Scrolling to a GtkListBoxRow after adding it to a GtkListBox

[Michael Gratton <mike vee net>]

Hey all,

I assume I'm missing something obvious here, but what's the right/best 
way to ensure that a GtkListBoxRow child is visible (i.e. scrolled to 
at least the bottom of the viewport) in a scrolled GtkListBox right 
after adding it? I have a GtkListBox as a child of a GtkScrolledWindow, 
and when adding rows I am connecting to the size-allocate signal of the 
GtkListBoxRow being added, and when that is triggered get the y-coord 
from the row's allocation, then set the scrolled window's vertical 
adjustment's value to that, then disconnect from size-allocate to avoid 
unwanted scrolling later if the row changes size.

This usually works, but sometimes doesn't, and so I'm trying to work 
out what a better approach is.

I assume that when it doesn't work, the problem is a race between the 
row being added and allocated vs the list box's allocation being 
adjusted and hence picked up by the scrolled window. One solution might 
be to connect to size-allocate on the list, but since multiple rows 
could be be added at the same time, it would be hard to work out which 
once should be getting scrolled to when the list's size-allocate signal 
is fired.

As I mention, connecting to size-allocate on the row usually works, but 
configure and map either don't work or don't help. Does anyone have any 
better suggestions?

Cheers,
//Mike
