GtkTreeModelSort

[Stuart Jansen <smj8 email byu edu>]

I've been fairly impressed with the new tree CMV design so far. However,
I'm having a hard time using the GtkTreeModelSort and modifying the
data.

Let me see if I've got this right:
Because there is no way to access the data once it is put into a
GtkListStore or GtkTreeStore, a seperate copy must be maintained. Like
in gtk-demo were editable values are stored ina a GArray. (Can I just
say that not being able to read the stored values is a _real_ pain?)

To avoid changing the order of the rows in the GtkListStore, I can't
just sort the GtkTreeModel (actually GtkListStore) but must wrap it in a
GtkTreeModelSort. (With the advantage that I can define sort functions
for individual columns.)

I'm doing that and can edit/add rows without a problem. I'm having real
trouble removing rows, however. Could someone give at least a generally
description or better (bless your heart) example code describing the
correct way to use a GtkTreeModelSort?
