Tidy up top level namespace of `WeasWidget`?

[ltalirz]

The top level namespace of WeasWidget is rather crowded (30+ attributes)

https://github.com/superstar54/weas-widget/blob/43d39f71088af5710186216ff40858ea368c8132/src/weas_widget/__init__.py#L15

Perhaps it would make sense to group some of those together and nest them.

Also, it appears there are some traitlets while other things are manipulated with set_ methods, and to me as a new user it is not obvious why.

Thanks, @ltalirz, for the great valuable feedback and suggestions on enhancing the code. I will try to reply to some of them now, and others later once I have a clearer idea.

Indeed, there are too many attributes on the top level, and it better to group and nest them. But I need to look into the widget framework, anywidget, and see if it supports traits within nested namespaces.

My recommendation would be to wrap the widget class and expose the _repr_mimebundle_ (what displays the actual widget), and encapsulate the anywidget instance from end users. You can then proxy assignment to properties with getter/setter patterns:

class Wrapper:

    def __init__(self, *args, **kwargs):
        self._widget = WeasWidget(*args, **kwargs)

    @property
    def value(self):
        return self._widget.value

    @value.setter
    def value(self, update):
        self._widget.value = update

    def _repr_mimebundle_(self, *args, **kwargs):
        return self._widget._repr_mimebundle_(*args, **kwargs)

FWIW, I've been exploring trying to reduce the API surface area of AnyWidget, but this complexity is inherited from (and meant to expose) the API from ipywidgets.Widget familiar to Jupyter Widgets developers.

@manzt, thanks for the suggestion; it's very helpful! I made some adjustments to ensure compatibility with ipywidget 7.x.

def _repr_mimebundle_(self, *args, **kwargs):
    # if ipywdigets > 8.0.0, use _repr_mimebundle_ instead of _ipython_display_
    if hasattr(self._widget, "_repr_mimebundle_"):
        return self._widget._repr_mimebundle_(*args, **kwargs)
    else:
        return self._widget._ipython_display_(*args, **kwargs)

@manzt One issue I notice with the _repr_mimebundle_ method is that I can not embed the widget into the HBox or VBox from ipywidgets.

Thus, I decide to wrapper the base widget by inheriting the HBox

class Wrapper(HBox):

    def __init__(self, *args, **kwargs):
        self._widget = WeasWidget(*args, **kwargs)
        super().__init__(children=[self._widget])

    @property
    def value(self):
        return self._widget.value

    @value.setter
    def value(self, update):
        self._widget.value = update
