MainWindow

[amagdy.ibrahim]

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

I hope you understood me now

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

#include <QApplication>
#include <QMainWindow>
#include"mainwindow.h"
 
int main(int argc, char *argv[])
{
    /*QApplication app(argc, argv);
 
   Ui_MainWindow ui;
	QMainWindow *Widget = new QMainWindow;
   ui.setupUi(Widget);
    Widget->show();*/
	Q_INIT_RESOURCE(mdi);
	MainWindow mainWin;
    mainWin.show();
 
 
//    return app.exec();
}

#include <QApplication>
#include <QMainWindow>
#include"mainwindow.h"

int main(int argc, char *argv[])
{
    /*QApplication app(argc, argv);

   Ui_MainWindow ui;
	QMainWindow *Widget = new QMainWindow;
   ui.setupUi(Widget);
    Widget->show();*/
	Q_INIT_RESOURCE(mdi);
	MainWindow mainWin;
    mainWin.show();


//    return app.exec();
}

BTW:I know it isn't right to comment return but I commented it becuase there is an error is appeared:

min.cpp19:error 'app' undeclared (first use of this fucntion)

I hope you understood me now
