    Default Porting from qwt-4.2.0 to qwt-5.0.2

    Hello, I am porting qt-based program from Qt3 to Qt4.
    Some classes use qwt-4.2.0.
    I thought, qwt-5 was a port of qwt-4 for qt4 and took qwt-5.0.2.
    Unfortunately, the interface (classes, enums, methods) changed completely betw. 4.2.0 and 5.0.2. Is there something like a porting guide?

    Is it possible to compile qwt-4.2.0 with Qt4?

    Thank you very much for any suggestions!

    No, but you will notice, that a Qwt4->Qwt5 port is by far not so difficult as porting from Qt3 to Qt4.
    Is it possible to compile qwt-4.2.0 with Qt4?
    No way, but you can compile Qwt 5.x with Qt3. This is not what you want, but at least you can port Qwt first before you start with Qt4.

    Hello Uwe,

    Are you developer of QWT? Should I try to make a mapping-list for the classes i portes?

    A porting guide written would be helpful.
