window crazing

[yuvaraj.yadav]

Hi

I hope you people will encourage me...

Still I am reading the documents ... At same time trying with sample programs...

Already Wysto told me don't use the list view to add widgets.... I don't use here after...

Sorry , I am learning slowly....here i have been trying one small sample application

Nothing displaying the Tweets...I displayed tweets in listview with somebody help..

Here i am using the Event methods to get the current window position...and i assign the width to my tweet..

please see my code.

To display the tweet

QStandardItemModel * model = new QStandardItemModel(this);
    for (int i = 0; i < 21; ++i)
    {
        QStandardItem * item = new QStandardItem;
        model->appendRow(item);
    }
    ui->listView->setModel(model);
    for (int i = 0; i < 21; ++i)
    {   Tweet * t = new Tweet(this);
        t->resize(ui->listView->size().width(), t->size().height());
        qDebug("width:%d",ui->listView->size().width());
        qDebug("Height:%d", t->size().height());
        model->item(i)->setSizeHint(t->size());
        ui->listView->setIndexWidget(model->item(i)->index(), t);
  }
}

QStandardItemModel * model = new QStandardItemModel(this);
    for (int i = 0; i < 21; ++i)
    {
        QStandardItem * item = new QStandardItem;
        model->appendRow(item);
    }
    ui->listView->setModel(model);
    for (int i = 0; i < 21; ++i)
    {   Tweet * t = new Tweet(this);
        t->resize(ui->listView->size().width(), t->size().height());
        qDebug("width:%d",ui->listView->size().width());
        qDebug("Height:%d", t->size().height());
        model->item(i)->setSizeHint(t->size());
        ui->listView->setIndexWidget(model->item(i)->index(), t);
  }
}

To copy to clipboard, switch view to plain text mode 

my event function

void MainWindow::resizeEvent( QResizeEvent *event )
{
  emit resizeView( event->size().width(), event->oldSize().width() );
}

void MainWindow::resizeEvent( QResizeEvent *event )
{
  emit resizeView( event->size().width(), event->oldSize().width() );
}

To copy to clipboard, switch view to plain text mode 

this one emit the resizeView and call the resizeData slot...

My slot code is

void MainWindow ::resizeData(int width, int oldWidth)
{
 
 qDebug("current width:%d and old width : %d", width,oldWidth);
 
  QSize itemSize;
  Tweet *aTweet;
  for ( int i = 0; i < 21; i++ ) {
    aTweet = t;
    aTweet->resize( width , aTweet->size().height() );
    itemSize = model->item(i)->sizeHint();
    itemSize.rwidth() += width - oldWidth;
    itemSize.rheight() = aTweet->size().height();
    model->item(i)->setSizeHint( itemSize );
  }
}

void MainWindow ::resizeData(int width, int oldWidth)
{

 qDebug("current width:%d and old width : %d", width,oldWidth);

  QSize itemSize;
  Tweet *aTweet;
  for ( int i = 0; i < 21; i++ ) {
    aTweet = t;
    aTweet->resize( width , aTweet->size().height() );
    itemSize = model->item(i)->sizeHint();
    itemSize.rwidth() += width - oldWidth;
    itemSize.rheight() = aTweet->size().height();
    model->item(i)->setSizeHint( itemSize );
  }
}

To copy to clipboard, switch view to plain text mode 

here i resized my tweet width according to the window width....

If i try to modify the window window size, the window is crazed(closed)...




Please help me to solve this issue
