Hi,
I have been porting an editor that is strongly graphics based to the new
version. Thought it would be useful to reflect some of the problems I
had with the conversion. Firstly there were a large number of small
changes. Mostly renaming due to the changes made by the Trolltech
people.
Hi,
What's the difference between
finished() and terminated() methods of a QThread ?
Thanks.

Hello Jason
First of all, is Activation.http a QObject? I think what you want to do is:
QObject.connect(self.http, SIGNAL('done(bool)'), self.loginResponseCvd)
QObject.connect is a static class method, so there's no point in calling it
on an Activation instance. When it comes to emit however,

Thanks.
Terminated means it was closed using terminate while still working.
Finished means it has finished its work.
