This is my very unfinished, very much in progress fork of http://www.viksoe.dk/code/windowless1.htm DirectUI is a UI framework for Windows, in C++. It's not an object-oriented wrapper around win32 functions like e.g. MFC. It doesn't use standard Windows controls (well, except edit control) but instead custom paints the controls on a single HWND window. This is needed to achieve modern UI effects like transparency. The original DirectUI was a very promising project but apparently was abandoned in 2005.
