    Hello!
    I’m using C4droid and learning qt for the first time. I just want to know if:
    A. Could I still use qt 3 or qt 4 gui and programming examples? The reason I ask because I typed in this basic of all codes example
    [Code]
    #include <qapplication.h>
    #include <qlabel>

    int main(int argc, char *argv[])
    {
    QApplication app(argc, argv);
    QLabel *label = new QLabel("Hello Qt!", 0);
    app.setMainWidget(label);
    label->show();
    return app.exec();
    }
    [/Code]
    And got this Message:

    //No such file or directory #include <qapplication.h>

    I even tryed to remove the dot h and still the same results

    question B.

    Where can I get all the examples on qt 5.3 Gui desidn and programming and also tutorials on how to intergrate c++ code with qml code also
    Thank You
    AO!

    P.s. do I need to purchase the full version for all this?

      Hi and welcome to devnet,

      For your question A, use

      @
      #include <QApplication>
      #include <QLabel>
      @

      Though the basics are the same, Qt 3 examples might contain classes long gone since Qt 4. However most Qt 4 example translate easily to Qt 5.

      For question B, Qt's documentation and sources.

      What purchase are you asking about ? c4droid ?

            For these two questions, you should rather contact the c4droid developer(s)
