Patrick,
There is an example in the ptII development tree that uses Python for
GUI work.
Bob Weber sent me a model that I folded in as
$PTII/ptolemy/actor/lib/python/demo/RecordManipulation.xml
I've attached the model.
The Ptolemy II development tree also includes a draft system for laying
out components
in a runtime window. In the Ptolemy II development window, View ->
Interface Window brings
up a run control panel that is editable.
We stopped work on this when we submitted changes to the underlying
package and the author
said he was moving to Eclipse RCP.
To access the Ptolemy II development tree, see
http://chess.eecs.berkeley.edu/ptexternal
For information about Kepler and Python, see
https://kepler-project.org/developers/reference/python-and-kepler
There is also a thread at
http://lists.nceas.ucsb.edu/kepler/pipermail/kepler-users/2011-November/002044.html
about Kepler and Python.

As I said before:
They aren't as limited as you think...
If a parameter contains an attribute that subclasses
ParameterEditorStyle, then that attribute controls
how the interaction with the parameter is done.
See the
$PTII/ptolemy/actor/gui/style directory.
In addition, you can completely customize the
dialog that Configure Actor opens.
See EditorFactory and its subclasses for examples.
For an example, the PythonScript actor in the library
opens a text editor when you select Configure Actor.

Hi Patrick,
I was thinking the same thing today, and was having a look at
wxPython. However, I am in the early days and so can't help you re:
experience.
At this point in time I am almost tempted to run Kepler from the
command line:
https://kepler-project.org/developers/reference/executing-kepler-from-the-command-line.
The python/java GUI buttons would simply change default object
assignments in the kepler/java script before running the project.
There though should be a better way, as it would not be
computationally smart to have two interpreters stacked on top of each
other.
re: other toolkits. The forthcoming book
http://www.amazon.com/Programming-Graphical-Interfaces-Chapman-Series/dp/1439856826
also enables learning GUIs for R.
I agree with you. The bottom line is that there is a need for custom
interfaces for endusers of the kepler workflow, as soon as the
workflow gets complex. Most of my endusers are familiar with excel
and that is it when it comes to software, and don't want to venture
too far out. For example a technician typing in soil and plant
parameters, before getting a soil water balance from Kepler.
Something like RExcel means they can plug in numbers in a
spreadsheet, and get their outputs. In a workflow this would mean that:
1) Run the workflow in Kepler,
2) An excel styled spreadsheet would pop-up, pre-populated with
default parameters, and perhaps some pre-specified data [e.g. swing
pulldown to source locally held weather station data].
3) End user would type in their numbers, then press 'done'
4) Kepler would continue to execute with the new information.

Subject: [kepler-users] component gui
The GUI creation tools under the 'Configure Actor' (for creating
custom interfaces for setting actor parameters) are limited (for
example, no sliders, no drop down lists, no tabs, no free text, no
layout constraints, etc). In particular, I find this an issue when
defining complex Python actors with lost of different parameters. As
a result, the interface can end up being a bit unfriendly for the end
users of my actors.
I am wondering - what is the best way of overcoming this? Has anyone
had any experience creating custom GUIs for actors using either Java
or Python, for example using Swing or other toolkits?
