C++, Typedef a Static getInstance function

I Have this singleton "TextureHandler" Class which works fine using this "TextureHandler::getInstance()->functionName()", But... what i want to do is making a typedef "TxHandler" for the getInstance() function, so i can use it like this "TxHandler->functionName()", But I'm getting this error: expected initializer before 'TxHandler'.

#ifndef TEXTUREHANDLER_H
#define TEXTUREHANDLER_H

#include <SDL.h>
#include <SDL_image.h>
#include <SDL_ttf.h>
#include <iostream>
#include <string>
#include <map>
#include "Defs.h"

// Engine's texture handler class
class TextureHandler
{
    // private constructor for singleton
    TextureHandler() {}
    static TextureHandler* instance;

    // textures string map
    map<string, SDL_Texture*> tMap;

    public:
        // getInstance singleton function
        static inline TextureHandler* getInstance()
        {
            if(instance == NULL)
            {
                // create a pointer to the object
                instance = new TextureHandler();
                return instance;
            }
            return instance;
        }

        bool load(SDL_Renderer* renderer, string id, const char* filename);
        bool loadText(SDL_Renderer* renderer, string id, const char* text, TTF_Font* font, SDL_Color color);
        void render(SDL_Renderer* renderer, string id, int x, int y, int w=0, int h=0, int center=0, SDL_Rect* clip=NULL, SDL_RendererFlip flip=SDL_FLIP_NONE);
        void free(string id);
        int getWidth(string id);
        int getHeight(string id);
};

// TextureHandler instance typedef
typedef TextureHandler::getInstance() TxHandler;

#endif
