GtkAda contributions

Description du projet

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.
