复制QTableView的一部分

问题描述

所以我有一个与我在这里看到的另一个问题密切相关的问题，但是当我试图在我的问题上提出问题时，我没有得到任何回答，我希望这是一个新的问题，有人可以帮助我。基本上我想简单地复制我创建的表的一部分，以便我可以将其粘贴到excel文件。这里是我有：

So I have a question very closely related to another question I've seen on here but when I tried posing my question there I got no responses, I'm hoping by asking this as a fresh question someone can help me out. Basically I want simply copy a portion of my table that I've created so that I can paste it to an excel file. Here's what I have:

    QAbstractItemModel *abmodel = ui.tableview->model();
    QItemSelectionModel *model = ui.tableview->selectionModel();
    QModelIndexList list = model->selectionIndexes();
    qSort(list);
    QModelIndex index = list.first();
    for(int i = 0; i < list.size(); i++)
{
    QModelIndex index = list.at(i);
    QString text = abmodel->data(index).toString();
    copy_table.append(text);

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

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

这将复制列精细，但是当我试图复制一行或说一个2x2子表行索引混乱，不正确地为值的行索引。任何想法？

This will copy a column fine, but when I attempt to copy a row or say a 2x2 subtable the row index gets messed up, incorrectly assigning the row index for the values. Any thoughts?

好吧，已经想出来了，对任何浪费他们的时间和看起来。

Well, already figured it out, sorry anyone that wasted their time and looked.

void TestCopyTable::on_pushButton_copy_clicked()
{
QAbstractItemModel *abmodel = ui.tableView->model();
QItemSelectionModel * model = ui.tableView->selectionModel();
QModelIndexList list = model->selectedIndexes();

qSort(list);

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

QString copy_table;
QModelIndex last = list.last();
QModelIndex previous = list.first();

list.removeFirst();

for(int i = 0; i < list.size(); i++)
{
    QVariant data = abmodel->data(previous);
    QString text = data.toString();

    QModelIndex index = list.at(i);
    copy_table.append(text);

    if(index.row() != previous.row())

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

copy_table.append(abmodel->data(list.last()).toString());
copy_table.append('\n');

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

}
