[pygtk] progressbar not progressing

[Pascal Duchatelle]

Hi,

I used the progressbar example as a basis to try this widget out.
Basically I have a main window with a pbar and a statusbar.
Like in the example given in the pygtk doc, I created a timer and a
function (F1, called by the timer) to "update" the pbar and sbar. Also I
incorporated a print action in F1 so that I could see that it is
called/launched.
I also have a button with a call_back connected.
Basically this call_back is a loop over a textfile that is split in
say 50 parts (2% increments) and some printing to check the process as
well as slowing it down. This is the process of which I want to follow
the progress.
when I start the main, everything goes well, meaning the F1 function is
called and I can see a recurrent printing included in this function.
Then, when I press the button the loop goes well, but no update of
neither the pbar nor the sbar. And when this loop is finished. the
F1 printing resumes, and of course the pbar is shown at 100% and the
sbar with the appropriate (complete) text. It looks like it there is no
update of the main window including pbar and sbar during the loop.
I tried to "update" the set_fraction of the pbar within the loop. It
does not work either.
What did I miss ? Does the pbar need to be .show()n ? It does not seem
 like it from the example.
By the way where is the gobject.timeout described ? I did not find it
in the pygtk reference. Should I rather look in the gtk doc ?
Thanx for your help.

P.S. may be you need to know that the window and its widgets are built
from a glade file. the pbar as well as the sbar are in a hbox that is
in a vbox that is in the mainwindow.all these widgets are retrieved in
the __init.
