[pygtk] CList (continued)

[Jamey Cribbs]

Thanks for all the responses on my CList question.  I thought I would 
respond to all of your questions/advice in one email rather than reply 
to a bunch of different emails.

Here's a update with where I am currently:

Using the TreeModelSort and Liststore, I have been able to get the speed 
of sorting and refreshing (i.e. clearing out the Liststore, grabbing all 
data from database, adding records back in to empty liststore, 
reapplying current sort criteria) pretty close to what the CList was 
doing (at least on a small dataset, approx. 600 records; haven't tried 
anything bigger yet).

I think I have almost everything working the way I want, except for one 
thing.  When I do a refresh (see above for definition), in my refresh 
method, after I clear out the liststore and then add back the records, I 
call set_cursor on the treeview to make the treeview jump to the record 
that was selected before the user clicked the "Refresh" button.  This 
works fine.

What doesn't work is similar functionality for when the user clicks on a 
column header to change the sort.  For example, let's say the treeview 
is currently sorted on the first column in ascending order, a row has 
been selected (i.e. it has the blue background) and it is visible inside 
the scrollview.  Now, I click on the second column header to sort the 
treeview on that column.  The treeview sorts on the second column just 
fine.  The same row stays selected, BUT the treeview does not scroll to 
make that selected row visible.  That's my problem.

I have tried doing:

self.treemodelsort .connect_after('sort-column-changed', 
self.afterSortColChanged)

and in the afterSortColChanged method I do a

self.treeview.set_cursor(self.tms.convert_child_path_to_path(self.store.get_path(focusRowIter)))

where focusRowIter is the iter of the lisstore that was the selected row 
before the sort was done.  But it doesn't help.  Why does it work after 
I clear out all the records and re-add them, but doesn't work after the 
treeview is sorted?  What am I doing wrong?

I feel like I am getting pretty close to duplicating the functionality 
that I used with the CList.  Thanks again for all of the help.
