This is a generic Qt question, rather than a PyQt specific. If you perform
long taks in your application, you need to either do them in a different
thread, or poll Qt's event loop (in Python, you can do
qApp.processEvents()). If you can poll very often within your long task, the
GUI will be still responsive. Anyway, this is better answered on the
qt-interest mailing list.
