Signal not found / thread communication

Dear All,
I'm new to the forum nice to be here !

My nasty problem I fight with:
(thread 1 main) - (thread 2 worker)
worker read an external device and send QByteArray back to the main-thread.
Therefore I create a signal in the worker and slot in the main with a connect(&thread,..).

I test the signal/slot within the worker-thread to see if the emit works // yes fine
but the main thread give me a

Object::connect: No such signal worker::listItemUpdate(const QByteArray ba) in reader.cpp:25

any hint is highly appreciated.

Chris

Code:

---

class worker : public QThread
...
	signals:
	void listItemUpdate(const QByteArray& ba);
 
 
class main : public QMainWindow
...
private slots:
void RlistItemUpdate(const QByteArray ba);
...
private:
worker InvThread;
 
main::main()
...
connect(&InvThread, SIGNAL(listItemUpdate(const QByteArray ba))
	, this , SLOT(RlistItemUpdate(const QByteArray ba)));

---

Code:

---

connect(&InvThread, SIGNAL(listItemUpdate(const QByteArray))
	, this , SLOT(RlistItemUpdate(const QByteArray)));

You're calling connect() with named parameters. This simply isn't right.

Thank guy's

Are you sure you don't want to sent a const reference instead of a const bytearray?
