Add hover node gesture #13

Closed ogallagher closed 2 years ago

ogallagher commented 2 years ago

Branch: nodegesture-hover

In addition to having the drag translation node gesture (and drag handle resize cell gesture), a hover node gesture could be used to make graph nodes (cells or messages) hoverable.

One application for such a gesture would be sequence diagram message edge details, as suggested at sirolf2009/fxgraph #10.

Another would be for Cartesian plot points, which could show x,y coordinates on hover.

During development I’ve realized that MessageEdge spans the entire area from 0,0 to its end point, adding an extra challenge for trying to make sequence diagram messages hoverable:

Hover node gestures now have basic implementation. See below for a demo using SequenceDiagram.ActorCell as hoverable graphics:
