The question about configure Qt Creator



  • Hello,
    I used Qt Creator to create a Qt Widget project.here is my code:
    main.cpp
    @#include <QtGui>

    int main(int argc, char *argv[])
    {
    QApplication a(argc, argv);
    QWidget widget;
    QLineEdit *lineEdit = new QLineEdit;
    QLabel *label = new QLabel;
    QVBoxLayout *layout = new QVBoxLayout;
    layout->addWidget( lineEdit );
    layout->addWidget( label );
    widget.setLayout( layout );
    widget.show();

    return a.exec&#40;&#41;;
    

    }@
    When I compiled the project,nothing happened.I don't why.
    Thank you for your attention.



  • I just copy and pasted the same code in main.cpp and its working fine.

    What steps do you follow ?



  • My Qt Creator is 2.4.1.My step is as default.Now I create an empty project and compile the code,it works well.
