VNC and Transformed driver at the same time
In the good old QtE days you were not able to use remote X11 but you can compile VNC into QtEmbedded. This VNC Graphics plugin allowed to be stacked on top of a virtual screen or a real screen driver. In Qt/E the name of the underlying driver was hardcoded. Normally it was either LinuxFB or Transformed but it was definable at compilation time.
The two magic environment flags were QWS_SIZE=240×320 and QWS_DISPLAY=VNC:Transformed:Rot270. Yesterday after a small discussion with Robert I had a look at Qtopia4’s VNC implementation. There is one issue and one improvement and they are tighlty coupled. The documentation is still pointing to the define of QtE2 and QtE3 but in contrast to QtE QtopiaCore is capable of getting stacked on top of any other graphics driver at runtime.
This should allow Trolltech to ditch the webcam approach to get a picture off the greenphone and use VNC (assuming that it actually works) instead.
