[Zest] Maintaining order of leaves in SpaceTreeLayout [message #1005293]

Is it possible to maintain the order of nodes in a SpaceTreeLayout? Currently, it seems like every time I refresh the graph, a new ordering of leaves occur. For example, if I have:

1
/ \
2 3

Then add node 4 as a child of 3, I will get:

1
/ \
3 2
|
4

Is there any way to prevent this and ensure the same ordering every time?

Thanks!

Hi,

have you tried adding a comparator using GraphViewer#setComparer or GraphViewer#setComparator. Most layout algorithms respect the order they get their nodes in.

Cheers,
Zoltán
