[PyKDE] Starting a PyQt application from a console daemon

[Kevin Cureton]

While I haven't used it myself, Qt4 has support for console  
applications.

http://doc.trolltech.com/4.1/qcoreapplication.html

The list can comment on whether or not this is fully supported in PyQt.

To clarify, you want to run a daemon of some sort. The daemon then,  
depending on what signals it gets, will launch a GUI application.  
Using a fork would be appropriate in this case. Forking will create a  
separate process. That new process can run independently of the  
parent process, so it can have a Qt application loop regardless of  
what the parent process does.
