Thanks for the Reply David,Yep, we had tested it with a few of our simple apps that we had been writing on the PC before that, and the error was the same. So we went straight to the shell and started typing to see where the problem started.
Thanks for the reply, and thanks for posting your original work on the web. Without it we would be a lot farther off in trying to get this working.

Both seemed to be working fine. But once we started trying to looking PYQT we got a Seg fault... don't suppose any of you know what this means? besides it's broke :) [EMAIL PROTECTED]:~/inclinometer$ /qtopia/bin/python Python 2.4.4 (#4, Apr 11 2008, 14:25:03) [GCC 4.1.2] on linux2 Type "help", "copyright", "credits" or "license" for more information.from PyQt4 import QtGui a = QtGui.QApplication(['',"-qws"]) w = QtGui.QWidget() w.show()QPaintDevice::metrics: Device has no metric information Unrecognised metric -1095300876!I hate this kind of error. I'm sure I've seen it before. :-(See http://www.koders.com/cpp/fid5E72FF127FF66330C902165EB46C14C3BA824BD6.aspx? s=mdef%3Ainsert for the source code which prints the line. My guess is that the wrong QPaintDevice is used, that is one which doesn't implement metric() or maybe overloading doesn't work correctly.I think you're on the right track. Maybe the -qws option is not being passed through to the QApplication constructor correctly, in which case I'd pass QApplication.GuiServer as the second argument. Or perhaps, just speculating, the event loop needs to be started. Have you (Hal) tried creating and running a simple example rather than trying things in an interactive session?
