    Question QT3 or QT4 - Why upgrade to QT4 ?

    I am just getting used (more or less) to QT3 and QT4 is released...

    Why is QT4 better ? Ease of use, features, ???

    The book programming with QT4 is unavailable on Amazon.
    Is there another site where I can buy it ?

    Qt4 is a bit more complex, so it's easier to learn Qt3, but Qt4 has a lot of new features. Like PDF & SVG support, more powerful painting engine, unit testing library, much cleaner .ui file handling, MVC paradigm, ...

    Probably such book doesn't exist yet, but you might try this.

    I'm assuming you want to use Qt in the very long term.
    Without looking at any features: Why should you not upgrade to Qt 4? If it's only that you don't know the API, I can't believe that a switch to Qt 5 would be easier...
