Sending a QCOP message with parameters also works fine, when the receiver is PyQt, e.g. e = qtpe.QCopEnvelope( QPE/Application/elan, message() ) e.writeBytes( HelloWorld! ) del e works also as expected. Now the case which does not function: The following code _should_ make a string appear on the TaskBar (it's basically the same what Global::statusMessage() does): e = qtpe.QCopEnvelope( QPE/TaskBar, message(QString) ) e.writeBytes( HelloWorld! ) del e But the only thing I get is garbage on the taskbar. The message seems to be received, but somehow the data is not marshalled or interpretated correctly. Or could it be possible (since the message is sent inside the destructor) that the corresponding char* has been deleted or overwritten before it is accessed by the QCopEnvelope?

One thing though (ya' know, some folks just can't get enough :)): Could you give me a hint how to wrap QCopEnvelope? I need it for our project since calling /opt/QtPalmtop/bin/qcop is way to slow. The issue came up on this list, once, and IIRC the problem was the support for the operator which QCopEnvelope relies on. Would it be difficult to implement QCopEnvelope using a simple class method, e.g. QCopEnvelope.post instead of the operator? There shouldn't be any problem implementing the operator by providing an __lshift__ method in the same way that __iadd__ is implemented for QSemaphore.
