    Default Re: MainWindow

    I took the code of mainwindow.cpp,mainwindow.h,mdichild.cpp,mdi.h and main (copy+paste) ypu can see it on http://doc.trolltech.com/4.2/mainwindows-mdi.html

    Then after running the code this errors or warnings appeared and I don't know the reasons:
    Collect2:Id returned 1 exit status
    mingw32-make[1]:***[release/Main3.exe]Error1
    mingw32-make[1]:Leaving directory 'E:/QT/4.4/Main3'
    mingw32-make:***[release] Error2

    tmp/obj/release_shared/main.o(.text +0*66):main.cpp:undifiened reference to qInit Rescources_mdi()
    BTW:I indcluded the two header files
    I wrote this code in the main
    Qt Code:
    1. #include <QApplication>
    2. #include <QMainWindow>
    3. #include"mainwindow.h"
    4.  
    5. int main(int argc, char *argv[])
    6. {
    7. /*QApplication app(argc, argv);
    8.  
    9.   Ui_MainWindow ui;
    10. QMainWindow *Widget = new QMainWindow;
    11.   ui.setupUi(Widget);
    12.   Widget->show();*/
    13. Q_INIT_RESOURCE(mdi);
    14. MainWindow mainWin;
    15. mainWin.show();
    16.  
    17.  
    18. // return app.exec();
    19. }
    To copy to clipboard, switch view to plain text mode 
    BTW:I know it isn't right to comment return but I commented it becuase there is an error is appeared:
