Gtk Widget Server
The SLgtk package binds the GIMP Toolkit, also known as Gtk, to the S-Lang scripting language. It was created with the SLIRP code generator, and provides an importable module which makes most of Gtk and its constituent libraries callable directly from S-Lang scripts.
With SLgtk the S-Lang programmer now has access to a powerful, cross-platform widget set for creating sophisticated graphical user interfaces (GUIs). The package also includes bindings to GtkExtra, which are used in the vwhere visualization and filtering guilet, as well as a gdk-pixbuf loader for the FITS image file format widely used within astronomy, and an easy-to-use but powerful image compositing, display, and output tool.
Documentation for SLgtk is available in several formats:
