Nano-X/microwindows

Nano-X makes it possible to write applications using the framebuffer with an API similar to Xlib. There are two demo applications. To use either you must start with the nano-X server.

#nano-X &

and then the application.

#nanox_bar &

On targets with small flash, nano-X is disabled by default. You may pass

“--enable nano-X” to configure, despite the flash size, but you risk overwriting the rootfs on the target.

For further details see http://www.microwindows.org/

Embedded Qt

Embedded Qt is a small variant from the Troll Tech Cross Platform GUI toolkit. A demo is included. To start the demo enter the following:

#qthello -qws

On targets with small flash, Qt is disabled by default. You may pass “--enable qt” to configure, despite the flash size, but you risk overwriting the rootfs on the target.
