Trying to connect a pair of mutually exclusive radio buttons to slots in a different class.
Signals originate from class EnterLog when a radio button is clicked and should be received in ControlDB. The slot functions are defined as public slots in ControlDB.
Here is the code in ControlDB:

Qt Code: 
  1. public slots:
  2.     void setSingleModeEdit();
  3.     void setSingleModeEntry();
To copy to clipboard, switch view to plain text mode 

Qt Code: 
  1. void ControlDB::setSingleModeEdit() {
  2.     qDebug() << "single display mode changed to EDIT";
  3.    QSqlDatabase db = QSqlDatabase::database(ctrlConn);
  4.     QSqlQuery query(db);
  5.     query.prepare("UPDATE preferences set defaultSingleView = ?");
  6.     query.addBindValue("EDIT");
  7.     query.exec();
  8. }
  9.  
  10. void ControlDB::setSingleModeEntry() {
  11.     qDebug() << "single display mode changed to ENTRY";
  12.    QSqlDatabase db = QSqlDatabase::database(ctrlConn);
  13.     QSqlQuery query(db);
  14.     query.prepare("UPDATE preferences set defaultSingleView = ?");
  15.     query.addBindValue("ENTRY");
  16.     query.exec();
  17. }
To copy to clipboard, switch view to plain text mode 

Here is the code in EnterLog:

Qt Code: 
  1. ControlDB ctrl;
  2.     connect(ui->rbEdit, SIGNAL(clicked()),  &ctrl,  SLOT(setSingleModeEdit()));
  3.     connect(ui->rbEntry, SIGNAL(clicked()),  &ctrl,  SLOT(setSingleModeEntry()));
To copy to clipboard, switch view to plain text mode 

The problem is, the signals don't get received. What am I doing wrong here?
