Qt4: Usage C++ templates with Q_OBJECT

There is a problem to use C++ template class which should have Q_OBJECT macros.

Using the Meta-Object Compiler (moc):
moc doesn't create moc class (qt meta info for class) for follow class declaration :

template <class T>
class SomeWidget : public SomeSubWidget {
 Q_OBJECT
public:
 SomeWidget(QWidget *parent = 0): SomeSubWidget(parent){
 }
 // for instance, wrap T class
protected:
 virtual T* component(QWidget *parent = 0) { return new T(parent); }

 T *widget;
};

Solution: devide class for two classes - with Q_OBJECT declaration and with template:
create sub class with Q_OBJECT

class SomeSubWidget : public QWidget
{
 Q_OBJECT
public:
 SomeSubWidget(QWidget *parent = 0):QWidget(parent){}
};

and when inherit it and add template:

template <class T>
class SomeWidget : public SomeSubWidget
{
public:
 SomeWidget(QWidget *parent = 0): SomeSubWidget(parent){
 }
 // for instance, wrap T class
protected:
 virtual T* component(QWidget *parent = 0) { return new T(parent); }

 T *widget;
};
