To copy to clipboard, switch view to plain text mode 

It crashes whenever I try to insert my data into the tablewidget. Here's the debugger output and error message:

Assuming you don't have code elsewhere that creates table widget items, then

ui->tableWidgetScenarios->item(x,y)->setText(rowData[y]);

ui->tableWidgetScenarios->item(x,y)->setText(rowData[y]);

To copy to clipboard, switch view to plain text mode 

tries to access an item that does not exist. I.e. item(x, y) returns 0 and you are then calling a method on a null pointer.

See QTableWidget::setItem().
