Class DatePicker

javafx.scene.control.DatePicker

All Implemented Interfaces:: Styleable, EventTarget, Skinnable

public class DatePicker extends ComboBoxBase<LocalDate>

The DatePicker control allows the user to enter a date as text or to select a date from a calendar popup. The calendar is based on either the standard ISO-8601 chronology or any of the other chronology classes defined in the java.time.chrono package.

The value property represents the currently selected LocalDate. An initial date can be set via the constructor or by calling setValue(LocalDate). The default value is null.

 DatePicker datePicker = new DatePicker();
 datePicker.setOnAction(e -> {
     LocalDate date = datePicker.getValue();
     System.err.println("Selected date: " + date);
 });

The chronology property specifies a calendar system to be used for parsing, displaying, and choosing dates. The value property is always defined in the ISO calendar system, however, so applications based on a different chronology may use the conversion methods provided in the Chronology API to get or set the corresponding ChronoLocalDate value. For example:

LocalDate isoDate = datePicker.getValue();
 ChronoLocalDate chronoDate =
     ((isoDate != null) ? datePicker.getChronology().date(isoDate) : null);
 System.err.println("Selected date: " + chronoDate);

Since:: JavaFX 8.0

Property Details

dayCellFactory

public final ObjectProperty<Callback<DatePicker,DateCell>> dayCellFactoryProperty

A custom cell factory can be provided to customize individual day cells in the DatePicker popup. Refer to DateCell and Cell for more information on cell factories. Example:


 final Callback<DatePicker, DateCell> dayCellFactory = new Callback<DatePicker, DateCell>() {
     public DateCell call(final DatePicker datePicker) {
         return new DateCell() {
             @Override public void updateItem(LocalDate item, boolean empty) {
                 super.updateItem(item, empty);

                 if (MonthDay.from(item).equals(MonthDay.of(9, 25))) {
                     setTooltip(new Tooltip("Happy Birthday!"));
                     setStyle("-fx-background-color: #ff4444;");
                 }
                 if (item.equals(LocalDate.now().plusDays(1))) {
                     // Tomorrow is too soon.
                     setDisable(true);
                 }
             }
         };
     }
 };
 datePicker.setDayCellFactory(dayCellFactory);

Default value:

null

See Also:

getDayCellFactory()
setDayCellFactory(Callback)
dayCellFactoryProperty()

chronology

public final ObjectProperty<Chronology> chronologyProperty

The calendar system used for parsing, displaying, and choosing dates in the DatePicker control.

The default value is returned from a call to Chronology.ofLocale(Locale.getDefault(Locale.Category.FORMAT)). The default is usually IsoChronology unless provided explicitly in the Locale by use of a Locale calendar extension. Setting the value to null will restore the default chronology.

See Also:

getChronology()
setChronology(Chronology)
chronologyProperty()

showWeekNumbers

public final BooleanProperty showWeekNumbersProperty

Whether the DatePicker popup should display a column showing week numbers.

The default value is specified in a resource bundle, and depends on the country of the current locale.

See Also:

isShowWeekNumbers()
setShowWeekNumbers(boolean)
showWeekNumbersProperty()

converter

public final ObjectProperty<StringConverter<LocalDate>> converterProperty

Converts the input text to an object of type LocalDate and vice versa.

If not set by the application, the DatePicker skin class will set a converter based on a DateTimeFormatter for the current Locale and chronology. This formatter is then used to parse and display the current date value. Setting the value to null will restore the default converter.

Example using an explicit formatter:


 datePicker.setConverter(new StringConverter<LocalDate>() {
     String pattern = "yyyy-MM-dd";
     DateTimeFormatter dateFormatter = DateTimeFormatter.ofPattern(pattern);

     {
         datePicker.setPromptText(pattern.toLowerCase());
     }

     @Override public String toString(LocalDate date) {
         if (date != null) {
             return dateFormatter.format(date);
         } else {
             return "";
         }
     }

     @Override public LocalDate fromString(String string) {
         if (string != null && !string.isEmpty()) {
             return LocalDate.parse(string, dateFormatter);
         } else {
             return null;
         }
     }
 });

Example that wraps the default formatter and catches parse exceptions:


   final StringConverter<LocalDate> defaultConverter = datePicker.getConverter();
   datePicker.setConverter(new StringConverter<LocalDate>() {
       @Override public String toString(LocalDate value) {
           return defaultConverter.toString(value);
       }

       @Override public LocalDate fromString(String text) {
           try {
               return defaultConverter.fromString(text);
           } catch (DateTimeParseException ex) {
               System.err.println("HelloDatePicker: "+ex.getMessage());
               throw ex;
           }
       }
   });

The default base year for parsing input containing only two digits for the year is 2000 (see DateTimeFormatter). This default is not useful for allowing a person's date of birth to be typed. The following example modifies the converter's fromString() method to allow a two digit year for birth dates up to 99 years in the past.


   @Override public LocalDate fromString(String text) {
       if (text != null && !text.isEmpty()) {
           Locale locale = Locale.getDefault(Locale.Category.FORMAT);
           Chronology chrono = datePicker.getChronology();
           String pattern =
               DateTimeFormatterBuilder.getLocalizedDateTimePattern(FormatStyle.SHORT,
                                                                    null, chrono, locale);
           String prePattern = pattern.substring(0, pattern.indexOf("y"));
           String postPattern = pattern.substring(pattern.lastIndexOf("y")+1);
           int baseYear = LocalDate.now().getYear() - 99;
           DateTimeFormatter df = new DateTimeFormatterBuilder()
                       .parseLenient()
                       .appendPattern(prePattern)
                       .appendValueReduced(ChronoField.YEAR, 2, 2, baseYear)
                       .appendPattern(postPattern)
                       .toFormatter();
           return LocalDate.from(chrono.date(df.parse(text)));
       } else {
           return null;
       }
   }
