# description: simplify usage of some gtk widgets<br>
# version: 2.0<br>
# author: mario<br>

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