Hi,
Despite of my advances studying Glamorous Toolkit and making some
advances on "apps" and interfaces, I really don't understand well the
concept of ports and auto-update of values. So I started with a small
excercise from the transcript example as proposed in the GT blog[1]. Its
working as expected, so try to extend the example with a code that shows
my incomplete understanding at [2]. My idea was to create a two panels
browser showing an array. Left panel show a list, and right one was a
text with the selected value of the list. When the values at the right
were updated the list at the left was updated also. Because this was not
working I create a Transcript trying to show if changes on the right
where captured. I have seen the three inter-dependant panes example,
but still I don't get it right. So my questions are:
[1] http://ws.stfx.eu/L277ESMZYIF3
[2] http://ws.stfx.eu/1FOA0OWJ8PWA
a) How can I send the changes in values from the right panel to the one
of the left?
Thanks,
Offray

Hi,
The first problem I see is that you look for the change of port in the
browser, not in the text presentation.
Try by adding onChangeOfPort: inside the text presentation creation block.
Here is a full snippet for that:

Why do you need that? You typically need something from that list and if
you need that you pass it along in the transmission.
Any transmission can have multiple from: clauses specified and in doing so
you get the values of those ports in the block.

If you only want to update the selection, what you need to do is to:
- populate a port in the right pane with the value you want to set as
selection, and
- create a transmission that links that port with the selection port of the
left pane.
Here is a working example:
http://ws.stfx.eu/K6QW6B8FKGAK
To play with it:
- select a
- then press the play button on the right pane
==> b gets selected in the first pane.

Hi again,
On [1] I have my new experiment:
[1] http://ws.stfx.eu/FC5EQX66TWMA
This shows the current index and the changes on the text port in the
Transcript, but when the uncomment the line
"data at: (data indexOf: value) put: textPresentation text asString"
I get a message "SubscriptOutOfBounds after typing the first change on
the selected element. This is understandable because, as the error
window shows, now I have and updated array, but the value that I'm
looking for is not updated.
There is any way to update the value?
Thanks,
Offray
Ps: By the way, sharing code and questions on it using stfx.eu is really
good for me. I know the code is published for future reference and
uploadable with ZnWorkspace. Just some suggestions:
- To have numbered code lines, to refer and specific line of a published
code.
- Would be nice to open the code in a playground instead of a classic
workspace. They're more interactive and newbie friendly.
- Can the code be published optionally with the author? I imagine
searching for the code I have posted on stfx for solving some future
questions.

Thanks Doru,
Surely this is something I will use in my Grafoscopio project and if
fact was a question I was to ask. If fact, what if I want to go to the
next value of the list, not just from a or c to b, but from a to b and
from b to c? How the code must be changed?
Looking at your code my question about ports is clearer. When you say:
andShow: [:v |
v text
populate: #myWantedSelection
icon: GLMUIThemeExtraIcons glamorousPlay
entitled: 'Update my wanted selection'
with: [ #b ] ].
v is what kind of object? and "populate:" is defining a new port?
In this part:
browser transmit from: #right port: #myWantedSelection; to: #left port:
#selection.
what is a port? a piece of interface? for example the selection?
My current question is more about changing the value on the right panel
and getting it auto-updated in the left one. In another post of this
thread I have updated my advances and questions.
Thanks,
Offray

If you want to find answers to questions like this, simply put a halt in
the code :)
"v" is something you named. I just edited your code. "v" will be an
instance of GLMCompositePresentation.
In this part:
browser transmit from: #right port: #myWantedSelection; to: #left port:
#selection.
what is a port? a piece of interface? for example the selection?

Hi,
My idea came with the auto-update feature of the Transcript.
Imagine I have this two panes browser. Left show a list with values, non
editable. Right shows the selected value on the right as text and the
user can write on it. Suppose I selected the 'a' value on the left list
and start to write on the right panel changing, the 'a' value for 'this
is a test' and get the selected value changed in real time via
auto-update on the left panel, without any explicit button or event
except for the writing itself.
It's a way to circumvent the fact that list/trees are not editable
directly and use panels, ports, transmissions and auto-update to get
changes reflected in real time.
Still don't know if I'm explaining myself better (its kind of a deja-vu
as a newbie in this community) but let me know how can I made this user
example better.
