Hello Geoffrey,<div><br></div><div>Thanks a lot for your comments but my problem is exactly at destroying the legend printing for the vector layers. I have no idea on how to do this. I have tried the following but without success:</div>
<div><br></div><div><div>beforeprint: function(printProv, printMap, printPages, printOpt){</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>var includeLegend = Ext.getCmp('includeleg').getValue();</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>if (includeLegend == true){</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>var legOpt = printOpt.legend;</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>var legLayerStore = legOpt.layerStore;</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>legLayerStore.each(function(layerRec){</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>var layerDef = layerRec.get('layer');</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>if (layerDef.ClASS_NAME == 'OpenLayers.Layer.Vector'){</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>legLayerStore.remove(layerRec);</div>
<div><span class="Apple-tab-span" style="white-space:pre"> </span>}</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>})</div><div><span class="Apple-tab-span" style="white-space:pre"> </span>}</div>
<div>}</div><div><br></div><div>So my question would be, how can i tell the printprovider to not print the legend for this type of layers?</div><div><br></div><div>Thanks a lot,</div><div>Hugo</div><br><div class="gmail_quote">

Hi!<br>
<br>
I would rather use the "beforeprint" or the "beforeencodelayer" function<br>
from the "printProvider" class. This function allows you to change some<br>
parameters before layers are printed. So, trough this function, you can<br>
test if your map contains vector layers. In this case, you can probably<br>
find a way to destroy their relative legend from the print process. You<br>
will find below an example:<br>
<br>
printProvider = new GeoExt.data.PrintProvider({<br>
method: 'POST', // 'POST' recommended for production use ('GET' for<br>
development)<br>
capabilities: printCapabilities, // from the info.json script in the html<br>
listeners:{<br>
beforeprint: function(){<br>
// test each layer<br>
// if the layer is vector, remove it from the printed legend<br>
}, // or use the "beforeencodelayer" function<br>
beforeencodelayer: function (printProvider, layer){<br>
// test each layer (easy with the layer parameter provided by this<br>
function!)<br>
// if the layer is vector, remove it from the printed legend<br>
}<br>
}<br>
});<br>
<br>
I hope it might help you!<br>
<br>
Geoffrey<br>
