AW.UI.Tree Multiselect


Is it possible to get the Tree to support multi-select?

The code I am trying does not work.
<script type='text/javascript'>
var tree = {
0: [1, 2, 3, 4],
1: [5, 6],
2: [7],
3: [8],
4: [9]
var itemText = ["", "Node 1", "Node 2", "Node 3", "Node 4", "Node 5", "Node 6", "Node 7", "Node 8", "Node 9"];

var obj = new AW.UI.Tree;
obj.setViewCount(function(i){return tree[i] ? tree[i].length : 0});
obj.setViewIndices(function(i){return tree[i]});
obj.setSize(300, 400);

// Add images to indexed nodes.
obj.setItemImage(["", "home", "favorites", "fontsize", "search", "search"]);

obj.setSelectionMode("multi"); // should work

Thanks Alex,

That sort of works.
Every click now either selects or unselects (if already selected).
Unselecting leaves it grey until the next selection.

Is there any way to make the Tree select like the GRID using the Shift key and the Control key for multiple selections?
Single click should select only one node.

I also require that the tree supports virtual mode.
When I have about 2000 child nodes, the expansion is very slow.

Can you suggest how we can speed this up if the Tree doesn't support virtualMode?

The tree and list controls do not support virtual scrolling. I am planning to add this in the future, but currently it is not possible.
