C++/(Qt) pointer to any object with specific method

How do I do to call a specific method present on all classes from an other (TranslationManager) class ? I simplified a lot the code. I just want to call the setTranslationText of any class from TranslationManager.

These are to take in consideration:

1. All classes have a setTranslationText method

2. We should call setTranslationText of any class from TranslationManager by using the pointer to the class

   class Interface
   {
      ...
      public:
        void setTranslationText(QString translatedString); 
   }
   
   class AnyOtherInterface
   {
      ...
      public:
        void setTranslationText(QString translatedString); 
   }
   
   ...
   
   …
   Translationmanager::Translationmanager(){
      AnyClass = Interface; // Pointer to Interface Class
      AnyClass->setTranslatioNText("Text");
   
      AnyClass = AnyOtherInterface; // Pointer to AnyOtherInterface Class
      AnyClass->setTranslatioNText("AnotherText");
   }
   
   
   …
