This is a C-based UI library, but type-safe for C++ compatibility. The software also comes with a WYSIWYG GUI builder.
They include tons of extra widgets like business graphics (bar, pie, and line charts), images (all standard formats), and hypertext help.
Other software in Open Interface includes international character support, multi-font support, full printer support, memory management, file I/O support as well as Windows DDE support (the latter is, of course, non- portable).
They also have a product called Nexpertobject, which is an expert systems tool intended for GUI development.
