[osg-users] osgQt versioning problem

[Jannik Heller]

Hi Robert,

that's certainly an option, and it seems like the option that would place the least burden on developers. I like the idea.

Counting the lines of code in osgQt we have just under 2000 lines in implementation files, having that much code in headers shouldn't be too much of a problem.

Perhaps an osgQT/QT4 and osgQT/QT5 headers could include all the appropriate parts required, and then have 3rd party apps include which one they want, and have these set defines to select the different paths.

Not even that is necessary, I think. The osgQt headers already have #if QT_VERSION_CHECK(...) macros to select the appropriate code. Users would be able to #include < osgQt/... > and automatically get the correct code for the Qt version that their application is using.

It's a bit more work though to move that much code around, so for now I'm submitting the osgQt/Version fix. We can undo it later if the better fix comes around.
