Hi Alessandro,
Thanks for your feedback. I wrote down your comments and should look
at them in the following days.
Thanks again,
Alexandre

There you go :

Only added nodes are currently managed. I still need to do some work
for the removed nodes.
Hi,
thanks for sharing this useful component!!
I'm also working on a similar tree, I tested yours but since I use a
lot of GeoExt "magic" (a layer store and no explicit calls to map),
the tree is not automatically populated because the layerStore add
event takes place before the tree itself exists.
I had to add a listener to the tree, I'm not sure it is the preferred
method, but maybe you want to add it to the code:
// ABP: make sure tree is populated
onAfterRender : function(self){
// ABP: what if the store was already populated but the tree
is empty?
if(! this.root.childNodes.length && this.layerStore.getRange() ){
this.onLayerAdded(this.layerStore,
this.layerStore.getRange(), 0);
}
},
... and in initComponent
// ABP: add event handler
this.on('afterrender', this.onAfterRender);
Another issue is with the checkboxes, it seems like unchecking a
children, unchecks the whole tree (upwards) even if a sibling is still
checked.
The best option would be to have a tristate checkbox for partially
checked subtrees.
