How to set visible row in QTableView?

[rakkar]

QTableView *tableViewWidget;
int from;

I want to make tableViewWidget scroll down to show the row such that 'from' is the first row displayed.

I've tried all of the following over the last half hour, without success

tableViewWidget->showRow(from);
tableViewWidget->selectRow(from);
QModelIndex modelIndex =  tableViewWidget->indexAt(QPoint(0,from));
tableViewWidget->scrollTo(modelIndex);

tableViewWidget->showRow(from);
tableViewWidget->selectRow(from);
QModelIndex modelIndex =  tableViewWidget->indexAt(QPoint(0,from));
tableViewWidget->scrollTo(modelIndex);

To copy to clipboard, switch view to plain text mode 

I traced through scrollTo, and it works (the index is valid). But the view doesn't update.

I appreciate any help.

Unless I am misunderstanding the docs,

QModelIndex modelIndex =  tableViewWidget->indexAt(QPoint(0,from));
tableViewWidget->scrollTo(modelIndex);

QModelIndex modelIndex =  tableViewWidget->indexAt(QPoint(0,from));
tableViewWidget->scrollTo(modelIndex);

To copy to clipboard, switch view to plain text mode 

Will find the index of the row that is currently at the top-left of the view and scroll to it. This should result in not much movement. I think what you wanted was something like:

QModelIndex modelIndex =  model->index(from, 0, QModelIndex());
tableViewWidget->scrollTo(modelIndex, QAbstractItemView::PositionAtTop);

QModelIndex modelIndex =  model->index(from, 0, QModelIndex());
tableViewWidget->scrollTo(modelIndex, QAbstractItemView::PositionAtTop);

To copy to clipboard, switch view to plain text mode 

i.e. find the index of the desired row and scroll to it.
