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, ie., 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
