Re: [kepler-users] Port parameter like "combo box" - do we have something like this in Kepler

Wed, 24 Sep 2014 13:00:41 -0700 

Hello Christopher,


I may be confused here, but doesn't ChoiceStyle do this?

http://ptolemy.eecs.berkeley.edu/ptolemyII/ptII8.0/ptII/doc/codeDoc/ptolemy/actor/gui/style/ChoiceStyle.html

(BTW - About dynamic comboboxes, see:
https://lists.eecs.berkeley.edu/sympa/arc/ptolemy-hackers/2008-07/msg00010.html)
This is something I am looking for, I will investigate it further! Thanks for sharing this one. 



$PTII/bin/vergil
http://ptolemy.eecs.berkeley.edu/ptolemyII/ptII8.0/ptII/doc/codeDoc/ptolemy/actor/gui/style/ChoiceStyle.html
uses it in the AudioCapture actor:
When it comes to your sample file. In your png file, take a look at "orred" parameter on the right to SDF director. This is exactly the place I want to have values {7, 8, 9 } instead of just 7.
And I want to make sure that user will be able to choose from predefined list instead of being forced to type the value. 

Cheers

Michal






SoundSpectrum.xml contains:

<entity name="AudioCapture" class="ptolemy.actor.lib.javasound.AudioCapture">
        <property name="sampleRate"
class="ptolemy.actor.parameters.SharedParameter" value="8000">
            <property name="style" class="ptolemy.actor.gui.style.ChoiceStyle">
                <property name="8000"
class="ptolemy.kernel.util.StringAttribute" value="8000">
                </property>
                <property name="11025"
class="ptolemy.kernel.util.StringAttribute" value="11025">
                </property>
                <property name="22050"
class="ptolemy.kernel.util.StringAttribute" value="22050">
                </property>
                <property name="44100"
class="ptolemy.kernel.util.StringAttribute" value="44100">
                </property>
                <property name="48000"
class="ptolemy.kernel.util.StringAttribute" value="48000">
                </property>
            </property>
        </property>

The way this appears in the model is that
$PTII/ptolemy/actor/lib/javasound/javasound.xml has similar code so that in
Vergil, when the actor is dragged in, the choices appear.

I'm not sure how this would work in Kepler.

Hi Michal,
For use at runtime, you can present a combobox dialog that prompts for a 
selection and then outputs the selected value. Take a look at the Python 
examples distributed with Kepler to see if this will be useful for you.

Hello Kepler team,

I am looking for something that resembles combo box inside workflow.

The idea here is that I define the parameter with values: {"a", "b", "c" } and 
then, I choose from one of these by right-click or click.

Question here is. Do we have something like this in Kepler.

Our approach, now, follows:

a = "some value"
b = "some value b"
c = "some completely different value"
actual_parameter = a|b|c

This way, we can determine the value of the parameter while still making 
everything pretty much consistent.

However, this requires to edit the value and requires numerous parameters on 
canvas. If you have few of them with lots of options they can consume most of 
the workflow canvas.

So, question is: do we have some sort of combo box as parameter inside Kepler.

Thanks for the info

Michal
