Open Source Libraries

The Simple components for Ada library provides implementations of smart pointers for automatically collected objects (using reference counting), object persistence, unbounded and bounded arrays of smart pointers, generic unbounded arrays of private objects and plain pointers, generic sets, maps, arbitrary precision arithmetic, B-trees, directed graphs, directed weighted graphs, stacks, and storage pools. It also includes table management, string editing, IEEE 754 support, and infix expression parsing tools. Implementations of some lock-free shared data structures are provided.

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.
