Method Details
-
setLabel
Sets the label for the time picker. -
setValue
Sets the selected 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 interfaceHasValue<AbstractField.ComponentValueChangeEvent<TimePicker,
LocalTime>, LocalTime> - Overrides:
setValue
in classAbstractField<TimePicker,
LocalTime> - Parameters:
value
- the LocalTime instance representing the selected time, or null
-
getLabel
Gets the label of the time picker. -
setAriaLabel
Description copied from interface:HasAriaLabel
Set the aria-label of the component to the given text.This method should not be used if
HasAriaLabel.setAriaLabelledBy(String)
is also used. If both attributes are present, aria-labelledby will take precedence over aria-label.- Specified by:
setAriaLabel
in interfaceHasAriaLabel
- Parameters:
ariaLabel
- the aria-label text to set ornull
to clear
-
getAriaLabel
Description copied from interface:HasAriaLabel
Gets the aria-label of the component.- Specified by:
getAriaLabel
in interfaceHasAriaLabel
- Returns:
- an optional aria-label of the component if no aria-label has been set
-
setAriaLabelledBy
Description copied from interface:HasAriaLabel
Set the aria-labelledby of the component. The value must be a valid id attribute of another element that labels the component. The label element must be in the same DOM scope of the component, otherwise screen readers may fail to announce the label content properly.This method should not be used if
HasAriaLabel.setAriaLabel(String)
is also used. If both attributes are present, aria-labelledby will take precedence over aria-label.- Specified by:
setAriaLabelledBy
in interfaceHasAriaLabel
- Parameters:
labelledBy
- the string with the id of the element that will be used as label ornull
to clear
-
getAriaLabelledBy
Description copied from interface:HasAriaLabel
Gets the aria-labelledby of the component- Specified by:
getAriaLabelledBy
in interfaceHasAriaLabel
- Returns:
- an optional aria-labelledby of the component if no aria-labelledby has been set
-
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 aBinder
and can be seen as a validation failure.- Specified by:
getDefaultValidator
in interfaceHasValidator<LocalTime>
- Returns:
- state validator
-
addValidationStatusChangeListener
public Registration addValidationStatusChangeListener(ValidationStatusChangeListener<LocalTime> 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 byHasValidator.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 includingHasValidator.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)); } } }- Specified by:
addValidationStatusChangeListener
in interfaceHasValidator<LocalTime>
- Returns:
- Registration of the added listener.
- See Also:
-
isInputValuePresent
@Synchronize(property="_hasInputValue", value="has-input-value-changed") protected boolean isInputValuePresent()Returns whether the input element has a value or not.- Returns:
true
if the input element's value is populated,false
otherwise
-
setRequired
public void setRequired(boolean required) Sets whether the time picker is marked as input required.- Parameters:
required
- the boolean value to set
-
setRequiredIndicatorVisible
public void setRequiredIndicatorVisible(boolean requiredIndicatorVisible) 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 whensetRequiredIndicatorVisible(true)
is called and re-enabled back onsetRequiredIndicatorVisible(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 ownsetRequired
method which should be called in case the client-side validation is required.- Specified by:
setRequiredIndicatorVisible
in interfaceHasValue<AbstractField.ComponentValueChangeEvent<TimePicker,
LocalTime>, LocalTime> - Specified by:
setRequiredIndicatorVisible
in interfaceHasValueAndElement<AbstractField.ComponentValueChangeEvent<TimePicker,
LocalTime>, LocalTime> - Parameters:
requiredIndicatorVisible
-true
to make the required indicator visible,false
if not
-
isRequired
public boolean isRequired()Determines whether the time picker 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
-
setStep
Sets thestep
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 inhh: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, notnull
and should divide a day or an hour evenly
-
getStep
Gets the step of the time picker.This property is not synchronized automatically from the client side, so the returned value may not be the same as in client side.
- Returns:
- the
step
property from the picker, unit seconds
-
addInvalidChangeListener
public Registration addInvalidChangeListener(ComponentEventListener<TimePicker.InvalidChangeEvent> listener) Adds a listener forinvalid-changed
events fired by the webcomponent.- Parameters:
listener
- the listener- Returns:
- a
Registration
for removing the event listener
-
setManualValidation
public void setManualValidation(boolean enabled) Description copied from interface:HasValidation
Sets whether manual validation mode is enabled for the component.When enabled, the component doesn't perform its built-in constraint validation on value change, blur, and other events. This allows manually controlling the invalid state and error messages using the
HasValidation.setInvalid(boolean)
andHasValidation.setErrorMessage(String)
methods. Manual mode is helpful when there is a need for a totally custom validation logic that cannot be achieved with Binder.Example:
Field field = new Field(); field.setManualValidation(true); field.addValueChangeListener(event -> { if (Objects.equal(event.getValue(), "")) { field.setInvalid(true); field.setErrorMessage("The field is required."); } else { field.setInvalid(false); } });
For components that don't have built-in validation, the method has no effect.
- Specified by:
setManualValidation
in interfaceHasValidation
- Parameters:
enabled
- whether to enable manual validation mode.
-
validate
protected void validate()Performs server-side validation of the current value. This is needed because it is possible to circumvent the client-side validation constraints using browser development tools. -
onAttach
Description copied from class:Component
Called when the component is attached to a UI.This method is invoked before the
Make sure to callAttachEvent
is fired for the component.super.onAttach
when overriding this method. -
setLocale
Set the Locale for the Time Picker. The displayed time will be formatted by the browser using the given locale.By default, the locale is
null
until the component is attached to an UI, and then locale is set toUI.getLocale()
, unless a locale has been explicitly set before that.The time formatting is done in the browser using the Date.toLocaleTimeString() function.
If for some reason the browser doesn't support the given locale, the en-US locale is used.
NOTE: only the language + country/region codes are used. This means that the script and variant information is not used and supported. NOTE: timezone related data is not supported. NOTE: changing the locale does not cause a new
HasValue.ValueChangeEvent
to be fired.- Parameters:
locale
- the locale set to the time picker, cannot be [@code null}
-
getLocale
Gets the Locale for this time picker.By default, the locale is
null
until the component is attached to an UI, and then locale is set toUI.getLocale()
, unlesssetLocale(Locale)
has been explicitly called before that. -
setMin
Sets the minimum time in the time picker. Times before that will be disabled in the popup.- Parameters:
min
- the minimum time that is allowed to be selected, ornull
to remove any minimum constraints
-
getMin
Gets the minimum time in the time picker. Time before that will be disabled in the popup.- Returns:
- the minimum time that is allowed to be selected, or
null
if there's no minimum
-
setMax
Sets the maximum time in the time picker. Times after that will be disabled in the popup.- Parameters:
max
- the maximum time that is allowed to be selected, ornull
to remove any maximum constraints
-
getMax
Gets the maximum time in the time picker. Times after that will be disabled in the popup.- Returns:
- the maximum time that is allowed to be selected, or
null
if there's no maximum
-
getSupportedAvailableLocales
Returns a stream of all the available locales that are supported by the time picker component.This is a shorthand for
Locale.getAvailableLocales()
where all locales without theLocale.getLanguage()
have been filtered out, as the browser cannot localize the time for those.- Returns:
- a stream of the available locales that are supported by the time picker component
