Find out tablename in QStyledItemDelegate/QSqlQueryModel

[Walter]

I have a QSqlTableModel, a QTableView and a QStyledItemDelegate.

I can find out the column name in paint() this way:

QString fieldname, tablename;
const QAbstractItemModel *abstractmodel = index.model();
 
if( abstractmodel->inherits( "QSqlQueryModel"))
{
	QSqlQueryModel *model = (QSqlQueryModel *)abstractmodel;
	QSqlRecord rec = model->record();
	fieldname = rec.fieldName(col);
}

QString fieldname, tablename;
const QAbstractItemModel *abstractmodel = index.model();

if( abstractmodel->inherits( "QSqlQueryModel"))
{
	QSqlQueryModel *model = (QSqlQueryModel *)abstractmodel;
	QSqlRecord rec = model->record();
	fieldname = rec.fieldName(col);
}

To copy to clipboard, switch view to plain text mode 

Same if I use QSqlTableModel instead of for QSqlQueryModel. This part works.

But now I need to find out the tablename because when I use QSqlQueryModel I can join multiple tables and I can't identify a certain column only by the column name, I also need the table name...
