QTableView selected row not in visible area

[mstegehu]

Hello,

If, due to logic, I select a row in my table the selected row is not automaticaly scrolled to the visible area of the TableView.

// Get model index based on markerId
                        QModelIndexList indexList (m_markerProjectionModel->match (m_markerProjectionModel->index (0,0), Qt::DisplayRole, markerId, 1, Qt::MatchExactly));
                        if (1 == indexList.count ())
                        {
                            m_markersProjectionTableView->selectRow (indexList [0].row ());
                        }

// Get model index based on markerId
                        QModelIndexList indexList (m_markerProjectionModel->match (m_markerProjectionModel->index (0,0), Qt::DisplayRole, markerId, 1, Qt::MatchExactly));
                        if (1 == indexList.count ())
                        {
                            m_markersProjectionTableView->selectRow (indexList [0].row ());
                        }

To copy to clipboard, switch view to plain text mode 

How can I get the selected item always visible in the visible area?

regards,

Marcel

I never tried, but perhaps you can use a call to scrollTo :

// Get model index based on markerId
QModelIndexList indexList (m_markerProjectionModel->match (m_markerProjectionModel->index (0,0), Qt::DisplayRole, markerId, 1, Qt::MatchExactly));
if (1 == indexList.count ())
{
   m_markersProjectionTableView->selectRow (indexList [0].row ());
   m_markersProjectionTableView->scrollTo( indexList[0]); // <= ADD THIS LINE
}

// Get model index based on markerId
QModelIndexList indexList (m_markerProjectionModel->match (m_markerProjectionModel->index (0,0), Qt::DisplayRole, markerId, 1, Qt::MatchExactly));
if (1 == indexList.count ())
{
   m_markersProjectionTableView->selectRow (indexList [0].row ());
   m_markersProjectionTableView->scrollTo( indexList[0]); // <= ADD THIS LINE
}

To copy to clipboard, switch view to plain text mode 

See HERE

[waynew]

m_markersProjectionTableView->scrollTo( indexList[0]); // <= ADD THIS LINE

I would add to that:

m_markersProjectionTableView->scrollTo( indexList[0], QAbstractItemView::EnsureVisible);

m_markersProjectionTableView->scrollTo( indexList[0], QAbstractItemView::EnsureVisible);

To copy to clipboard, switch view to plain text mode 

I have similar code and it always scrolls to the selected row.

If you look at documentation, you can see this :

void QAbstractItemView::scrollTo ( const QModelIndex & index, ScrollHint hint = EnsureVisible )   [pure virtual]

void QAbstractItemView::scrollTo ( const QModelIndex & index, ScrollHint hint = EnsureVisible )   [pure virtual]

To copy to clipboard, switch view to plain text mode 

so no real need of 2nd parameter here ( only if you want to use PositionAtTop, PositionAtBottom, PositionAtCenter )
