/*
 * qt_classes.hpp all the graphical classes inherited from Qt
 * Typically each class would have its own header file, but that
 * would also mean 1 MOC file pr class. Having all Qt definitions
 * in 1 files gives a couple of advantages
 * - only a single moc_qt_classes.cpp file
 * - All qt definitions in one file makes the overview easier
 *
 * The current graphical layout will change once we get a graphical 
 * designer to take a look.
