• GtkAda is the technology that lets you implement the next generation of Ada 95 GUIs in an efficient and platform-independent manner. GtkAda is available for all flavors of Unix as well as Windows platforms.

GtkAda is based on the Gtk+ toolkit which is used in the GNOME/Linux interface amongst others. In addition to providing over 100 widgets and allowing you to use portable low-level drawing primitives, GtkAda has a pluggable look-and-feel and comes with a high-level GUI builder that allows round-trip GUI generation and update.

The GtkAda widget set includes high-level widgets such as a notebook, a spreadsheet, a charting widget, etc. At the lowest level the GtkAda technology relies on either Win32 or X11 primitives (depending on the platform) to draw its widgets, which guarantees very efficient native execution.
