Runtime Error

Hi, I am confused by this problem. When I run my application, a Runtime Error occurs. The following is my main.cpp

Code:

---

#include "userDB.h"
#include "manager.h"
#include "user.h"
#include <QApplication>
#include <QTextCodec>
#include <QPixmap>
 
UserDB users;  //所有已经注册的用户
User currentUser;  //当前用户
QPixmap noDishImage;  //comment this line, it works fine
 
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    QTextCodec::setCodecForTr(QTextCodec::codecForName("GB2312"));
    Manager w;
    w.show();
    return a.exec();
}

User and UserDB are two classes I write.
Why declaring global variables of my own classes the application works fine, while declaring a blobal variable of the QPixmap leads the application to crash??
Any ideas appreciated!!

You can not declare any QPaintDevice(inherited by QPixmap,QWidget), without initializing QApplication first.

change QPixmap to QPixmap*;

Code:

---

#include <QApplication>
#include <QPixmap>
 
QPixmap* noDishImage; 
 
int main(int argc, char *argv[])
{
    QApplication a(argc, argv);
    noDishImage=new QPixmap;
    return a.exec();
}

this should work

btw .. what is that Chinese comment?:)

Yes, it works fine. And I have refer to the Qt doc.
谢谢！！

uh, my teammates and I are both Chinese, so we use Chinese to comment our code.
That two Chinese comments just tell a reader that what the two global variables are used for.

and what u have written in your last post?

--->谢谢！！<---

It seems you have little knowledge of Chinese?
Well, 谢谢 means Thank you in English.
