This creates a list store with 3 columns of following types:
1. an invalid type GDK_TYPE_PIXBUF | G_TYPE_STRING
(GTypes are ugly numbers that definitely cannot be bitwise
or-ed)
2. G_TYPE_INT
3. some random junk that happens to lie on stack after the
first two arguments

GtkTreeView is based on the Model-View-Controller pattern
thus
****************************************************************************
* *
* GtkTreeModel columns and GtkTreeView columns are *
* two unrelated sets of columns. *
* *
****************************************************************************
A tree *model* column holds one value of a specific type [in
each row]. To create a model with a pixbuf, a string, and
an int in each row, do
model = gtk_list_store_new(3, GDK_TYPE_PIXBUF, G_TYPE_STRING, G_TYPE_INT);
Now you create a view that consists of some columns and use
cell data functions or column attributte mapping to relate
the view columns to the model columns. This relation can be
arbitrary -- even none at all in the extreme case.
If you want to pack more cells (i.e., cell renderers) to one
tree *view* column, do just that (examples can be found in
many places, one recent probably not very didactic is here:
http://mail.gnome.org/archives/gtk-app-devel-list/2006-April/msg00008.html).
Please read the tree view tutorial.
