Subject: [Users] Upgrading from GeoExt 2 to GeoExt 4
Message-ID: <CAAUdRBTH0wnbnP_o7veJ6TJQxpGM778PFypSOFNK0HgKb4Oa2A@mail.gmail.com>

Hello everyone,

I'm upgrading to the latest version of GeoExt (from 2 to 4) and as I see
there are few classes and functions that don't exist anymore like:

GeoExt.data.LayerTreeModel
GeoExt.tree.Panel
GeoExt.tree.Util
GeoExt.tree.Util.updateLayerVisibilityByNode
GeoExt.data.ScaleStore

Why was it deleted and what can I use instead?

Thanks in advance,
Joud
