In my use case, I will likely need to override BaseTouchBehavior to create a customized touch behavior implementation. This may also result in needing to create a customized TouchController as well.

I was just curious if there are any examples for overriding either of these two classes that may be helpful to learn from? Even if the examples come from the WPF, Android, or other some other version of the Diagramming library?

Just to give you an idea of the kind of behavior I am looking to implement: it is very similar to the "Pan and Modify" behavior, except for one additional point - I want to let users draw links by doing the following steps:

1. Pressing/tapping/clicking on an AnchorPoint begins drawing a new link from that point.
2. Pressing/tapping/clicking on another AnchorPoint completes the new link, terminating it at that point.
3. As an alternative to number 2 above: If the user holds the finger down and drags, the link is drawn as the user drags his finger.

Some of these behaviors are similar to the "DrawLinks" behavior, but not identical.

Anyway: I'm just curious if there are examples to learn from regarding overriding the classes I mentioned above (BaseTouchBehavior and TouchController). Thanks!

Thank you for that example! It was very helpful to see how to interact with the API to accomplish that goal.
