To copy to clipboard, switch view to plain text mode 

I don't know how to get all column data if one row clicked. Sample if i click row number 6. I get result

Hi,

Try something like this

switch(keyEvent->key())
    {
        case Qt::Key_C:
            if(keyEvent->modifiers() & Qt::ControlModifier)
            {
                QList<QTreeWidgetItem *> selItems =  this->selectedItems();
                QApplication::setOverrideCursor(Qt::WaitCursor);
                QString temp;
                qApp->processEvents();
                // Add header
                for(int i = 0; i < this->headerItem()->columnCount(); i++)
                    temp += this->headerItem()->data(i, 0).toString() + '\t';
                temp.remove(temp.size() - 1, 1); // remove last '\t'
                temp += '\n';
                for(int i = 0; i < selItems.size(); i++)
                {                        
                    for(int j = 0; j < selItems.at(0)->columnCount(); j++)
                        temp += selItems.at(i)->data(j, 0).toString() + '\t';
                    temp.remove(temp.size() - 1, 1); // remove last '\t'
                    temp += '\n';
                }
                temp.remove(temp.size() - 1, 1); // remove last '\n'
                QApplication::clipboard()->setText(temp);
                QApplication::restoreOverrideCursor();  
            }
            else
                QTreeWidget::keyPressEvent(keyEvent);
            break;

switch(keyEvent->key())
    {
        case Qt::Key_C:
            if(keyEvent->modifiers() & Qt::ControlModifier)
            {
                QList<QTreeWidgetItem *> selItems =  this->selectedItems();
                QApplication::setOverrideCursor(Qt::WaitCursor);
                QString temp;
                qApp->processEvents();
                // Add header
                for(int i = 0; i < this->headerItem()->columnCount(); i++)
                    temp += this->headerItem()->data(i, 0).toString() + '\t';
                temp.remove(temp.size() - 1, 1); // remove last '\t'
                temp += '\n';
                for(int i = 0; i < selItems.size(); i++)
                {                        
                    for(int j = 0; j < selItems.at(0)->columnCount(); j++)
                        temp += selItems.at(i)->data(j, 0).toString() + '\t';
                    temp.remove(temp.size() - 1, 1); // remove last '\t'
                    temp += '\n';
                }
                temp.remove(temp.size() - 1, 1); // remove last '\n'
                QApplication::clipboard()->setText(temp);
                QApplication::restoreOverrideCursor();  
            }
            else
                QTreeWidget::keyPressEvent(keyEvent);
            break;

It's part of my keyPressEvent function, I use QTreeWidget but for QTreeView will be quite similar.

Thank's for your reply.

But, I confused with your code. Btw, I created QTreeView with designer. I want get data with doubleclicked signal. I see, the parameters just QModelIndex. Can I get data with that ? Or, what signal must I use ?

So far I just retrieve data when column is clicked. Whereas I want to take data from all columns.

void Dialog::on_treeView_doubleClicked(QModelIndex index)
{
    qDebug() << "Data : " << index.model()->data(index).toString();
}

void Dialog::on_treeView_doubleClicked(QModelIndex index)
{
    qDebug() << "Data : " << index.model()->data(index).toString();
}

I Hope, you can understand my english

Well, you could create a model index for each column and pass those to the model to retrieve the data for each column, but a far better way would be to design and code your own model so you have the data stored how you want it, then you don't need the model at all - you can reference your data structure directly using index.row()

[wirasto]

Can you give me a sample code ? I tried search use google, but not lucky

[squidge]

\qt\examples\itemviews\addressbook\

You'll notice the data is stored in a QList<QPair<QString,QString>>, so the data can be referenced directly without using the data method of the model.

For example, to receive both columns for any appropriate row you would do the following:

QPair<QString, QString> pair = model.listOfPairs.at(index.row());

QPair<QString, QString> pair = model.listOfPairs.at(index.row());

To copy to clipboard, switch view to plain text mode 

Assuming listOfParis was public of course (you would probably prefer to have a method for accessing it that returned a type such as QPair<QString, QString> type)

And of course, you would have a custom structured data storage object, not QPair, but probably still in a QList<>

Hello,

This should work for single row selection

void Dialog::on_treeView_clicked(QModelIndex index)
{
    Q_UNUSED(index);
    QModelIndexList mySelection = ui->treeView->selectionModel()->selectedIndexes();
    QString data;
    foreach(QModelIndex selectedIndex, mySelection)
        data += selectedIndex.data(0).toString() + '\t';
    data.remove(data.size() - 1, 1);
    qDebug() << "Data : " << data;
}

void Dialog::on_treeView_clicked(QModelIndex index)
{
    Q_UNUSED(index);
    QModelIndexList mySelection = ui->treeView->selectionModel()->selectedIndexes();
    QString data;
    foreach(QModelIndex selectedIndex, mySelection)
        data += selectedIndex.data(0).toString() + '\t';
    data.remove(data.size() - 1, 1);
    qDebug() << "Data : " << data;
}

Perhaps this might also work

[code]
name =(model->item(temp.row(),column))->text();
[\code]
name -> QString
model -> QStandardItemModel
temp -> QModelIndex
