sending image one class to another class

when sending the image from one class to another class application is crashing..


Code..

Code:

---

if(http_id == id && http->lastResponse().statusCode() == 200)
    {
        QPixmap image;
QCache<QString,QPixmap>imageCache;
 
        QByteArray imagedata = buffer->data();
        image.loadFromData(imagedata);
 
            imageCache.insert(requestByEntry.key(id),&image);
          Form f;
        f.set(*imageCache[URL]);
        buffer->close();
    }

---

Code:

---

void Form::set( const QPixmap image)
{
        m_ui->label->setPixmap(image);
        this->show();
 
}

You are storing a pointer to a local object that gets destroyed when you leave the block of code. Store objects instead of pointers to them.

Hi

When i am running my application , In console i am getting

QWaitCondition: Destroyed while threads are still waiting


Then application is automatically closed..

I am using http links in my code..

if i use the QmessageBox ,that time is not showing , and application is not closed..

Code:

---

m_ui->setupUi( this );
    m_ui->blockbutton->hide();
  m_ui->callbutton->hide();
  m_ui->followbutton->hide();
  m_ui->retweetbutton->hide();
 
//QMessageBox::information(0,"get image function",QString("url link got"));
    m_ui->userName->setText(""+str);
   m_ui->userStatus->setHtml(""+str2);
   m_ui->label->setPixmap(image);
   //m_ui->userImage->setPixmap(image);
 
   m_ui->label->setMouseTracking(true);
  m_ui->label->installEventFilter(this);
m_ui->callbutton->setIcon(QIcon("../Image/all.png"));
  m_ui->blockbutton->setIcon(QIcon("../Image/65.png"));
  m_ui->followbutton->setIcon(QIcon("../Image/follow.png"));
  m_ui->retweetbutton->setIcon(QIcon("../Image/68.png"));

if i disable the message box that time application is closed

Do you use threads in your application?

No, I didn't use the threads..


Recently I used thead in above mentioned function..

QThread::wait(5000);

But nothing happened...
