//$(moc) -i -o qt.moc qt.hpp

/*
  Qt requires moc in order to bind callbacks, which causes many complications.

  First, moc is not C++11-aware. Thus, all of the "public slots:" functions must
  be declared using C++98 syntax.

  Second, multiple inheritance with QObject (eg pWindow : QObject, pObject)
  seems to cause heap corruption. As such, we need to have separate classes for
  inheriting from QObject, which are defined in this file.

  Third, moc preprocessor output is required for every Q_OBJECT class. So to
  avoid needing to generate several .moc files, all QObject classes are placed
  inside this one file instead.
