[pygtk] Liststore model

[Volker Helm]

Hi Steve.

This was my intention, because the query against the database is fixed, maybe modified. But the result is defined for each column.

So, first a query against the database, result a the definition of the columns including the types and the names of each column. cur.description() is really nice ;).
Second I would generate the model, but I couldn't find a way to do dynamically. This would be an object the generate the treeview dynamically, so the header, the types of gtk.ListStore()  will be defined.

Hope I made myself clear,

Volker
