[pygtk] removing remaining rows in a liststore

[Stuart Hughes]

Hi everyone,

I'm reading data from a file into a gtk.ListStore.  Sometimes the number 
of rows in the file can reduce, so I want to be able to refresh the 
valid rows, and delete the remaining invalid rows so they don't show up.

After refreshing the valid rows (the data runs out), I have an iter that 
points at the first row that I need to remove.  This is what I tried:

while iter:
      self.lstore.remove(iter)

But this just got stuck in a tight loop as iter does not seem to 
increment to the next row (possibly the pygtk2reference I have is old or 
wrong).

So I tried:

while iter:
      iter = self.lstore.remove(iter)

But remove seems just to return True, so I get an exception.

So I tried:

while iter:
     self.lstore.remove(iter)
     iter = self.lstore.iter_next(iter)

This mostly works, but sometimes I get:

  GtkWarning: file gtkliststore.c: line 590 (gtk_list_store_iter_next): 
assertion `GTK_LIST_STORE (tree_model)->stamp == iter->stamp' failed
   iter = self.lstore.iter_next(iter)


Any ideas/suggestions warmly appreciated.

Regards, Stuart
