The library is a contribution to GtkAda, an Ada
bindings to GTK+ toolkit. It deals with the
following issues: tasking support; custom models
for tree view widget; custom cell renderers for
tree view widget; multi-columned derived model; an
extension derived model (to add columns to an
existing model); an abstract caching model for
directory-like data; tree view and list view
widgets for navigational browsing of abstract
caching models; file system navigation widgets
with wildcard filtering; resource styles;
capturing the resources of a widget; embeddable
images; some missing sub-programs and bugfixes; a
measurement unit selection widget and dialogs; an
improved hue-luminance-saturation color model;
simplified image buttons and buttons customizable
by style properties; controlled Ada types for GTK+
strong and weak references; and a simplified means
to create lists of strings.
