Okay, it's seems like I'm missing something here:

Qt Code: 
  1. #include <QString>
  2. #include <iostream>
  3.  
  4. class TestItem
  5. {
  6. public:
  7.     TestItem(const QString &value)
  8.     {
  9.         m_value = value;
  10.     }
  11.  
  12.     QString value() const
  13.     {
  14.         return m_value;
  15.     }
  16.  
  17.     bool operator==(const TestItem &other) const
  18.     {
  19.         return this->value() == other.value();
  20.     }
  21.  
  22. private:
  23.     QString m_value;
  24. };
  25.  
  26. int main(int argc, char *argv[])
  27. {
  28.     TestItem *one = new TestItem("abc");
  29.     TestItem *two = new TestItem("abc");
  30.  
  31.     if(one == two)
  32.         std::cout << "Match";
  33.     else
  34.         std::cout << "No Match";
  35.  
  36.     return 0;
  37. }
To copy to clipboard, switch view to plain text mode 
This returns ALWAYS "No Match". But if I create the objects on the stack and not on the heap it works:
Qt Code: 
  1. TestItem one("abc");
  2. TestItem two("abc");
To copy to clipboard, switch view to plain text mode 
What do I have to do to make it work with heap initialized objects ? Thank you.
