# Wrappers around gtk methods. The TreeView method .columns() allows
# to fill a treeview. It adds columns and data rows with a mapping
# dictionary (which specifies many options and data positions).
#
# The .tree() method is a trimmed-down variant of that, creates a
# single column, but has threaded entries.
#
# With the methodes .app_state() and .app_restore() named gtk widgets
# can be queried for attributes. The methods return a saveable dict,
# which contain current layout options for a few Widget types. Saving
# and restoring must be handled elsewhere.
