How to return a reference of a QPointer ?

[jezz]

Hi, I need to do something like this:

class Apple {
private:
  QPointer<Tree> m_tree;
public:
  Tree &tree();
}
 
Tree &Apple::tree()
{
  return m_tree;
}

class Apple {
private:
  QPointer<Tree> m_tree;
public:
  Tree &tree();
}

Tree &Apple::tree()
{
  return m_tree;
}

To copy to clipboard, switch view to plain text mode 

But the compiler says this for the line 'return m_tree':
error C2440: 'return' : cannot convert from 'QPointer<T>' to 'Tree &'

How to change the line to make it work?
Thanks.
