Box overlaps after applying a Layout

Hi,

Is there a way to prevent boxes from overlapping each other after applying one of the layouts?  The Grid and Spring layouts in particular tend to position boxes so close together at times that they overlap, which looks ugly.

All the boxes are flagged as obstacles, but this doesn't stop them colliding.

I suppose I could increase the distance properties of the layouts to force the boxes further apart, but is there another way?

Thanks.

Hi,

The Obstacle property is used only by the arrow routing algorithm.

You can set a GridLayout.GridSize larger than any of your nodes to avoid them overlapping. The SpringLayout runs some physical simulation and we really don't have much control at what position a node would end up.

You could use the NodesIntersect method to find if there are some intersecting nodes, and if there are, move them further one from the other using the MoveTo method.

Ok, thanks.

It would be a useful feature in a future version of your control to prevent box collisions during a layout.
