    Question Porting Qt project from 3.3 to 4.5

    I have a zip of Qt 3.3 project and now I have installed qt 4.5 with new Qt creator. I tried to open the project with new qt creator, but it did not convert the 3.3 project to 4.5 project.

    And then I referred to Qt docs and tried with the tool "qt3to4", but still I'm not able to port it.

    Can anyone plz tell me the steps for porting a qt 3.3 project to qt 4.5 project ?

    Thank you.

    you have to take one class at a time approach. first make a list of all the qt classes that the qt3.3 application is using..
    then filter out those qt classes which have changed in qt4. then apply the relevent code changes
