Hello,
I'm new with GWT and GWT-Maps. I need to plot polylines over a Map
widget. My problem is that the polyline only shows up in Hosted mode.
When running in Web mode, I can't see it.
More detailed, there's an addRoutes() function I wrote to plot the
polylines:
private void addRoutes() {
boolean loadOK;
PolyStyleOptions pso =
PolyStyleOptions.newInstance(overlayColor,
weight, opacity);
DataLoader loader = new DataLoader();
loadOK = loader.LoadSegments(map, pso);
if(! loadOK)
Window.alert("asyncGet() failed.");
}
The LoadSegments() method of the DataLoader class tries to access
a segments.txt file, located in the module's root folder. That file
contains a list of GPS coordinates, defining the polylines.
private static final String segmentsInputPath = "segments.txt";
@SuppressWarnings("deprecation")
public boolean LoadSegments(MapWidget m, PolyStyleOptions options) {
boolean result =
HTTPRequest.asyncGet(GWT.getModuleBaseURL() + segmentsInputPath,
new MapSegmentPlotter(m, options) );
return result;
}
Finally, the MapSegmentPlotter class implements the
ResponseTextHandler interface, by overriding onCompletion(String
responseText) to draw the polylines. I don't give its code here - but
I assume that it does the job - since the polylines show up in Hosted
Mode. However, no trace of them in Web mode. Where do I go wrong ?
