Overloaded Constructors?!?

[andrea_gavana at tin.it]

 Hello NG,

   I am trying to port a useful class from wxWidgets (C++) to a pure Python/wxPython
implementation. In the C++ source code, a unique class is initialized with
2 different methods (???). This is what it seems to me. I have this declarations:

class wxFoldWindowItem
{
private:
    wxWindow *_wnd;
    int _type, _flags;
    int _leftSpacing,
        _rightSpacing,
        _ySpacing;
    int _lineWidth, _lineY;
    wxColour _sepLineColour;

public:
    enum
    {
        WINDOW = 0,
        SEPARATOR
    };

    // wxWindow constructor. This initialises the class as a wxWindow type
    wxFoldWindowItem(wxWindow *wnd, int flags = wxFPB_ALIGN_WIDTH, int ySpacing
= wxFPB_DEFAULT_YSPACING,
                     int leftSpacing = wxFPB_DEFAULT_LEFTSPACING, int rightSpacing
= wxFPB_DEFAULT_RIGHTSPACING)
        : _wnd(wnd)
        , _type(WINDOW)
        , _flags(flags)
        , _leftSpacing(leftSpacing)
        , _rightSpacing(rightSpacing)
        , _ySpacing(ySpacing)
        , _lineWidth(0)
        , _lineY(0)
    {
    };

    // separator constructor. This initialises the class as a separator
type
    wxFoldWindowItem(int y, const wxColour &lineColor = *wxBLACK, int ySpacing
= wxFPB_DEFAULT_YSPACING,
                     int leftSpacing = wxFPB_DEFAULT_LEFTLINESPACING,
                     int rightSpacing = wxFPB_DEFAULT_RIGHTLINESPACING)

        : _wnd(0)
        , _type(SEPARATOR)
        , _flags(wxFPB_ALIGN_WIDTH)
        , _leftSpacing(leftSpacing)
        , _rightSpacing(rightSpacing)
        , _ySpacing(ySpacing)
        , _lineWidth(0)
        , _lineY(y)
        , _sepLineColour(lineColor)
    {
    };

The 2 different initializations refers to completely different objects (the
first one is a wx.Window, the second one is an horizontal line). Next, there
are a lot of functions that, depending on the variable _type, return properties
of the wx.Window or of the line. I would like to keep the same names for
classes/methods, so it would be useful to have the same class with 2 different
"initializations".
Does anyone know if is there a way to achieve the same thing in Python/wxPython?
Someone else has talked about overloaded constructors, but I don't have
any idea on how to implement this kind of "constructors" in Python. Does
anyone have a small example of overloaded constructors in Python?
I have no idea... Or am I missing something obvious?

Thanks to you all.

Andrea.
