Thanks for the answer!
The steps you describe is what i would do if i had no LayerContainers
that group several layer. And these LayerContainers are created
dynamically out of an xml-file. It looks like this:
<nameofGroup>
<layer1> <PointData / ><layer1 />
<layer2> <PointData / ><layer2 />
<layer3> <PointData / ><layer3 />
</nameOfGroup>
The layers are first added to the OpenLayers.Map object. Then i
iterate throug all groupNames and create LayerContainer that contains
all the three layers. Then after the site is loaded and i want to add
another group pushing a button which creates a single LayerContainer
and appends it to the TreePanel.
I just found out how to add another layer to the container, but now
have a problem:
var someLayer=new OpenLayers....
var myNewLayer= new GeoExt.tree.LayerNode({
layer: someLayer,
leaf: true,
expanded: true,
loader: {
baseAttrs: {
radioGroup: "foo",
uiProvider: "use_radio"
}
}
});
layerTree.getRootNode().findChild( "text","layerContainerName1"
).appendChild(myNewLayer);
The new appended myNewLayer is visible in the TreePanel and inside the
group-folder but it does not have a radiobutton like all the other
layers in the folder..
Anyone know how?
And maybe you have an idea how to do all the above described stuff in
a better way? In short i want:
-add new grouped layer containers to the tree panel (by clicking a button)
-add new layer to a certain layer-group in the tree panel (by clicking
a second button)
I would appecriate your help !
thank you
