Re: Simple Tree-Layout

[Benjamin Aaron Degenhart <b.degenhart.study AT gmail.com>]

I see, thanks for your reply Yoann!

Then I am wondering though why the layout produced by the HierarchicalLayout class looks so odd in comparison to the result by an equivalently named algorithm in yEd for instance: https://gist.github.com/benjaminaaron/91c5b737c86b9abc7301

Guilhelm, am I using your class wrong?

Best regards,

Benjamin

Hi Benjamin,

Your code is actually running two layout algorithms; the default one and the hierarchical one.

In order to deactivate the default layout, pass parameter `false` to the graph.display method :

Viewer viewer = graph.display(false);

Since the hierarchical layout computes only once (after each graph update  I guess), this will also answer your second question about animation.


Regards,

Yoann
