RE: Graph and GraphElement in Java

[Fred Wan]

Hi

I have trouble understanding the following fragment in SimpleObserverBug and
translating it to Java. Can someone help me out here? Especially the
M(drawSelfOn) is puzzling. In jheatbugs a message is sent to a heatbug
object that then draws itself, but what happens here is unclear.

Thanks,

  bugDisplay = [Object2dDisplay createBegin: self];
  [bugDisplay setDisplayWidget: worldRaster];
  [bugDisplay setDiscrete2dToDisplay: [modelSwarm getWorld]];
  [bugDisplay setObjectCollection: [modelSwarm getBugList]];
  [bugDisplay setDisplayMessage: M(drawSelfOn:)];   // draw method
  bugDisplay = [bugDisplay createEnd];

The `gui' interfaces are available if you really want them, but
you need to rebuild Swarm from source with a few changes.¹

Instead, I would suggest you go to www.jars.com and search for "plot".
`ptplot' is one that I know works.

¹ The variable *removed-protocols* in java-stub.el (or interface.el
in the snapshot sources) is a list of all the protocols that are taken
out of the Swarm/Java layer.  Simply remove the lines you want back and
do a new build/install.
