Hi,

I need to include nodes to layout algorithm (e.g. tree layout) but I need to specify that position of this nodes must not be changed as the result of layout.

Whether there is a way to make it?

Thanks in advance.

I've already tried that. But this is not exactly what I need. I'll try to explain. Please look at the picture:

That's what I need:
Pic 1) It's a default treelayout result
Pic 2) Positions of the nodes after user interaction
Pic 3) After selecting node #2 and pressing some button, node #2 layed out as if all nodes where counted by algorithm but position of other nodes didn't changed.

Here is what I get ( see pic 4).

If I set IgnoreLayout=true for all nodes excepts nodes I need to layout then nodes stayed in their places, but in some cases they can overlap with each other which is not acceptable.

4b shows that user drags node #4 and then pressed some button which run layout function. I need that after layout function nodes positions become like in 4a. But instead of this node #4 overlap node #3 because node #1-#3 excluded from layout by setting IgnoreLayout=true.

My goal is to include all required nodes to the layout algorithm so they take part in algorithm computations, but only selected by user node changes their positions.

That's what I afraid of I'll try that, thank you for your help!
