[править] The VNC Protocol and Qtopia Core

VNC (Virtual Network Computing) software makes it possible to view and interact with one computer (the "server") from any other computer or mobile device (the "viewer") anywhere on a network.

To run a Qtopia Core application using the VNC protocol, the Qtopia Core library must be configured and compiled with the -qt-gfx-vnc option:

 cd path/to/Qtopia/Core
 ./configure -qt-gfx-vnc
 make

Then start a server application (i.e. construct a QApplication object with the QApplication::GuiServer flag or use the -qws command line parameter. See the running applications documentation for details). When runnng the application, use the -display option to specify the VNC server's driver. Пример:

 cd path/to/Qtopia/Core/examples/widgets/analogclock
 ./analogclock -qws -display VNC:0

To interact with the application over the network, run a VNC client pointing to the machine that is running the server application. VNC clients are available for a vast array of display systems: X11, Windows, Amiga, DOS, VMS, and dozens of others. For example, using the X11 VNC client to view the application from the same machine:

 vncviewer localhost:0

Qtopia Core will create a 640 by 480 pixel display by default. Alternatively, the QWS_SIZE environment variable can be used to set another size, e.g. QWS_SIZE=240x320.
