Remote graphics over network

I wasn't aware of VNC for headless servers, so I did some research.
For generic VNC, it seems like all the success stories were on Linux, and in addition required at least a display adapter and its installed driver, even if having no monitor.For Qt, I have found The VNC Protocol and Qt for Embedded Linux which isn't helpful and anyway for Qt 4.8.
I have found references to the QVNCServer class, but none with doc later than Qt 4.8 and no file by that name in the sources of Qt 5.
But even if QVNCServer is no longer supported, this means that the project is easier than I thought.Could you point me to any article for using Qt VNC on a Windows totally headless server using Qt of any version ?
-
No I don't have such an article at hand.
As for testing the VNC backend:
- Download the Qt sources matching your version
- Build the VNC platform plugin
- Install it
- Pass
-platform vncas parameter of your application
-
Isn't the VNC platform plugin an integral part of the distribution ?
I can find no documentation later than Qt 4.8, and that also is scarce.
The VNC code for Qt 5.10 is much more voluminous than that of 4.8 and is a total rewrite, but no documentation. -
It's back since 5.9 IIRC.
QPA Parameters:
- port by default 5900
- size=WidthxHeight logical size
- mmsize=WidthxHeight physical size
- depth (8, 16, 32)
All are optional.

Which reports ?
-
4 bug reports in order of nuisance:
QTBUG-60576
QTBUG-54119 (wrongly marked as solved)
QTBUG-53119
QTBUG-51624 -
They don't seem to be related to the VNC plugin itself.
-
No, but I'm not sure I will start with the new VNC software, being basically beta tester, without direct contact with the developer.
The bug report site does not inspire me with confidence.
I have launched a query on the Interest forum, and am still waiting for anyone to answer.
