More QDataWidgetMapper problems

Message 1 in thread

Hi,

I'm wondering if anyone can tell me how to insert a row into a 
QSqlTableModel that is attached to a widget mapper. The mapper's 
currentRow() returns -1 after doing an addRow() to the table model and 
the mapper's index cannot be changed. How is it supposed to work?

Thanks,

John

I just answered my own question using the "C++ GUI Programming With Qt4" 
book.

Here's a summary for anyone else who cares:

void MyDataClass::MyDataClass(void)
{
	connect(model, SIGNAL(primeInsert(int, QSqlRecord &)), this, 
SLOT(primeInsert(int, QSqlRecord &)));
}

void MyDataClass::insertRow(void)
{
	model->setTable("Parts");
	model->insertRows(0, 1);
	
}

void MyDataClass::primeInsert(int row, QSqlRecord &record)
{
	mapper->setCurrentIndex(row);
}
