Examples of TreeStore

com.extjs.gxt.ui.client.store.TreeStore
A store for hierarchical data.
The parent child relationships are handled internally by the store. It is important to note that the store does not use the the parent and children of any TreeModel instances added to the store.
It is important to note the sorting behavior when working with TreeStore. When a sorter is set, it is applied to all existing models in the cache and the Sort event is fired. At this point, the sorter is enabled and active.
Remote sorting is not supported with TreeStore.
Events:
Store.BeforeDataChanged : TreeStoreEvent(store)

Fires before the store's data is changed. Apply applies when a store is bound to a loader.
- store : this
Store.DataChange : TreeStoreEvent(store)

Fires when the data cache has changed, and a widget which is using this Store as a Model cache should refresh its view.
- store : this
Store.Filter : TreeStoreEvent(store)

Fires when filters are applied and removed from the store.
- store : this
Store.Add : TreeStoreEvent(store, parent, child)

Fires when models have been added to the store.
- store : this
- parent : the parent
- children : this list of model(s) added
- index : the insert index
Store.Remove : TreeStoreEvent(store, parent, child)

Fires when a model has been removed from the store.
- store : this
- parent : the parent
- child : the removed child
- children : all the children (deep) of the removed item
Store.Update : TreeStoreEvent(store, model, record)

Fires when a model has been updated via its record.
- store : this
- model : the model that was updated
- record : the record that was updated
- operation : the update operation being performed.
Store.Clear : TreeStoreEvent(store)

Fires when the data cache has been cleared.
- store : this
Store.Sort : TreeStoreEvent(store)

Fires after a sorter is applied to the store.
- store : this
de.odysseus.el.tree.TreeStore
Tree store class. A tree store holds a {@link de.odysseus.el.tree.TreeBuilder} and a{@link de.odysseus.el.tree.TreeCache}, provided at construction time. The get(String) method is then used to serve expression trees. @author Christoph Beck
