[Qt-jambi-interest] QAbstractItemModel: modelAboutToBeReset and modelReset signal?

[Mathias]

Gunnar,

thanks for the info!
Sounds good.
With the 64bit-Support coming (esp. important for OS X) and a lot of smaller
improvements like these PrivateSignals, the 4.5 version seems like a great
release to look forward to... :)

Cheers from the Black Forest,
Mathias
