DirectedGraph - tuning the vertical vs horizontal [message #215406] Tue, 02 May 2006 14:53 Go to next message

I'm using auto layout based on DirectedGraph. It works well, but lays out
my objects more vertically than horizontally. What should I be looking at
to add more horizontal weighting? Thanks

There's an API -->

DirectGraph.setDirection(int direction) that takes a PositionConstant define
as a parameter.

I'm guessing you'd want to use PositionConstants.WEST;

Hello Steven, Do you mean DirectedGraph.setDirection(int direction) ?

But I can find this API in Draw2d and others .What I only find is that
there is a interface Orientable.setDirection(int direction) and its
implemented class.

Can you tell us more about this DirectGraph.setDirection(int
direction) ?
what the package is this class DirectGraph in ? And if possible,can you
give us a sample ?


Thank you Steven very much!
Best Regards to you!

That method DirectedGraph.setDirection() is not available in the Draw2d 3.1
API. AND, when I browse the API, most things are 'for internal use only'.
So I am not sure what I can do to 'tune' my layout to have more horizontal
than vertical. Seems like a limitation, unless I am missing something.

It is new API. For 3.1, you will have to:

1) transpose your input
2) invoke DGL
3) transpose the results
