How to make copy of QTableWidgetItem?

Engelard

It appears to be a real problem, i can't make a copy of item from QTableWidget1 and place it in QTableWidget2.
Program runs, but in output messages:

QTableWidget: cannot insert an item that is already owned by another QTableWidget

Tried to make separated, new instance of item and assign it with first, but not working...

QTableWidgetItem *temp = ui->tableWid->item(0, 0);

@Engelard
A QTableWidgetItem has a "pointer" in it so that it knows which QTableWidget it belongs to. A given item can only belong to one table/parent.

So you cannot just "copy" a QTableWidgetItem and stuff it into another table. You must create a new, blank one, set fields one-by-one from the one you want to copy from, and then add it to the new owner.

@JonB that what i was afraid of... manually reimplement all stuff and parameters to new Item..

There is really no way to make it faster and simpler?

Edit:

Or maybe some function like inheritAllStuffFromOtherItem?

something like QTableWidgetItem::clone()? :)
Which is literally new QTableWidgetItem( *ui->tableWid->item(0,0) )

and also doesn't assign a QTableWidget (view):

QTableWidgetItem::QTableWidgetItem(const QTableWidgetItem &other)
    : rtti(Type), values(other.values), view(0),
      d(new QTableWidgetItemPrivate(this)),
      itemFlags(other.itemFlags)
{
}

@raven-worx oh, i forgot to mention that i'm must using QVector of QTabWidgetItems, so how should i treat that? Next code not working:

copyItem.append(new QTableWidgetItem(ui->tableWid->item(0, 1));

@Engelard said in How to make copy of QTableWidgetItem?:

copyItem.append(new QTableWidgetItem(ui->tableWid->item(0, 1));

this is not the code i've posted. Note the *
And as i said, for the sake of simplicity just call clone()

copyItem.append( ui->tableWid->item(0,1)->clone() );

To avoid confusion would you care to correct your second line in your earlier post above from QTableWidget to QTableWidgetItem?
