Class Detail

GeoExt.tree.LayerNode()

A subclass of 'Ext.tree.TreeNode' that is connected to an 'OpenLayers.Layer' by setting the node's layer property. Checking or unchecking the checkbox of this node will directly affect the layer and vice versa. The default iconCls for this node's icon is "gx-tree-layer-icon", unless it has children. Setting the node's layer property to a layer name instead of an object will also work. As soon as a layer is found, it will be stored as layer property in the attributes hash. The node's text property defaults to the layer name. If the node has a checkedGroup attribute configured, it will be rendered with a radio button instead of the checkbox. The value of the checkedGroup attribute is a string, identifying the options group for the node. To use this node type in a ``TreePanel`` config, set ``nodeType`` to "gx_layer".

Field Detail

{boolean} autoDisable

Should this node automattically disable itself when the layer is out of range and enable itself when the layer is in range. Defaults to true, unless ``layer`` has ``isBaseLayer``==true or ``alwaysInRange``==true.

{OpenLayers.Layer/String} layer

The layer that this layer node will be bound to, or the name of the layer (has to match the layer's name property). If a layer name is provided, ``layerStore`` also has to be provided.

{GeoExt.data.LayerStore/String} layerStore

The layer store containing the layer that this node represents. If set to "auto", the node will query the ComponentManager for a :class:`GeoExt.MapPanel`, take the first one it finds and take its layer store. This property is only required if ``layer`` is provided as a string.
