|
|---|
| 35 | <p> The <a href="http://www.uk.research.att.com/vnc/">VNC</a> protocol
|
|---|
| 36 | allows you to view and interact with the computer's display from
|
|---|
| 37 | anywhere on the network.
|
|---|
| 38 | <p> To use Qt/Embedded in this way, <tt>configure</tt> Qt with the <tt>-qt-gfx-vnc</tt>
|
|---|
| 39 | option, and ensure that you also enable 16-bit display support. Run
|
|---|
| 40 | your application via:
|
|---|
| 41 | <pre>
|
|---|
| 42 | application -display VNC:0
|
|---|
| 43 | </pre>
|
|---|
| 44 |
|
|---|
| 45 | then, run a VNC client pointing at the machine that is running your
|
|---|
| 46 | application. For example, using the X11 VNC client to view the
|
|---|
| 47 | application from the same machine:
|
|---|
| 48 | <pre>
|
|---|
| 49 | vncviewer localhost:0
|
|---|
| 50 | </pre>
|
|---|
| 51 |
|
|---|
| 52 | <p> By default, Qt/Embedded will create a 640 by 480 pixel display. You
|
|---|
| 53 | can change this by setting the <tt>QWS_SIZE</tt> environment variable to
|
|---|
| 54 | another size, e.g. <tt>QWS_SIZE=240x320</tt>.
|
|---|
| 55 | <p> VNC clients are available for a vast array of display systems: X11,
|
|---|
| 56 | Windows, Amiga, DOS, VMS, and dozens of others.
|
|---|
| 57 | <p> The <a href="emb-qvfb.html">Qt Virtual Framebuffer</a> is an alternative
|
|---|
| 58 | technique. It uses shared memory and thus is much faster and smoother, but
|
|---|
| 59 | it does not operate over a network.
