[pygtk] Restore a scrolling position

[Lionel Dricot]

Hello,

In a previous mail, I asked about restoring the scrolling position in a
treeview :
http://www.mail-archive.com/pygtk@daa.com.au/msg17224.html

This was solved thanks to Neil and Walter with the following line of codes
at the end of my refresh function :
gobject.idle_add(self.task_tview.get_vadjustment().set_value,vscroll_value)
gobject.idle_add(self.task_tview.get_hadjustment().set_value,hscroll_value)

(with values being read at the start of the refresh function, of course)


But I discovered a problem : if elements have been removed from the
treeview, the scroll will go to an empty position.

In some case, it means that you will see only a blank treeview because
remaining elements are hidden on top (but no scrollbar are displayed).

So how can check before inserting the scroll_value that I didn't pass the
upper bound of the possible scroll ?


Thanks in advance for your help,

Lionel
