Multiple definition error in c++

Hi when i try to run c++ code I am getting the following error

mainwindow.h

class MainWindow
{


  public:
     MainWindow();
    ~MainWindow();
     method();
};

and

mainwindow.cpp

#include mainwindow.h
MainWindow::MainWindow(){
   //some code here

}

MainWindow::~MainWindow(){
  //some code here

}
MainWindow::method(){
  //some code here

}

when i compile this from eclipse cdt i got the error saying multiple defintion of MainWindow::method() . Is this the correct way or iam doing anything wrong. Can any one please help me what to do?

It seems that you include your header in several cpp, and it has no guard preventing from multiple includes, like pragma once or 

#ifndef MainWindow_h 
#define MainWindow_h
class MainWindow
{


  public:
     MainWindow();
    ~MainWindow();
     method();
};
#endif
