I'm not really happy with the existing vncviewer port to QNX, and it doesn't look like there's really going to be any improvements made to the port, so I'm working on porting it myself.
The two biggest things that I'm looking for with my port to QNX are a scrollable window, and the ability to send the ctrl-alt-del key combination. I refuse to set my PC desktop to be 640x480, and even if I do, I still can't really get to the bottom of the screen because the viewer won't run fullscreen. I'm actually not concerned about the ability to send ctrl-alt-del as much as I am the scorllable window.
It's going to take me a while to do because even though I know C/C++, I don't know them very well. On top of that, the Unix source available at RealVNC.com is written for X11, whereas the Audrey needs to reference the Photon libraries, neither of which are familiar to me as I'm a Windows developer.
Right now, I'm just working on getting the source code to compile, which is a much more difficult task than what I originally assumed it would be. I don't have as much time to work on it as I would like either, which is going to make the project take longer.
If anybody else is interested in the port when I have a "usable" version, post a message here. Otherwise, I might assume that I'm only doing this for myself and will probably lose interest in the project after a week or two.
