"error: no matching function for call to " when overloading method of base class

[Sven]

Hi,

I cannot see which problem the compiler (g++ 4.1.2) has with my code.
Is says to me:
../poollist.cc:480: error: no matching function for call to
‘TPoolList::Append(char*)’
../poollist.cc:367: note: candidates are: void TPoolList::Append
(PoolEntryKey_t&)

And this is the related part of the code:

class TList : public TWindow {
public:
void Append( char* );
// ...
};

class TScrolledList : public TList {
// ...
};

class TPoolList : public TScrolledList {
public:
void Append( PoolEntryKEy_t& );
// ...
};

TPoolList* poolList = new TPoolList;
poolList->Append( "text" );

Can someone tell me, what the problem might be? Why is the method of
the base class invisible there?

Thanks, Sven

Read about *name hiding*. Probably in the FAQ.

(except that the FAQ example has versions of Append
that both match the parameter, so the wrong one is
silently called; at least in your example you get a
compiler error).
