I was searching for a while now and hope you have a few good tipps for me for starting the following:
I want to write a plugin that will allow Rational Software Modeler (RSM) which is based on GMF to support highlighting of relevant parts of an Activity Diagram. We have pretty comprehensive diagrams and sometimes can't see what is connected to what.
I want to be able to select a node and have all connected edges and maybe connected nodes highlighted. I ask my self the following questions:
* Can I modify how a node is displayed in a diagram to highlight it without changing the view model, so that I do not persist the highlight, when I save the model? (maybe I can only modify how it is rendered)
* Can I register myself to some "mouseover"-event for the nodes in a diagram?
Or maybe someone has done something similar already.
Any help is kindly appreciated.
Thanks in advance,
