Question on checkboxes and associated state

[matt-grain]

Hi,

Assuming I have some pc.checkbox sharing the same State and I want to remember which one was checked. how can I linked the is_checked attribute to a fined-grained detail of my State ?

Like:

class MultichoiceState(QuestionnaireState):

    multichoice_state: Dict[int, List[str]] = {}
    checked: bool = False
    last_idx: int = 0

    # @pc.var
    def checked(asnwer: str) -> bool:
        return answer in self.multichoice_state[self.last_idx]

    def add_selected(self, idx: int, answer: str) -> None:

        self.last_idx = idx
        logger.debug(f"Adding answer {answer} for multichoice question {idx}")

        if idx not in self.multichoice_state:
            self.multichoice_state[idx] = []
        self.multichoice_state[idx].append(answer)

def c_multichoice_checkbox(details: QuestionModel) -> pc.Component:
    return pc.form_control(
        pc.wrap(
            pc.foreach(QuestionnaireState.answers_list[details.id], lambda answer: c_multichoice_checkbox_item(answer, details)),
        )
    )

def c_multichoice_checkbox_item(answer: str, details: QuestionModel) -> pc.Component:
    """_summary_

    Args:
        details (QuestionModel): _description_

    Returns:
        _type_: _description_
    """
    return pc.flex(
        pc.checkbox(
            answer,
            is_checked=MultichoiceState.is_checked(details.id, answer),  <-- doesn't work
            on_change=lambda: MultichoiceState.add_selected(details.id, answer),
        ),
    )

Thanks !

ok I found a way but yeah any to attach a State method with parameters to an attribute which expects a bool as a result would be interesting!
