Polymorphic QSharedPointer

The Polymorphic QSharedPointer:

Click this link. qSharedPointerCast():

QSharedPointer <Switch> mySwitchTest= qSharedPointerCast<Switch>(myState);

By  calling the  staticCast() on  smart pointer:

QSharedPointer <Switch> mySwitchTest= myState.staticCast<Switch>();

The equal of the version isstatic_cast on basic pointers.

The initialized answer is:

Here,the dynamic cast use the qSharedPointerDynamicCast:

class Derived : public Base { ... };
QSharedPointer<Base> base...
QSharedPointer<Derived> derived = qSharedPointerDynamicCast<Derived>( base );

The   static_cast  is also an equivalents for  qobject_cast and const_cast.
