QT Singleton short acces question

ploef

Hello,

I have a singleton.h file which I use so I can acces my text to speech object in all my classes without making everytime a new object. Now I was wondering if there is a way to short out this acces.

First of all the two .h files:

File:  singleton.h
template <class T>
class Singleton
{
public:
  static T* Instance()
  {
     if(!m_Instance) m_Instance =  new T;
     return m_Instance;
  }
protected:
  Singleton();
  ~Singleton();
private:
  Singleton(Singleton const&);
  Singleton& operator=(Singleton const&);
  static T* m_Instance;
};
template <class T> T* Singleton<T>::m_Instance=NULL;

File: texttospeech.h
#include <QObject>
#include "singleton.h"
class TextToSpeech : public QObject
{
  Q_OBJECT
public:
  explicit TextToSpeech(QObject *parent = 0);
  ~TextToSpeech();

  void init();
  void speak(const QString &text);
};
typedef Singleton<TextToSpeech> tts;

Every time I need to acces something of the texttospeech class I must do this:
tts::Instance()->speak("Hello Word!");

Is there a way that I can shorten the tts::Instance() ? I though as idea that I could add #define TTS tts::Instance() after the typedef in the texttospeech.h but I would like to hear other feedbacks.

Thanks in advanced..

Hi,

You can take inspiration from the qApp macro sources

Hope it helps

HI,

Thanks for the help!

I know have the following define:
#define TTS tts:Instance()

in my texttospeech.h file and it works.
