I don't see a reason for the first leak you highlight in your code. You should create the url using QLatin1String as this saves QString having to guess the encoding -see http://labs.trolltech.com/blogs/2008/04/28/string-theory/ for details. The second leak is due to the main IonInterface (outside your code) leaking its d-pointer. I can't see why it or your WetterComIon::Private need to be QObjects, when they don't do any QObject-type things, so I'd remove this unless I am wrong for some subtle reason. I fixed this with r1043227 but you should probably also remove the QObject inheritance from your code. - Will On 2009-10-31 14:02:05, Thilo-Alexander Ginkel wrote: > > ----------------------------------------------------------- > This is an automatically generated e-mail.
