Signal/Slots with PIMPL

[kwalle]

I try to use Qts Signal/Slot mechanism with private implementation (PIMPL).

My header file is build like:

class Foo : public QWidget
{
  Q_OBJECT
public:
  ...
private:
  class FooPrivate;
  FooPrivate *d;
}

class Foo : public QWidget
{
  Q_OBJECT
public:
  ...
private:
  class FooPrivate;
  FooPrivate *d;
}

To copy to clipboard, switch view to plain text mode 

My source file is build like:

Foo::FooPrivate : public QWidget
{
public:
  ...
public slots:
  void doSomething();
signals:
  void emitSomething();
}

Foo::FooPrivate : public QWidget
{
public:
  ...
public slots:
  void doSomething();
signals:
  void emitSomething();
}

To copy to clipboard, switch view to plain text mode 

Due to this private implementation, the private signals and slots are declared inside the source file and not recognized by Q_OBJECT.

Is there an other way to use the signal/slot mechanism inside a local class?

Thanks
