[PyKDE] Is it possible to fake multiple inheritance with PyQt ?

[Mustafa Sakalsiz]

Hi,

You don't always need to make subclasses of QObject to emit signals.

You may use another QObject instance to emit signals.
An example: http://www.opendocs.org/pyqt/index.lxp?lxpwrap=x1807%2ehtm

or you can use QSignal, Qt Assistant have a sample.
