Passing JS new operator to Brython !?

[BobSquarePants]

Hi everyone,

I would like to call a JS library trough Brython.

in my previous JS code I had

var IcoExt = L.Icon.extend({
    options: {
    shadowUrl: 'shadow.png',
    iconSize:     [32, 32],
    shadowSize:   [0, 0],
    iconAnchor:   [16, 31],
    shadowAnchor: [4, 62],
    popupAnchor:  [0, -30]
       }
    });

var pink = new IcoExt({iconUrl: 'Pink.png'});

So I don't really understand the last line var pink = new POI...
I believe it create an instance of POIcons and push {iconUrl: 'Pink.png'} into the dict options ?
not clear.., I've diged on www but found nothing conclusive.

The first part is easy to translate to Brython/Python

IcoExt = window.L.Icon.extend({
    'options': {
        'shadowUrl': 'static/map/trans.png',
        'iconSize':     [32, 32],
        'shadowSize':   [0, 0],
        'iconAnchor':   [16, 31],
        'shadowAnchor': [4, 62],
        'popupAnchor':  [0, -30]}
        })

But the second (related to new operator) doesn't work

pink = IcoExt({'iconUrl': 'Pink.png'})

give me:

Exception: : can't convert undefined to object

Any ideas ?

Thanks.

A search on "Javascript new" returns this page.

Brython documentation about using Javascript objects explains that Javascript constructors used in Brython code have a method jsobj.new(args) which is the equivalent of Javascript new jsobj(args).
