signal and slot passing data between a dialog and object, signal error

Hi All,
hope you can help out with this. I'm trying to connect a signal from a dialog to a object slot except it's reporting and error “QObject::connect: No such signal GameAddDialog::add_to_game_list_signal( struct symbolstruct element_to_add ) in”

My dialog is show below

Code:

---

namespace Ui {
class GameAddDialog;
}
class GameAddDialog : public QDialog
{
    Q_OBJECT
 
public:
    explicit GameAddDialog(QWidget *parent = 0);
    ~GameAddDialog();
signals:
    void add_to_Game_list_signal( struct Gamestruct element_to_add );
private slots:
    void on_pushButton_clicked();
    void on_pushButton_2_clicked();
private:
    Ui::GameAddDialog *ui;
};

---

my object is defined as

Code:

---

typedef struct Gamestruct
{
   /*name of symbol*/
   QString  name_string;
 
}GAMESTRUCT;
class GameObject : public QObject
{
    Q_OBJECT
public:
    explicit GameObject(QObject *parent = 0);
 
signals:
 
public slots:
    void add_to_Game_list_slot( struct Gamestruct element_to_add );
private:
    std::vector <struct Gamestruct> Game_list;
 
};
extern class GameObject GameObjectClass;

---

I connect the signal and slot after int the function below after I create the dialog.

Code:

---

GameAddDialog mAddDialog;
    /*connect the signals and slots*/
    QObject::connect( &mAddDialog, SIGNAL( add_to_Game_list_signal( struct Gamestruct element_to_add ) ), &GameObjectClass, SLOT( add_to_Game_list_slot( struct Gamestruct element_to_add ) ) ); ***error line
    mAddDialog.setModal( true );
    mAddDialog.exec( );

---

The error occurs on the line Ive marked ***error.

Can anyone advise? Is it something to do with the GameAddDialog not being global

You have argument names in your SIGNAL and SLOT macros, they only take the method's signature (method name and types of arguments).

Cheers,
