Hello, I tried http://diotavelli.net/PyQtWiki/Using%20a%20Custom%20Protocol%20with%20QtWebKit (I attached the code). Unfortunately I do not see anything on the page after clicking the link with the new protocol. Has anything changed or is it a bug in the version I used (PyQt 4.8.3, sip 4.12.1) ?
Regards Henning
