Hi all,
Is it possible to show non-Geoserver defined styles in the LegendPanel? (sld
file is non existent)
For a layer straight out of Geoserver this is no problem, I understand the
corresponding sld is consulted to define the entry in the lgend.
I have a query facility where the user specifies on the fly which attributes he
would like to see in a given layer, and how he would like them styled (color,
radius etc.).
The layers display fine on the map and in the layer tree, but I would like to
add a corresponding entry in the legend panel. At present only the layerName
shows, but no icon(s).
Some code extracts are included below.
Any tips or hints would be gratefully received,
Thanks,
Eoin
An extract from the code used to specify the style parameters for the layer is
as follows:
queryLayer.mergeNewParams({
sld_body: new OpenLayers.Format.SLD().write({
namedLayers: [{
name: panel.selectedLayer.get("name"),
userStyles: [style]
}]
})
});
map.addLayer(queryLayer);
The user's style is constructed as follows:
style = new OpenLayers.Style("", {rules: [
new OpenLayers.Rule({
title: "generic point rule",
filter: panel.getFilter(), //append the
criteria specified by the user (attributes + their values)
symbolizer: {
"Point": {
pointRadius:
hilightsize, // user defined
graphicName: "circle",
fillColor:
hilightcolor, // user defined
fillOpacity: 0.75,
strokeWidth: 1,
strokeOpacity: 0.75,
strokeColor: "#000000"
}
}
})
]//close rules array
}); //close var definition
