MrDeath,

I'm also interested in knowing how this overloading works as I've tried it without success...
TIA,
Pedro.

Take any book for c++, there will be a lot of examples how to overload a operator. For debug and struct use

Code:

---

friend QDebug operator<<(QDebug out, const YourStruct &s)
{
  //...
}

---

The text stream works equal. And the place for the deklaration/definition you will find...
