It works pretty good until circa row 900, showing the cell at the top of

out of the visible area.
Try doing the scroll_to_cell in an idle_add callback.
OK, it took me a while to understand (never used idle_add :)
Thank you for your help.
I tried:
...
if (self.magaddpath != 0):
print self.magaddpath
selection = self[tv_mag_list].get_selection()
gobject.idle_add(self._scroll_to_cell, self.magaddpath)
selection.select_path(self.magaddpath)
self.on_tv_mag_list_selected()
self.magaddpath=0
def _scroll_to_cell(self, pos):
self[tv_mag_list].scroll_to_cell(pos)
This all is part of a class, hence self._scroll_to_cell inside
idle_add()
It works exactly as before, showing the row as last cell in the view
It seems that it makes his best to show it, but also tries to show
something else.
I've also read something about page_clamp() or similar, but it seems it
doesn't exist anymore for treeviews, only for adjustments.
Any other ideas?
