Binary Compatibility Workarounds

This page describes some workarounds for keeping binary compatibility in patch releases.

You should read the KDE reference:

Declaring a slot for private classes (d-pointer)


 class A: public QObject
 Q_PRIVATE_SLOT(d_func(), void myPrivateSlot())
/* in .cpp file */
 void APrivate::myPrivateSlot() {}
 #include "moc_a.cpp"

Pitfalls to avoid:

Don't include `a.moc`, but `moc_a.cpp` in your .cpp file

  • Q_PRIVATE_SLOT takes the complete signature of the private slot, not just its name
