class GeoExt.tree.BaseLayerContainer

A layer container that will collect all base layers of an OpenLayers map. Only layers that have displayInLayerSwitcher set to true will be included. The childrens’ iconCls defaults to “gx-tree-baselayer-icon” and this node’ text defaults to “Base Layer”.

Children will be rendered with a radio button instead of a checkbox, showing the user that only one base layer can be active at a time.

To use this node type in TreePanel config, set nodeType to “gx_baselayercontainer”.
