Qt5 changes

[M. Gronle]

Some methods are changed in Qt5. One example ist the signature of the connectNotify and disconnectNotify method. These methods need to be checked. For more info see http://blog.qt.digia.com/blog/2012/06/22/changes-to-the-meta-object-system-in-qt-5/

• connect / disconnect with new Qt5 style:

Counter a, b;
QObject::connect(&a, &Counter::valueChanged,
                 &b, &Counter::setValue);

a.setValue(12);     // a.value() == 12, b.value() == 12
b.setValue(48);     // a.value() == 12, b.value() == 48

(see http://doc.qt.io/qt-5/signalsandslots.html)

• .toLatin1().data() --> .toLatin1().constData(), if string should not be changed

Closed, since ticket is overdue and too unspecific.

We are now at Release 4.2. and QT5 is well integrated. I do assume that this ticket can now be seen as resolved.
