SystemProgressDialog: Signal finished(bb::system::SystemUiResult::Type) never called

Hi.

 

I'm having problems to connect a signal from a SystemProgressDialog object to QThread derived class object.

The connect call it's:

    connect(SpinningWheelDialog , SIGNAL(finished(bb::system:Smiley FrustratedystemUiResult::Type) ) , this , SLOT(terminateNotification(bb::system:Smiley FrustratedystemUiResult::Type) ) );

 

The SpinningWheelDialog object is a SystemProgressDialog;
The class this is the QThread derived one and the connect it's invoked in the constructor of this class.

There are no error both at compilation and runtime, so i suppose the code is correct. It simply doesn't work. When a button is clicked the Dialog disappear but the slot method is not called.

 

I want the thread to be terminated when the Dialog is closed or destroyed.

Any help is appreciated.

It's advised not to derive QThread any more, take a look here...

The Thread Support section has some example code which you should easily be able to adapt to your code.
