list view item problem..

[addu]

Hi Friends..

I am having some number of items in my list....

That items i am going to display in list view.....

But it is showing half of the number of items only ...remaining items are empty...

QStandardItemModel *model = new QStandardItemModel;
for(int i =0;i<list.size();i++)
{
 
  QStandardItem *item = new QstandardItem;
  model->appendRow(item);
 
}
ui->listView_2->setModel(model);
for(int i =0;i<list.size();i++)
{
   statusUser = list.takeFirst();
                 // QMessageBox::information(0,"name",QString(statusUser->user.name));
                    t = new Tweet(statusUser->user.name,statusUser->status.text,statusUser->user.profileImageUrl);
                    model->item(i)->setSizeHint(t->size());
                    t->resize(ui->listView_2->size().width()+50, t->size().height());
                    ui->listView_2->setIndexWidget(model->item(i)->index(), t);
}

QStandardItemModel *model = new QStandardItemModel;
for(int i =0;i<list.size();i++)
{

  QStandardItem *item = new QstandardItem;
  model->appendRow(item);

}
ui->listView_2->setModel(model);
for(int i =0;i<list.size();i++)
{
   statusUser = list.takeFirst();
                 // QMessageBox::information(0,"name",QString(statusUser->user.name));
                    t = new Tweet(statusUser->user.name,statusUser->status.text,statusUser->user.profileImageUrl);
                    model->item(i)->setSizeHint(t->size());
                    t->resize(ui->listView_2->size().width()+50, t->size().height());
                    ui->listView_2->setIndexWidget(model->item(i)->index(), t);
}

How do solve this problem...

It's because of takeFirst() method. It takes the first element so it means it removes it from the list. Let's say you have 20 items at the begining then:
1. first loop pass:
i = 0,
size() = 20
2. second loop pass:
i = 1
size() = 19

...
10.
i = 9;
size() = 11;

11.
i = 10;
size() = 10
end of loop.

Use .at(i) instead.

Thanks

I read the documents....Your way is exactly correct..

But for me ...,Qt showing no member named as at ,if i use list.at[i]..

here i descibe the full function.

void Widget::DisplayList(QLinkedList<Returnables::StatusUser*> list, QString header)
 {
         Returnables::StatusUser *statusUser =NULL;
 
                model = new QStandardItemModel(this);
                for(int i=0;i<=list.size();i++)
                 {
                  //QMessageBox::information(0,"",QString::number(i),QString::number(list.size()));
                 QStandardItem *item = new QStandardItem;
 
                  model->appendRow(item);
                    }
               ui->listView_2->setModel(model);
 
                for(int i=0;i<=list.size();i++)
                {
                    statusUser = list.at(i);
                 //QMessageBox::information(0,"name",QString(list[i]));
                    t = new Tweet(statusUser->user.name,statusUser->status.text,statusUser->user.profileImageUrl);
                    model->item(i)->setSizeHint(t->size());
                    t->resize(ui->listView_2->size().width()+50, t->size().height());
                    ui->listView_2->setIndexWidget(model->item(i)->index(), t);
                 }
 }

void Widget::DisplayList(QLinkedList<Returnables::StatusUser*> list, QString header)
 {
         Returnables::StatusUser *statusUser =NULL;

                model = new QStandardItemModel(this);
                for(int i=0;i<=list.size();i++)
                 {
                  //QMessageBox::information(0,"",QString::number(i),QString::number(list.size()));
                 QStandardItem *item = new QStandardItem;

                  model->appendRow(item);
                    }
               ui->listView_2->setModel(model);

                for(int i=0;i<=list.size();i++)
                {
                    statusUser = list.at(i);
                 //QMessageBox::information(0,"name",QString(list[i]));
                    t = new Tweet(statusUser->user.name,statusUser->status.text,statusUser->user.profileImageUrl);
                    model->item(i)->setSizeHint(t->size());
                    t->resize(ui->listView_2->size().width()+50, t->size().height());
                    ui->listView_2->setIndexWidget(model->item(i)->index(), t);
                 }
 }
