[Users] Legend tree custom image URL

[Christian Mayer]

Hi Hugo,

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

Cheers,
Chris

Betreff: Re: [Users] Legend tree custom image URL

Hi guys,

I've made a small change to the WmsLegend class and now it works perfectly.
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,

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,
