[Users] How to turn on/off a radio button in a layer tree nodeprogrammatically?

[Steve.Toutant at inspq.qc.ca]

Set the layer visibility to false will also uncheck the node. 
Perhaps it depends on how you built your tree...

Hello,
 
To check or uncheck the node ?i? of your tree you can use something 
similar to this :
 
layerTreeRoot.childNodes[i].ui.toggleCheck(false)
or 
layerTreeRoot.childNodes[i].ui.toggleCheck(true)
 
And for the radio button I don?t know but I think it should be something 
similar.
 
Good luck
 
François

Hello everyone:
 
I am learning GeoExt and trying the example "Tree Node", the url of the 
example is "http://api.geoext.org/1.1/examples/tree.html".
 
In the example, the "Overlays" subtree hosted in the Layers panel contains 
3 layer nodes each with a check box and a radio button, users can click on 
one of radio buttons to activate a layer, and through checking on/off 
check boxes, we can turn on/off the display of a layer. These functions 
are excellent.
 
Now the question is, I want to turn on/off a radio button in the treenode 
programmatically, also check on/off check boxs programmatically. Could 
anyone provide me some hints to achieve the goal? Do I need to examine 
some source code of the library?
 
Thanks,
Chamme_______________________________________________
