C++ interfaces like in java, declaration inside a function how to make it beautiful?

Question

C++ / C#

There is a virtual class c++

class IEvent {
  public:
    virtual void onClick(int index) = 0;
};

At the moment I create it and install it like this:

struct audioAdapterArtistEvents : AdapterAudio::IEvent {
    PlaylistGUIManager &base;

    explicit audioAdapterArtistEvents(PlaylistGUIManager &base) : base(base) {};

    void onClick(int index) override {
      base.mediaServiceBase->getPlaySession()->BasePlayAudio(base.mAudioAdapter.visibleList,index);
    }
  };

  mAudioAdapter.onClickArtist(new audioAdapterArtistEvents(*this));

But it doesn’t look very nice, I would like it to be like in java, for example

mAudioAdapter.onClickArtist(new AdapterAudio.IEvent() {
     @Override
     public void onClick(int index) {
                //....
    }
});

Is it possible somehow in c++ to declare a class inside a function parameter like in java?

No.
But for stuff like this you can use lambdas :)
