Partial Layouting

Hello Stoyan,

Well it would seem i am bugging too much, but as i am exploring the component, i am coming across things which would be direct requirements for us.

Please let me know if partial layouting is possible?
By partial layouting i mean, i would select only some of the shapes and connections and say "Grid Layout selection", and it layouts only selected shapes and connections.

In complex diagrams (600 boxes and 1566 arrows) where layouting takes a lot of time be it grid, anneal or spring, this feature (if available) could be a time saver.

Also i was wondering if incremental layouting is possible?

Thanks a lot for your superfast replies. I like the support offered.

Cheers

Phil

Hello Phil,

There isn't any straightforward method for partial layouting available. I guess that could be implemented by setting IgnoreLayout = true for all boxes not in the selection, and limiting the layout area.

The layout area can be explicitly limited only in the anneal layout through the LayoutRectangle property. For the other layouts you might have to temporarily change the DocExtents value. We can easily add a LayoutRectangle property to the spring layout too, but I'm not sure about the grid layout.

Hello Stoyan,

Well that would be great if we have a layout rectangle in Spring/Grid layouts. Will these be a part of V5.0??

Let me know if any other partial layouting technique would be there. Ignore layout is not what i want, as i would need all boxes in an island of diagram to be layout.

You see, would be having islands of connected boxes, and i will choose to appply layout to only one of the island.

Please let me know. Thanks in advance.

Cheers

Phil

Hello Phil,

In a couple of weeks we'll release a 4.2.2 version with several small new features, and will add LayoutRectangle there.

We can add an overloaded Arrange method that takes a collection of nodes to be laid out. That will be available only in the layout classes that are based on physical simulations.

Hello Stoyan,

Thanks ... that would be great. Will wait for that version.

Please do not forget the UseLongestPath property of the Grid Layout and the PDF export text formatting issues. With all these fixed, it would be great. however personally i would be looking forward to V 5.0

Cheers

Phil
