Use `ui_xml` instead of local filename. (Read via pkgutil.get_data, so should work independently of installation path.) Add logo/banner from `logo.py` → `logo.png`. check-in: 9057171155 user: mario tags: trunk

Added pixbuf() creation method (from base64 stringified PNG to gdk.Pixbuf) check-in: 7b1ee3b5a6 user: mario tags: trunk
16:15
Removed gtk2.xml, only gtk3.xml packaged and modified at runtime. (It's just the minimum version= that needs adaption meanwhile.) check-in: dc0351d754 user: mario tags: trunk

#
#
# 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.
