Sorting a TreeView with Glade/GtkBuilder

[Craig <weberc2 gmail com>]

Hello,

I was wondering how I could sort a liststore-based treeview in glade? I've
already set all columns' sort column id, but that apparently doesn't
initiate the sorting behavior.

Basically, I have a boolean/toggle column and then a text column and I want
to sort by the toggle column. Any suggestions?

Thanks,
Craig
