Hello GeoExt List,
I am new to GeoExt and so far I am very grateful that such a library is out
there. I have made a map browser and now I want to have a customized layer
panel. I have somewhat a grasp on how to create general layer trees, but
I'd like to be able to customize mine as much as possible. I am not sure if
it's because such options do not exist or if I am just unaware.
Here's a list of what I'd like to do:
1. I'd like to be able to have a few variables for my layers as so:
var tib_townships = new OpenLayers.Layer.WMS(
"Townships (Tibetan trans)", "
http://10.0.102.11:8080/geoserver/wms";, {layers: 'cite:tib_townships',
transparent: true}, {isBaseLayer: false, displayInLayerSwitcher: true,
visibility: true}
);
var chn_villages = new OpenLayers.Layer.WMS(
"Villages (Chinese trans)", "
http://10.0.102.11:8080/geoserver/wms";, {layers: 'cite:chn_villages',
transparent: true}, {isBaseLayer: false, displayInLayerSwitcher: true,
visibility: false}
);
var tib_villages = new OpenLayers.Layer.WMS(
"Villages (Tibetan trans)", "
http://10.0.102.11:8080/geoserver/wms";, {layers: 'cite:tib_villages',
transparent: true}, {isBaseLayer: false, displayInLayerSwitcher: true,
visibility: true}
);
and then create this layernode to house these layers
var layerRoot = new Ext.tree.TreeNode({
text: "All Layers",
expanded: true
});
layerRoot.appendChild(new GeoExt.tree.BaseLayerContainer({
text: "Base Layers",
map: map,
expanded: true
}));
layerRoot.appendChild(new GeoExt.tree.LayerNode({
text: "Tibetan Villages",
layer: tib_villages,
loader: {param: "LAYERS"},
expanded: true
}));
