There is obviously a conflict, but nothing that would stop the software to work, so it is a choice for the developer to filter out or not the "-bg" arguments or make them available to either QApplication or the widget. Maybe we should add a comment there?
I have fixed this issue in revision 10347. I set argc (but not Argc) to 1 so that QApplication sees only an empty command line (other than the command, itself). I prefer the simplicity of this approach for our qt_example, and I assume most Qt/PLplot GUI application developers will stick with that model where the command-line options are completely ignored by Qt and only interpreted by PLplot. However, I put additional commentary in so that if application developers want to allow both Qt options and PLplot options (say by splitting the two kinds of options by a special "--" option like startx does for its two kinds of options), and putting one kind into argc for QApplication and the other kind into Argc for PLplot, it should be straightforward for them to do so. We are now down to zero qt issues on Linux that I am aware of. :-) Alan __________________________ Alan W.
