      • setRequiredIndicatorVisible

        public void setRequiredIndicatorVisible​(boolean required)

        Description copied from interface: HasValue

        Sets the required indicator visible or not.

        If set visible, it is visually indicated in the user interface.

        The method is intended to be used with Binder which does server-side validation. In case HTML element has its own (client-side) validation it should be disabled when setRequiredIndicatorVisible(true) is called and re-enabled back on setRequiredIndicatorVisible(false). It's responsibility of each component implementation to follow the contract so that the method call doesn't do anything else than show/hide the "required" indication. Usually components provide their own setRequired method which should be called in case the client-side validation is required.

        Specified by:

        setRequiredIndicatorVisible in interface HasValue<AbstractField.ComponentValueChangeEvent<DatePicker,​LocalDate>,​LocalDate>

        Specified by:

        setRequiredIndicatorVisible in interface HasValueAndElement<AbstractField.ComponentValueChangeEvent<DatePicker,​LocalDate>,​LocalDate>

      • isRequired

        public boolean isRequired()

        Determines whether the datepicker is marked as input required.

        This property is not synchronized automatically from the client side, so the returned value may not be the same as in client side.

        Returns:

        true if the input is required, false otherwise
