Updates made to WPF graphing application

November 17, 2009

I recently published an article on CodeProject that reviews a WPF graphing application.  It turns out that my original circular dependency detection algorithm did not detect all circles in certain scenarios.  I completely rewrote that algorithm, so that it now properly detects all circles in any object graph.

I also modified the way that the node connectors move, so that it feels more responsive and elastic.  The app is much better now, and the article has been updated to reflect these changes (including a new source code download).  If you want to check it out, here’s the link:

WPF graph that detects circular dependencies

November 16, 2009

I spent the weekend having a blast writing a WPF app that displays an interactive object graph, and detects/highlights circular dependencies. It was so much fun, that I decided to publish an article about it on CodeProject.

Here’s a screenshot of the app:

ComplexCircularGraph

The app uses Charles Petzold’s ArrowLine element, PropertyObserver and ObservableObject from my MVVM Foundation library, DragCanvas from WPF.JoshSmith, and ContentControl3D from Thriple.
