Qt/Embedded as a VNC Server
The VNC protocol allows you to view and interact with the computer's display from anywhere on the network.
To use Qt/Embedded in this way, configure Qt with the -vnc option, and ensure you also enable 16-bit display support. Run your application via:
application -display VNC:0
then, run a VNC client pointed at the machine that is running your
application. For example, using the X11 VNC client to view the
application from the same machine:
vncviewer localhost:0
By default, Qt/Embedded will create a 640 by 480 pixel display. You can change this by setting the QWS_SIZE environment variable to another size, e.g. QWS_SIZE=240x320.
VNC clients are available for a vast array of display systems - X11, Windows, Amiga, DOS, VMS, and dozens of others.
The Qt Virtual Framebuffer is an alternative technique. It uses shared memory and thus is much faster and smoother, but it does not operate over a network.
