I write a pseudo-code that can hel you and the others to identify my

<pseudo-code>

text to welcome the user

button_up
button_down

I mark page_one of assistant as complete

here I wanto to collect the data from treeview in the order the

def step_finale(self):
confirm all the user parameters

(1) In this point I can't be able to collect the information of the
treeview, so I can't operate on them.
If I understand correctly, your problem is that you think that "step_n"
runs during the time that the user sees the nth page of the assistant.
That's not the way in which the Assistant generally works: you just fill
pages in advance, and then you let the user move along them.
If you have to call "set_page_complete" based on the content/status of
some treeview, probably (depending on what you really need) the best
thing is to just connect to the "changed" signal of the TreeSelection,
and in the callback for that signal check if everything is fine and in
case call "set_page_complete( that_page, True )". You can connect also
to the "changed" signal of more than one widget.
Alternatively, you can monitor the Assistant with some callback called
by glib.timeout_add(), but I think that's generally more difficult to
manage smartly.
If I put a "print" in every step_*() functions to simply debug my app,
on screen I see all the text printed at the beginning of the app.
Yes, that's normal: you first prepare all the pages, then run the
Assistant; its methods do not block the flow of code.
Yes, you undestood correcty what I want to do.
I have already tried to connect a signal from a button (user click when
the treeview
is sorted) to call "set_page_complete(page, True)", but, as you said
previously, this don't
block the flow of code, so I can't collect the data in the next page.
Hope I described good what I want.
Maybe I can't fully understood the Assistant Widget and I'm using it bad.
I mean that until a page in an Assistant isn't marked as "completed",
the user-iteration is in a "waiting-mode"
I googled to search how to use an Assistant, but the tutorials I found
are few and not fully explained.
I hope I've clarified a bit. I guess you already seen
http://www.learnpygtk.org/pygtktutorial/assistant.html ?
bye
Pietro
Yes, I've already saw this page and I started from there.
You have clarified more than a bit and I thank you.
Now I want to try another way I found in this list, this post
(http://www.mail-archive.com/[email protected]/msg19549.html).
In step_two() I can call "get_children" from the assistant to retrieve
the previous page (step_one)
and from this page I call "get_data" from the treeview.
I will try this ...
Thanks, Mauro

Hi,
I have a problem with the creation of an Assistant.
Ehm... which problem?
Pietro
I want to collect information from the user.
In the first page I have a treeview with 3 button (move_up, move_down
and apply).
Until the user don't click on Apply Button, the navigation on the
Assistant is unsensitive.
When the user finished to sort the treeview with the up and down button
and click Apply button, the Next button on Assistant became sensitive
and the user can click it to procede to the second page.
In the second page I want to collect the data from the treeview to make
further processing.
If I have to post some code, tell me, and I will try to post code that
can be executed.
But keep in mind this Assistant is a piece of a bigger project I'm
working on.
Thanks in advance, Mauro
