QList<A*> indexOf

[Moppel]

Hi,

can someone explain this compiler error below?

#include <QList>
 
class A
{
 
public:
	A(){ _list = new QList<A*>(); }
	~A(){ delete _list;}
	int indexOfChild(const A* x) const { return _list->indexOf( x, 0); }
 
private:
	QList<A*> *_list;
};

#include <QList>

class A
{

public:
	A(){ _list = new QList<A*>(); }
	~A(){ delete _list;}
	int indexOfChild(const A* x) const { return _list->indexOf( x, 0); }

private:
	QList<A*> *_list;
};

a.cpp:9: error:   initializing argument 1 of `int QList<T>::indexOf(const T&,

Why takes the conversion from 'const A*' to 'A*' place?
if T = A*
this is
int QList<A*>::indexOf(const A*&, int) const
But A*& ??

References and pointers....

Can someone enligthen me, please?

Thanks,
