Adding GtkTreeStore columns after instantiation.

[murrayc t-online de (Murray Cumming)]

gtk_tree_store_new() and gtk_tree_store_newv() allow us to specify the
number of columns, and the column types. Is it possible to add columns
to a GtkTreeStore after that?

I also noticed that GtkTreeView does have a
gtk_tree_view_append_column() function. But I guess that each
GtkTreeView column corresponds to a GtkTreeStore column. So what governs
the mapping?
