copy selected rows from QTableView to another table

[d_stranz]

As I count it, you have 8 or 9 pointers being retrieved or used in one method call or another, and not one of them is ever checked to see if it is actually a valid pointer. Nor do you ever check to see if the model indexes you are throwing around are valid. Who knows where it could be failing? Your code certainly doesn't.

Use QStandardItemModel as the model for your second table. For each item on the list of selected items, create a QStandardItem using the string retrieved from the selected item using its QModelIndex::data() method. Insert this new QStandardItem into the model at the appropriate place. If you assign the QStandardItemModel to your second table view, the view will automatically update as the model is changed.

You will have to decide whether you want to clear the second model with each new copy and paste, or whether new items are added to the end of the model.
