use scrollTo ( const QModelIndex & index, ScrollHint hint = EnsureVisible )

use scrollTo ( const QModelIndex & index, ScrollHint hint = EnsureVisible )

This will only scroll to make sure that item is visible.
But to set focus or select item. Need to call select.

listView->selectionModel()->select(listModel->index(row,column), QItemSelectionModel::Select);

listView->selectionModel()->select(listModel->index(row,column), QItemSelectionModel::Select);

To copy to clipboard, switch view to plain text mode 

Play with

QItemSelectionModel::SelectionFlags // The 2nd argument of select function

QItemSelectionModel::SelectionFlags // The 2nd argument of select function

To copy to clipboard, switch view to plain text mode 

to achive your desired focus/selection effect on the item.

You don't need to use ScrollHint hint = EnsureVisible, it is a default parameter.
This is enough:

ui->listView->scrollTo(yourRowNumber);

ui->listView->scrollTo(yourRowNumber);

To copy to clipboard, switch view to plain text mode

Try this then:

ui->listView->scrollTo(yourRowNumber, 0);

ui->listView->scrollTo(yourRowNumber, 0);

To copy to clipboard, switch view to plain text mode 

You may need to create an index for your row/column. Look at QAbstractItemModel::createIndex

And Yes, Yogesh is correct. You also need to select it as well.
