getAllExpandedKeys ();
The getAllExpandedKeys method returns an array of keys that belong to all expanded tree nodes.
To execute this example, the page must contain the TreeList component named treeListSett (seebsp; an example of the TreeList.NodeUnHovered event). Expand all nodes and set selection for the expanded nodes:
treeList.setMultiSelect(true);
treeList.expandAll();
nodes = treeList.getAllExpandedKeys();
treeList.setSelectedByKeys(nodes);
After executing the example all nodes that have children, are expanded and selected.
