While testing and studying the Network Model in Mason Tutorial 5, I
find that although the "SimplePortrayal2D" class could be extended to draw
the Network Nodes in a "ContinuousPortrayal2D" Field, the Nodes seem not
to be movable by mouse drag when the model is being paused.
Is there a way to modify Tutorial 5 so that, when the model is being
paused, I could drag a Node to move it around while the Node's edges would
redraw themselves to reflect the Node's updated location ?
Thanks for any suggestion.
