Second question, can be TreeVirtual configured to have only one
leaf opened at time?
For example, I have
/root
/a
/b
/c
If I open (expand) /root/a - all others will collapse; /root/b,
/root/c
Is this configurable, or I need to write own listener? :)
That functionality is not available out of the box, but should be easy
to implement with your own listener.
You could add it to "out-of-box", here is implementation.
And, of course I'm understand that inclusion of this code not guaranteed
at all :)
closeAllExceptNode: function(tree, node)
{
if(node.parentNodeId == 0)
return;
var arr = tree.getDataModel().getData();
var parent = arr[node.parentNodeId];
for(var i = 0; i < parent.children.length; i++)
{
if(parent.children[i] != node.nodeId)
{
var child = arr[parent.children[i]];
if(child.bOpened)
{
child.bOpened = false;
}
}
}
this.closeAllExceptNode(tree, parent);
},
