Not capturing hidden rows in QTableWidget

leinad

Hi,
I have a method that looks at a QTableWidget and copies its contents to a clipboard which I can use later for a c/p function. The method works fine but if I hide certain rows in the table, the method still reads them and copies them to the clipboard. Below is the code. Would anyone know how I can check if a row is hidden and not copy it to the clipboard?

Thank you!

void copyTextFromTableWidgetToClipBoard()
{
QAbstractItemModel *tableModel = tableWidget_->model();
QItemSelectionModel *selectionModel = tableWidget_->selectionModel();
QModelIndexList selectedCells = selectionModel->selectedIndexes();

std::sort(selectedCells.begin(), selectedCells.end()); 

if(selectedCells.size() < 1)
    return;

QString copy_table;
QModelIndex previous = selectedCells.first();

selectedCells.removeFirst();

for (int cell = 0; cell < selectedCells.size(); cell++)
{
    QVariant data = tableModel->data(previous);
    QString text = data.toString();

    QModelIndex index = selectedCells.at(cell);
    copy_table.append(text);

    if(index.row() != previous.row())
    {
        copy_table.append('\n');
    }
    else
    {
        copy_table.append('\t');
    }

    previous = index;
}

copy_table.append(tableModel->data(selectedCells.last()).toString());
copy_table.append('\n');

QClipboard *clipboard = QApplication::clipboard();
clipboard->setText(copy_table);

}

And how do you hide the rows? QTableView::setRowHidden()? Which has a corresponding QTableView::isRowHidden()?

If you have selected cells, as per your code, I have no idea but did you test whether any hidden cells are even included in those selected? I think I would have expected not.

leinad

Thank you and yes, but I use QModelIndex. How can I convert that to get the row number?

@leinad
bool QTableView::isIndexHidden(const QModelIndex &index)?
bool QTableView::isRowHidden(int row) passing index.row()?

But did you verify whether your selectedCells() actually includes hidden rows/cells anyway?

leinad

Yes, selected cells do include hidden rows which I was unaware that it did.
I was going to try this:
QModelIndex rowNumber;
QModelIndexList selectedCells = selectionModel->selectedIndexes();
for (int cell = 0; cell < selectedCells.size(); cell++)
{
rowNumber = selectedCells[cell];
if(ui->tableWidget->isRowHidden(rowNumber.row()))
continue;
}

You are addressing the question with QTableView but I'm using QTableWidget.

QTableWidget Class

Inherits: QTableView

And in any case I previously asked you:

So why not answer that? Together with

leinad

Yes, I use
ui->tableWidget->setRowHidden( row, true );

@leinad
But if you go to the QTableWidget Class page it does not have its own setRowHidden(), does it? It inherits QTableView::setRowHidden().

In any case the answers are above.

@leinad Just to verify, print out the contents of the row when you hide it, and when you skip it.
here:
@leinad said in Not capturing hidden rows in QTableWidget:

ui->tableWidget->setRowHidden( row, true );

and here:

@leinad said in Not capturing hidden rows in QTableWidget:

if(ui->tableWidget->isRowHidden(rowNumber.row()))
continue;
}

Just to see if it's hiding and skipping the correct rows.

leinad

I did q quick test and it appears to be working, but your suggest sounds good.

@leinad I'm trying to replicate what you have on my end, can I just fill my tableWidget with random text?
