Hi,
Hmm, this is a bit of a mind bender. I'm probably misunderstanding
something here. . .
You have a actor uses EditorPaneFactory that has a ChangeOption
button. If you double click on the actor and press the ChangeOption
button in the "Edit Parameters" window, it adds choices to the entry
in the Editor Pane.
Then, when you hit Cancel, what do you expect to have happen?
I don't think the Cancel mechanism will handle removing the new
choices that were added. You would need to include this logic in your
Pane.
For me, hitting Cancel seems to revert the value I typed in or
select from the list.
Have a look at
ptolemy/actor/gui/EditParametersDialog.java and see how that works.
I suspect that you will need to create MoMLChangeRequests to
properly get this to work. Note further that EditParametersDialog
is a model dialog:
<p> The dialog is modal, so that (in lieu of a proper undo mechanism)
the Cancel button can properly undo any modifications that are made.
This means that the statement that creates the dialog will not return
until the user dismisses the dialog. The method buttonPressed() can
then be called to find out whether the user clicked the Commit button
or the Cancel button (or any other button specified in the
constructor). Then you can access the component to determine what
values were set by the user.
Anyway, forgive me if I'm missing something here.

Hi.
I've been messing with custom EditorPanes and have come up with this
really simple Actor to demonstrate what I'm up to.
The Actor has a single StringParameter. The editor pane displays this
value and an additional JButton. When the button is pressed two more
choices are added to the StringParameter. The ChangeListener isn't
being used yet in the ConfigTestEditorPane class.
For some reason, the Cancel button is no longer working. I suspect the
generated undo change is not being executed in the correct context. Any
ideas how I can correct this?
Thanks
