Hi!
Does anyone know how to programmatically rearrange the port order in
an actor in Ptolemy II? In an actor, the ports appear in creation
order. Is there a way to rearrange them and still keep any existing
connections intact? Please provide sample code.
Thanks.

We have experimented with techniques for rearranging ports, but haven't
yet found a satisfactory mechanism, except for a mechanism that permits
changing whether they are placed on the top, bottom, right, or left.
The problems we ran into with rearranging ports were mostly UI
issues:
* It was hard to know when to propagate the changes to the model
* It was hard to control the exact site on the actors where the ports
were to be connected.
The next release of Ptolemy II will include the top, bottom, right or
left mechanism. (Our tentative plans include a runtime only release of
the CT domain and vergil at the end of the month and a full source
release of Ptolemy II in May.)
The changes were somewhat complex and not that amenable to a patch.
The affected files were:
* actor/gui/PortLocationConfigurer.java
* actor/gui/PortLocationDialog.java
* vergil/kernel/SetIconAction.java
* vergil/kernel/PortLocationDialogFactory.java
New Files that implement the icon editor (set icon and place ports)
* ptolemy/vergil/actor/ActorController.java
* ptolemy/vergil/ptolemy/kernel/EntityPortController.java
* ptolemy/vergil/toolbox/PortSite
Changes for set icon and place ports
There might have been other changes as well. Generating a patch
for these would take quite a bit of effort, so at this point I'm going
to decline that task.
