Moving items up and down in a QListWidget in different view

I am trying to move the listwidget item programmatically. I am able to move the listwidget successfully if the move is in current view. If i try to move the list widget item across view ( i.e Using scrollbar ), move is not working as expected. i.e List widget item is not reflecting

code snip:

void func(int fromPage, int toPage)
{
 QListWidget* expListWidget =i.next();
 QListWidgetItem* widgetItem = expListWidget->takeItem(fromPage);
 expListWidget->insertItem(toPage,widgetItem);
}

Here is an example how to move items up and down independently of where they are located:

QListWidget* lw1 = new QListWidget;

for (int i = 0; i < 500 ; i++)
{
    QListWidgetItem* item = new QListWidgetItem(QString::number(i));
    lw1->addItem(item);
}

//move from lower part to the top
QListWidgetItem* i = lw1->takeItem(400);
lw1->insertItem(0, i);

//move from the top to the lower part of the list
i = lw1->takeItem(1);
lw1->insertItem(400, i);
