Again On Porting Code... Sorry :-)

Hello NG,

   knowing that I am not so good in C++ programming, could anyone please
explain me how can I convert this simple C++ lines in a Python class declaration
+ __init__ function?

Suppose that wxFoldPanelItem is a class I already have written.

class wxFoldPanel
{
private:
    wxFoldPanelItem *_item;

public:
    /** Constructor, usually not directly used by the developer. */
    wxFoldPanel(wxFoldPanelItem *item)
        : _item(item)
    {
    }

And, if you can, what does it mean this:

/** Copy operator to assign one instance to the other, this is needed because
these classes are passed as instance not by reference. */
    virtual void operator=(const wxFoldPanel &item) {
        _item = item._item;

I suppose there is a smarter way to do it in Python...

Thanks to you all.

Andrea.

You usually don't have to (or want to) do this in python. I dropped all such
things when I converted OGL. Python only has references, so trying to "undo"
the reference handling would just be confusing.

Hello Pierre,

class wxFoldPanel:
   def __init__(self, item):
       self._item = item

OK, so I have done it correctly. I just needed a confirmation from someone
that knows better than me C++ :wink:

Thank you a lot.

Andrea.
