I suggest you to always keep a source copy of Qt4 somewhere, so when you have
some doubts on the internals a quick "grep" (or recoursive search in files)
can reveal you the answer.
By looking for QT_MOC_COMPAT in the sources:
- it's used to mark QT3_SUPPORT's Signals and Slots in mainline classes
- when it's used (and QT3_SUPPORT is enabled) defines those signals and slots
as "deprecated"
- it tells the "moc" program that those signals or slots are only added for
QT3_SUPPORT purposes
In the end, if you're using the QT3_SUPPORT module, some dozens of signals and
slots are added to the non-qt3-support classes too (for internal use, I
think). In that case the compiler will tell you that using those signals and
slots is 'deprecated'.
If you found such a warning, look for 'pure' Qt4 stuff and use it ;-)
