Qtopia Core 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 Qtopia Core in this way, configure Qt with the -qt-gfx-vnc option, and ensure that you also enable 16-bit display support. Run your application like this:

    application -display VNC:0

then, run a VNC client pointing 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, Qtopia Core 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.
