What is the best way to make a thick arrow connector? [message #191041]

Dear All,

I am looking at doing a visual modelling tool for HL7. We use a
graphical notation where the connectors are (colour coded) thick arrows
containing text showing some of the attributes e.g. (in Ascii art)

--------------------------------\
| Attribute A \
| Attribute B /
--------------------------------/

A) How is this best achieved in GEF/Draw2D?
B) Is there anywhere a collection of "user contributed" stencils/shapes
such as the above so people don't have to re-invent the wheel on shapes etc?

TIA

Adam

PolylineConnection supports children and places them using a Locator as the
constraint. There are no included figures currently for doing what you want
to do. You could use some kind of label and border combination perhaps, but
you might need some new locator type. You're in new territory I think.

Oh t'riffic. My favourite place is to be out in front of the herd <G>....

BTW has anyone given any thought (esp in the context of the GMF etc
project helping to grow eclipse/emf/gmf as modelling tool foundations)
towards a kinda "stencils/shapes contrib" section? i.e. If/When I create
myself my thick colourable arrow as below I'd like to think others could
simply reuse it, but where would I send/put it?

If it is a general purpose figure it belongs in draw2d. Feel free to
contribute code when you have something working.

Adam, if you can spare thick-lines without labels...then changing
PolylineConnection's lineWidth with setLineWidth and changing
foregroundcolor should suffice. Though this seems silly I thought of
mentioning it.

Thanks
Venkat
