QProcess in a QThread

[Dusdan]

afaik QThreads are not QObjects in Qt3, so you can't emit signals and activate slots. I think you have to derive from both QThread and QObject if you need this features, but be careful.

in Qt4, instead, QThreads are Qobjects (so they have signals and slots) and they have their own event loop.

QProcess is an event loop driven class, it can only be used in the main thread (event loop thread)

You could use a Thread and system() to start the external player
