Hi Phil,
I did add the SLDSelect function but I was able to draw the polygon but
nothing happens after that. This is my code,
control: new OpenLayers.Control.SLDSelect(
OpenLayers.Handler.Polygon, {
displayClass: 'olControlSLDSelectPolygon',
layers: features,
eventListeners: {
"selected": function (evt) {
//features.removeFeatures();
var pfilter = new OpenLayers.Filter.Spatial({
type: OpenLayers.Filter.Spatial.INTERSECTS,
value: evt.feature.geometry
});
var propNames = [];
//var layerNode = getLayerNode(combo.value);
var layerNode = tree.getSelectionModel().getSelectedNode();
if (layerNode !== null) {
wfsProtocol = new
OpenLayers.Protocol.WFS.fromWMSLayer(layerNode.layer);
wfsProtocol.read({
filter: pfilter,
callback: processSpatialQuery,
scope: new OpenLayers.Strategy.BBOX()
});
features.removeAllFeatures();
} else {
alert("Please select a Map Layer");
features.removeAllFeatures();
}
}
}
})
Just to make sure of one thing. When you added mylayer in layers, it was
you vector field right? The feature layer that I have added to the layers
is also my vector layer.
You can check the functioning here<http://128.196.142.12/geo/test/test1.html>.
Select the pima pine layer in the tree and Click on the draw poly tool in
the toolbar. Then draw you defined polygon on any of the blue stars. The
firebug is also not returning any errors.
Thanks,
Smaran
