Microwindows is an Open Source project aimed at bringing the features of modern graphical windowing environments to smaller devices and platforms. Microwindows allows applications to be built and tested on the Linux desktop, as well as cross-compiled for the target device. Microwindows' genesis was with the NanoGUI project, and has now been combined into a single distribution. The Win32/WinCE API implementation is known as Microwindows, and the Xlib-like API implementation is known as Nano-X.
