Hi Kevin, I don't think Vergil supports creating custom configuration panes. It probably should, but it does not.
If I understand you correctly, then it looks like you are creating an actor and then when you click on the actor, you would be able to edit some parameters in the parent container. The way I would do this is to have the actor have parameters that are set to composite actor (aka toplevel) parameters in the container. Usually, one would then right click on the background of the composite actor to edit the parameters. You could try using ptolemy.moml.SharedParameter: "This parameter is shared throughout a model. Changing the expression of any one instance of the parameter will result in all instances that are shared being changed to the same expression. An instance elsewhere in the model (within the same top level) is shared if it has the same name and its container is of the class specified in the constructor (or of the container class, if no class is specified in the constructor)." Some of the early Ptolemy models don't use vergil and instead have their own UI. See the CSP Dining Philosophers example and the CSP Bus Contention example. You could do something similar, but that would mean you would not be using Vergil. _Christopher Christopher Brooks (cxh at eecs berkeley edu) University of California Programmer/Analyst Chess/Ptolemy/Trust US Mail: 558 Cory Hall #1770 ph: 510.643.9841 fax:510.642.2739 Berkeley, CA 94720-1770 home: (F-Tu) 707.665.0131 (W-F) 510.655.5480 (office: 400A Cory) -------- Hi all, I'm a Ptolemy rookie so please point me to FAQ or other documentation if available. I have written a TypedAtomicActor which has a few StringParameters to control its behavour. Also, I've written an EditorPaneFactory for this actor which presents some custom configuration panes. The factory returns an object which derives from JPanel and uses code roughly like this : public HelloWorldEditorPane( NamedObj container ) { super(); parent = (HelloWorld) container; PtolemyQuery hostQuery = new PtolemyQuery( container ); hostQuery.setTextWidth( 40 ); hostQuery.addStyledEntry( parent.url ); hostQuery.addStyledEntry( parent.user ); hostQuery.addStyledEntry( parent.pass ); this.add( hostQuery ); } This code using the PtolemyQuery has been cribbed from the ptolemy.actor.gui.EditorPaneFactory.createEditorPane() method. The problem that I see, is the addStyledEntry() method (through the PtolemyQuery.attachParameter() method ) ends up adding this to the ValueListener list of the StringParameters such as parent.url. Since this list is implemented as a standard LinkedList, the StringParameter hold on tightly to the PtolemyQuery object and that object is never freed. In order to remove this from the value listeners, I'd have to call parent.url.removeValueListener( hostQuery ) when the hostQuery object is no longer needed (such as when the configure window is closed). But I don't think the Panel that I created ever receives notification that the configure dialog has been closed. Is there some way to work around this issue? Is there some actor in there which does this properly. Thanks for the advice.
