Removing Qt3support



  • Hi everyone,

    I am working in a project with qt3support. I would like to remove the qt3support and support only qt4. I have checked some documentation but still is not very clear.

    Could you tell me please if there is a way to convert qt3support to qt4 automatically?
    Same way as the tool qt3qt4:

    http://doc.qt.io/archives/qt-4.8/qt3to4.html#qt3to4

    Thanks in advance.

    Hi and welcome to devnet forum

    There is no real need to remove Qt3 nor Qt4 support. We have already Qt5. The different lower version support is for compatibility and should help to adopt newer versions.



  • Hi Koahnig.

    I am not sure if I understand you correctly. Do you mean I can compile a project with q3support libraries with a qt5 compiler?

    Actually, I want to upgrade my project to qt5, but I don´t think qt5 recognize libraries like Q3HBoxLayout.

    Thanks for your time.

    There's no Qt compiler. Qt is a C++ framework. And no, the Qt3Support module is only available in Qt 4 as a transition helper. Update your code to get rid of it.
