[Gwt-openlayers-users] Overview Map Options

[Philipp V. <phi...@go...>]

Greetings,

I'm trying to use an overview map with a different maplayer than shown in
the map window. But I have problems integrating the overview map layer.
Here is some code:


        // Set up the WMS which extends Layer
        WMSParams wmsParams = new WMSParams();
        wmsParams.setFormat("image/png");
        wmsParams.setIsTransparent(true);
        wmsParams.setLayers("basic");
        wmsParams.setStyles("default");
        wmsParams.setMaxExtent(new Bounds(90, 0, 120, 20));

        WMSOptions wmsLayerParams = new WMSOptions();
        wmsLayerParams.setIsBaseLayer(false);
        wmsLayerParams.setLayerOpacity(1.0);

        WMS wmsLayer = new WMS("basic", "http://labs.metacarta.com/wms/vmap0
",
                wmsParams, wmsLayerParams);

        OverviewMapOptions options = new OverviewMapOptions();
        Layer[] layers = new Layer[1];
        layers[0] = (Layer)wmsLayer;
        options.setLayers(layers);

        map.getMap().addControl(new OverviewMap(options));


Anyone knows whats wrong with the code?

Cheers,
Philipp
