* BtSignal
22
* The purpose of this class is to emit Qt signals for other classes
23
* that are not derived from QObject. It can be used as a member
24
* variable of those classes.
25
*
26
* There are some classes it is not possible to derive from QObject and
27
* have the signals work. Certain multiple inheritance classes which cannot
28
* have QObject as the first derived class, cannot use Qt signals.
