_line.enabled) {
         Map.addControl(new OpenLayers.Control.ScaleLine({
             bottomOutUnits: CONFIGURATION.scale_line.bottom_units,
             topOutUnits: CONFIGURATION.scale_line.top_units,
             maxWidth: CONFIGURATION.scale_line.width
         }));
     }

and pasted it into v2.6.1's build\dojo\dojo.js (yes, I know that is not 
the right way) just before "this.configureMapTools();":


     if(CONFIGURATION.scale_line.enabled) {
         Map.addControl(new OpenLayers.Control.ScaleLine({
             bottomOutUnits: CONFIGURATION.scale_line.bottom_units,
             topOutUnits: CONFIGURATION.scale_line.top_units,
             maxWidth: CONFIGURATION.scale_line.width
         }));
     };

this.configureMapTools();

(You should really put this in Application.js and do a dojo compile.)

But it did show the OpenLayers scale bar in v2.6.1:
