My problem is deeper and primarily concerns the lack of access to header files from the props file. You won't believe it, but I know what's going on, although it's a bit of a bummer. If I set my header file to a moc file, Qt suddenly doesn't see any include files. This happens with everything. moc files are treated as C/C++ headers and unfortunately don't have inherited paths from the props file. Any ideas on how to add these paths in the props file for moc as well? Currently, if I specify "local" at the very top of the paths window, it works – the moc file compiler sees these paths. But it doesn't want to respect the header file folders inherited from the moc file. How do I add an equivalent for QtMoc in the props file? I want the compiler to see the additional directories.
