Method Detail

setValue

public void setValue(LocalDateTime value)

Sets the selected date and time value of the component. The value can be cleared by setting null.

The value will be truncated to millisecond precision, as that is the maximum that the time picker supports. This means that AbstractField.getValue() might return a different value than what was passed in.

Specified by:

setValue in interface HasValue<AbstractField.ComponentValueChangeEvent<DateTimePicker,LocalDateTime>,LocalDateTime>

Overrides:

setValue in class AbstractField<DateTimePicker,LocalDateTime>

Parameters:

value - the LocalDateTime instance representing the selected date and time, or null

setReadOnly

public void setReadOnly(boolean readOnly)

Description copied from interface: HasValue

Sets the read-only mode of this HasValue to given mode. The user can't change the value when in read-only mode.

A HasValue with a visual component in read-only mode typically looks visually different to signal to the user that the value cannot be edited.

Specified by:

setReadOnly in interface HasValue<AbstractField.ComponentValueChangeEvent<DateTimePicker,LocalDateTime>,LocalDateTime>

Specified by:

setReadOnly in interface HasValueAndElement<AbstractField.ComponentValueChangeEvent<DateTimePicker,LocalDateTime>,LocalDateTime>

Parameters:

readOnly - a boolean value specifying whether the component is put read-only mode or not

setLabel

public void setLabel(String label)

Sets the label for this field.

Specified by:

setLabel in interface HasLabel

Parameters:

label - the String value to set

getLabel

public String getLabel()

Gets the label of this field.

Specified by:

getLabel in interface HasLabel

Returns:

the label property of the date time picker

setDatePlaceholder

public void setDatePlaceholder(String placeholder)

Sets a placeholder string for the date field.

Parameters:

placeholder - the String value to set

getDatePlaceholder

public String getDatePlaceholder()

Gets the placeholder string of the date field.

Returns:

the placeholder property of the date picker

setTimePlaceholder

public void setTimePlaceholder(String placeholder)

Set a placeholder string for the time field.

Parameters:

placeholder - the String value to set

getTimePlaceholder

public String getTimePlaceholder()

Gets the placeholder string of the time field.

Returns:

the placeholder property of the time picker

setStep

public void setStep(Duration step)

Sets the step property of the time picker using duration. It specifies the intervals for the displayed items in the time picker dropdown and also the displayed time format.

The set step needs to evenly divide a day or an hour and has to be larger than 0 milliseconds. By default, the format is hh:mm (same as * Duration.ofHours(1)

If the step is less than 60 seconds, the format will be changed to hh:mm:ss and it can be in hh:mm:ss.fff format, when the step is less than 1 second.

NOTE: If the step is less than 900 seconds, the dropdown is hidden.

NOTE: changing the step to a larger duration can cause a new HasValue.ValueChangeEvent to be fired if some parts (eg. seconds) is discarded from the value.

Parameters:

step - the step to set, not null and should divide a day or an hour evenly

getStep

public Duration getStep()

Gets the step of the time picker.

Returns:

the step property from the picker, unit seconds

setWeekNumbersVisible

public void setWeekNumbersVisible(boolean weekNumbersVisible)

Show or hide the week numbers in the date picker. By default the week numbers are not shown.

Set true to display ISO-8601 week numbers in the calendar.

Note that displaying of week numbers is only supported when i18n.firstDayOfWeek is 1 (Monday).

Parameters:

weekNumbersVisible - the boolean value to set

See Also:

#setDatePickerI18n(DatePickerI18n), DatePicker.DatePickerI18n.setFirstDayOfWeek(int)

isWeekNumbersVisible

public boolean isWeekNumbersVisible()

Get the state of showWeekNumbers property of the date picker.

Returns:

the showWeekNumbers property from the date picker

getDefaultValidator

public Validator<LocalDateTime> getDefaultValidator()

Description copied from interface: HasValidator

Returns a validator that checks the state of the Value. This should be overridden for components with internal value conversion or validation, e.g. when the user is providing a string that has to be parsed into a date. An invalid input from user will be exposed to a Binder and can be seen as a validation failure.

Specified by:

getDefaultValidator in interface HasValidator<LocalDateTime>

Returns:

state validator

addValidationStatusChangeListener

public Registration addValidationStatusChangeListener(ValidationStatusChangeListener<LocalDateTime> listener)

Description copied from interface: HasValidator

Enables the implementing components to notify changes in their validation status to the observers.

Note: This method can be overridden by the implementing classes e.g. components, to enable the associated Binder.Binding instance subscribing for their validation change events and revalidate itself.

This method primarily designed for notifying the Binding about the validation status changes of a bound component at the client-side. WebComponents such as <vaadin-date-picker> or any other component that accept a formatted text as input should be able to communicate their invalid status to their server-side instance, and a bound server-side component instance must notify its binding about this validation status change as well. When the binding instance revalidates, a chain of validators and convertors get executed one of which is the default validator provided by HasValidator.getDefaultValidator(). Thus, In order for the binding to be able to show/clear errors for its associated bound field, it is important that implementing components take that validation status into account while implementing any validator and converter including HasValidator.getDefaultValidator(). Here is an example:

 @Tag("date-picker-demo")
 public class DatePickerDemo implements HasValidator<LocalDate> {

     // Each web component has a way to communicate its validation status
     // to its server-side component instance. The following clientSideValid
     // state is introduced here just for the sake of simplicity of this code
     // snippet:
     boolean clientSideValid = true;

     /**
      * Note how clientSideValid engaged in the definition
      * of this method. It is important to reflect this status either
      * in the returning validation result of this method or any other
      * validation that is associated with this component.
      */
     @Override
     public Validator getDefaultValidator() {
          return (value, valueContext) -> clientSideValid ? ValidationResult.ok()
                 : ValidationResult.error("Invalid date format");
     }

     private final Collection<ValidationStatusChangeListener<LocalDate>>
         validationStatusListeners = new ArrayList<>();

     /**
      * This enables the binding to subscribe for the validation status
      * change events that are fired by this component and revalidate
      * itself respectively.
      */
     @Override
     public Registration addValidationStatusChangeListener(
             ValidationStatusChangeListener<LocalDate> listener) {
         validationStatusListeners.add(listener);
         return () -> validationStatusListeners.remove(listener);
     }

     private void fireValidationStatusChangeEvent(
             boolean newValidationStatus) {
         if (this.clientSideValid != newValidationStatus) {
             this.clientSideValid = newValidationStatus;
             var event = new ValidationStatusChangeEvent<>(this,
                     newValidationStatus);
             validationStatusListeners.forEach(
                     listener -> listener.validationStatusChanged(event));
         }
     }
 }
