Hi Hugo, isn’t it the UrlLegend class [1] what you need?

I've just added the following code inside the getLegendUrl method (at line 145): if (rec.get('legendURL') != ''){ url = rec.get('legendURL'); } Obviously this assumes that if legendURL is different than an empty strig, it will override the url returned by the styles definition. Cheers, 2014-10-28 19:13 GMT+00:00 Hugo <hfpmart...@gmail.com<mailto:hfpmart...@gmail.com>>: Hi all, I'm building a tree panel similar to the example LegendTree. So far so good, I'm able to use gx_wmslegend ctype to show the legend below each node in the tree. However there is a case where i need to override the legendURL and point it to a specific image instead of using the default GetLegendGraphic. I have sucessfully implemented this override in a GeoExt.panel.Legend by "manually" seting the layer record legendurl field [eg: layerRec.set("legendURL", rec.data.legURL);] When trying the same approach on th gx_wmslegend it doesn't work. I was reading through the docs of this xtype and it states that the image can be read from the styles field of a layer record When looking at the layerModel i cannot see this field defined. So my question would be, where should i set this styles field? GeoExt layer record? Openlayers layer record? How would it look like? Thanks in advance. Cheers, -- Hugo Martins -- Hugo Martins
