Simple Extension for wxFileDropTarget of wxWidgets

//--------------------------------------------------------------------------
class CWxDnDSink
{
public:
    CWxDnDSink();
    virtual ~CWxDnDSink() = 0;

    virtual Result OnDropFiles(wxCoord x, wxCoord y, const wxArrayString& rFile);
};

//--------------------------------------------------------------------------
class CWxFileDropTarget : public wxFileDropTarget
{
    CWxDnDSink*     pDnDSink;

public:
    CWxFileDropTarget(CWxDnDSink* pSink);
    virtual ~CWxFileDropTarget();

    virtual bool OnDropFiles(wxCoord x, wxCoord y, const wxArrayString& rFile);
};

Then every wxWindow can inherit CWxDnDSink, and SetDropTarget with a CWxFileDropTarget object. Quite simple and useful for me since I don`t want to write new drop target every time (like the dnd sample).
