Re: Webstart example reimplementation using graph v2?

Hi Peter,

The VMD style is defined to be used by GraphPinScene where edges are
defined as a connection between two pins. Pins are attached to
particular nodes.

The anchor shapes are actually painted as a part of VMDConnectionWidget,
so they appear automatically only when a connection is shown. For the
code, see:
graph/lib/src/org/netbeans/api/visual/vmd/VMDConnectionWidget.java
file and POINT_SHAPE_IMAGE static field which is used by calling
"ConnectionWidget.setEndPointShape(POINT_SHAPE_IMAGE)" method.

If you want to show them always then you would have to create your own
VMDPinWidget or VMDNodeWidget which will contain even an ImageWidget
which uses
"graph/lib/src/org/netbeans/modules/visual/resources/vmd-pin.png" image.

A problem of the library is that it contains only one pre-defined style
(the VMD style) which has limited usage. Therefore if you have an
idea/implementation of another style I would be happy to integrate it
into the library.

Regards,
  David
