Yeah, it's a bit more complicated than simply reassigning the parent; it
also needs to be removed from the old parent's child list and added to the
new parent's child list. I just committed a change to SimpleTreeDataModel
that adds a move() method. Give current trunk a try. Here's a snippet from
my test program:
var tree = new qx.ui.treevirtual.TreeVirtual(["Tree"]);
container.add(tree, { flex : 1 } );
var dm = tree.getDataModel();
var root = dm.addBranch(null, "Node One", true);
var sub1 = dm.addBranch(root, "Sub One", true);
var sub2 = dm.addBranch(root, "Sub Two", true);
var child = dm.addLeaf(sub2, "Child");
dm.setData();
var moveTo = sub1;
var button = new qx.ui.form.Button("Move it!");
button.addListener("execute",
function(e)
{
dm.move(child, moveTo);
dm.setData();
moveTo = (moveTo == sub1 ? sub2 : sub1);
});
container.add(button);
