add a find findAll method to widgets ? #77
Description
In lot of cases I'm forced to use variable for every single widget that I will modify in the future. It's specifically enoying when the components are for examples V.Html(tag="tr") from a table. I implemented a method to reach child or children of a widget using key, value pair.
def get_children(
self,
widget: Optional[v.VuetifyWidget] = None,
klass: Optional[Type[v.VuetifyWidget]] = None,
attr: str = "",
value: str = "",
id_: str = "",
elements: Optional[list] = None,
) -> List[v.VuetifyWidget]:
r"""Recursively search for every element matching the specifications.
multiple parameters can be used to search for matching elements. no error is raised if nothing is found.
Args:
widget: the widget to search into
klass: the vuetify widget class to look for . Leave empty for any.
attr: the attribute to look at. leave empty for no search
value: the value of the attr. ignored if attr is not set
elements: the list used to store found elements
Returns:
List containing all matching elements
Retrieve all children elements that matches with the given id\_.
Args:
id\_ (str, optional): attribute id to compare with.
Returns:
list with all matching elements if there are more than one, otherwise will return the matching element.

# id_ was the previous variable it should continue working in this implementation

# init the element list
elements = [] if elements is None else elements
# init the widget
widget = self if widget is None else widget
for w in widget.children:
# exit if children is not a widget (str, DOM objects.. etc)
if not isinstance(w, (v.VuetifyWidget, v.Html)):
continue
# compare the widget with requirements
# if no klass is specified, use both vuetifyWidget and Html objects
is_klass = (
isinstance(w, klass)
if klass
else isinstance(w, ((v.VuetifyWidget, v.Html)))
)
# using "niet" as default so that result is True if attr is Falsy
# "niet" is very unlikely to be used compared to None, False, "none"...
is_val = w.attributes.get(attr, "niet") == value if attr and value else True
not (is_klass and is_val) or elements.append(w)
# always search for nested elements
elements = self.get_children(w, klass, attr, value, id_, elements)
return elementsWould you see an interest to implement (and refine) this method in ipyvue ?
