Fires before a item is added or inserted. Listeners can cancel the action by calling {@link BaseEvent#setCancelled(boolean)}.
- item : this
- child : the item being added
- index : the index at which the item will be added
BeforeRemove : TreeEvent(item, child)

Fires before a item is removed. Listeners can cancel the action by calling {@link BaseEvent#setCancelled(boolean)}.
- item : this
- child : the item being removed
BeforeExpand : TreeEvent(item)

Fires before a item is expanded. Listeners can cancel the action by calling {@link BaseEvent#setCancelled(boolean)}.
- item : this
BeforeCollapse : TreeEvent(item)

Fires before a item is collapsed. Listeners can cancel the action by calling {@link BaseEvent#setCancelled(boolean)}.
- item : this
Add : TreeEvent(item, child, index)

Fires after a item has been added or inserted.
- item : this
- child : the item that was added
- index : the index at which the item will be added
Remove : TreeEvent(tree, item, child)

Fires after a item has been removed.
- tree : this
- item : item
- child : the item being removed
BeforeSelect : TreeEvent(tree, item)

Fires before a item is selected. Listeners can cancel the action by calling {@link BaseEvent#setCancelled(boolean)}.
- tree : this
- item : the selected item
SelectionChange : TreeEvent(tree, selected)

Fires after the tree selection changes.
- tree : this
- selected : the selected items
Expand : TreeEvent(tree, item)

Fires after a item has been expanded.
- item : this
Collapse : TreeEvent(tree, item)

Fires after a item is collapsed.
- item : this
CheckChange : TreeEvent(tree, item)

Fires after a check state change.
