Is it possible to get a list of the nodes in a diagram in order of their position in the Z-Order?

Is it possible to get a list of the nodes in a diagram in order of their position in the Z-Order?

Accessing the diagram's child nodes through the model layers will let you get hold of the nodes according to their Z-order. Populating the 'nodesInZOrder' list in the manner shown below will set it up with the diagram's child nodes in order of increasing Z-order, i.e., the bottom-most node will be the first item in the list while the topmost node will be the last.

C#

ArrayList nodesInZOrder = new ArrayList();
foreach (Layer layer in this.diagramComponent.Model.Layers)
{
    IEnumerator inodes = layer.GetEnumerator();
    while (inodes.MoveNext())
    {
        nodesInZOrder.Add(inodes.Current);
    }
}

VB

Dim nodesInZOrder As ArrayList = New ArrayList()
Dim layer As Layer
For Each layer In Me.diagramComponent.Model.Layers
    Dim inodes As IEnumerator = layer.GetEnumerator()
    While inodes.MoveNext()
        nodesInZOrder.Add(inodes.Current)
    End While
Next
