Closing KAplication

I'm sorry to post this, but I just can find a way to close the aplication.
Im trying to close the program when openDialog returns NULL.
BTW testApp is an KWizard class!
Here's the code in main.cpp:

int main(int argc, char **argv)
{ 
      .....
     
        KApplication app;
        testApp *mainWin = 0;       
        KFileDialog* openDialog;

        if (openDialog->getOpenFileName(":cfg","*") != "")
        {
    
        mainWin = new testApp();
        app.setMainWidget( mainWin );
        
        optionForm *opt; 
        opt = new optionForm(mainWin);
       
        
        mainWin->show();
        mainWin->addPage(opt,"prvi");
        mainWin->showPage(opt);
      }
      else 
        [that's the part that I don't know ] 

     return app.exec();
}

Quoted

Im trying to close the program when openDialog returns NULL.
if (openDialog->getOpenFileName(":cfg","*") != "")

So NULL or empty string?

Why not call exit(0) or just return from main?

        if (openDialog->getOpenFileName(":cfg","*") != QString::null)
        {
    
        mainWin = new testApp();
        app.setMainWidget( mainWin );
        
        optionForm *opt; 
        opt = new optionForm(mainWin);
       
        
        mainWin->show();
        mainWin->addPage(opt,"prvi");
        mainWin->showPage(opt);
        return app.exec();
      }
      else 
        return 0;
}


I think that should be ok.
I put QString::null in the if statement cuz I think you want to exit when user presses cancel, in which case I am pretty sure u are returned QString::null.

C:
printf("%10.2f", x);
C++:
cout << setw(10) << setprecision(2) << showpoint << x;
Java:
java.text.NumberFormat formatter = java.text.NumberFormat.getNumberInstance();
formatter.setMinimumFractionDigits(2);
formatter.setMaximumFractionDigits(2);
String s = formatter.format(x);
for (int i = s.length(); i < 10; i++) System.out.print(' ');
System.out.print(s);
