这是一个Java版本的DateTimePicker控件上面略有改进。

此代码现在是 TornadoFX Controls ，您可以查看最新版本的 DateTimePicker.java 。在这些坐标下，Maven Central中也可以使用该控件：

 < dependency> 
< groupId> no.tornado< / groupId> 
< artifactId> tornadofx-controls< / artifactId> 
< version> 1.0.3< / version> 
< / dependency> 
 

现在执行：

  import javafx.beans.property.ObjectProperty; 
 import javafx.beans.property.SimpleObjectProperty; 
 import javafx.scene.control.DatePicker; 
 import javafx.scene.input.KeyCode; 
 import javafx.scene.input.KeyEvent; 
 import javafx.util.StringConverter; 

 import java.time.LocalDate; 
 import java.time.LocalDateTime; 
 import java.time.LocalTime; 
 import java.time.format.DateTimeFormatter; 

 / ** 
 *具有可配置日期时间格式的DateTimePicker，可以通过文本字段更改日期和时间
 *，并且可以通过JavaFX默认值更改日期日期选择器
 * / 
 @SuppressWarnings（unused）
 public class DateTimePicker extends DatePicker {
 public static final String DefaultFormat =yyyy-MM-dd HH：mm; 

 private DateTimeFormatter formatter; 
 private ObjectProperty< LocalDateTime> dateTimeValue = new SimpleObjectProperty<>（LocalDateTime.now（））; 
 private ObjectProperty< String> format = new SimpleObjectProperty< String>（）{
 public void set（String newValue）{
 super.set（newValue）; 
 formatter = DateTimeFormatter.ofPattern（newValue）; 
} 
}; 

 public DateTimePicker（）{
 getStyleClass（）。add（datetime-picker）; 
 setFormat（DefaultFormat）; 
 setConverter（new InternalConverter（））; 

 //将基础日期值的更改同步到dateTimeValue 
 valueProperty（）。addListener（（observable，oldValue，newValue）） - > {
 if（newValue = = null）{
 dateTimeValue.set（null）; 
} else {
 if（dateTimeValue.get（）== null）{
 dateTimeValue.set（LocalDateTime.of（ newValue，LocalTime.now（）））; 
} else {
 LocalTime time = dateTimeValue.get（）。toLocalTime（）; 
 dateTimeValue.set（LocalDateTime.of（newValue，time） ）; 
} 
} 
}）; 

 //同步更改dateTimeValue回到基础日期值
 dateTimeValue.addListener（（observable，oldValue，newValue） - > {
 setValue（newValue == null？ null：newValue.toLocalDate（））; 
}）; 

 //持久变化onblur 
 getEditor（）。focusProperty（）。addListener（（observable，oldValue，newValue））> {
 if（！newValue）
 simulateEnterPressed（）; 
}）; 

} 

 private void simulateEnterPressed（）{
 getEditor（）。fireEvent（new KeyEvent（getEditor（），getEditor（），KeyEvent.KEY_PRESSED，null， null，KeyCode.ENTER，false，false，false，false））; 
} 

 public LocalDateTime getDateTimeValue（）{
 return dateTimeValue.get（）; 
} 

 public void setDateTimeValue（LocalDateTime dateTimeValue）{
 this.dateTimeValue.set（dateTimeValue）; 
} 

 public ObjectProperty< LocalDateTime> dateTimeValueProperty（）{
 return dateTimeValue; 
} 

 public String getFormat（）{
 return format.get（）; 
} 

 public ObjectProperty< String> formatProperty（）{
返回格式; 
} 

 public void setFormat（String format）{
 this.format.set（format）; 
} 

 class InternalConverter extends StringConverter< LocalDate> {
 public String toString（LocalDate object）{
 LocalDateTime value = getDateTimeValue（）; 
 return（value！= null）？ value.format（formatter）：; 
} 

 public LocalDate fromString（String value）{
 if（value == null）{
 dateTimeValue.set（null）; 
返回null; 
} 

 dateTimeValue.set（LocalDateTime.parse（value，formatter））; 
 return dateTimeValue.get（）。toLocalDate（）; 
} 
} 
} 
 

dateTimeValue 属性包含随时间的值，而 valueProperty 仅包含日期值。

我尚未添加此组件的测试，因此实施可能会更改，请检查GitHub的最新版本。

I am new to Java and I have started developing applications in java using javaFx. searched a lot but couldn't find any date and time picker in javaFx. Even i tried JFxtras but its not working. By the way i am using javafx 2.2.3 and java 7. Any help would be highly appreciated.

Here is a Java version of the DateTimePicker control above, slightly improved.

This code is now part of TornadoFX Controls and you can have a look at the latest version of DateTimePicker.java in the GitHub Repo. The control is available in Maven Central as well under these coordinates:

<dependency>
    <groupId>no.tornado</groupId>
    <artifactId>tornadofx-controls</artifactId>
    <version>1.0.3</version>
</dependency>

The implementation right now:

import javafx.beans.property.ObjectProperty;
import javafx.beans.property.SimpleObjectProperty;
import javafx.scene.control.DatePicker;
import javafx.scene.input.KeyCode;
import javafx.scene.input.KeyEvent;
import javafx.util.StringConverter;

import java.time.LocalDate;
import java.time.LocalDateTime;
import java.time.LocalTime;
import java.time.format.DateTimeFormatter;

/**
 * A DateTimePicker with configurable datetime format where both date and time can be changed
 * via the text field and the date can additionally be changed via the JavaFX default date picker.
 */
@SuppressWarnings("unused")
public class DateTimePicker extends DatePicker {
    public static final String DefaultFormat = "yyyy-MM-dd HH:mm";

    private DateTimeFormatter formatter;
    private ObjectProperty<LocalDateTime> dateTimeValue = new SimpleObjectProperty<>(LocalDateTime.now());
    private ObjectProperty<String> format = new SimpleObjectProperty<String>() {
        public void set(String newValue) {
            super.set(newValue);
            formatter = DateTimeFormatter.ofPattern(newValue);
        }
    };

    public DateTimePicker() {
        getStyleClass().add("datetime-picker");
        setFormat(DefaultFormat);
        setConverter(new InternalConverter());

        // Syncronize changes to the underlying date value back to the dateTimeValue
        valueProperty().addListener((observable, oldValue, newValue) -> {
            if (newValue == null) {
                dateTimeValue.set(null);
            } else {
                if (dateTimeValue.get() == null) {
                    dateTimeValue.set(LocalDateTime.of(newValue, LocalTime.now()));
                } else {
                    LocalTime time = dateTimeValue.get().toLocalTime();
                    dateTimeValue.set(LocalDateTime.of(newValue, time));
                }
            }
        });

        // Syncronize changes to dateTimeValue back to the underlying date value
        dateTimeValue.addListener((observable, oldValue, newValue) -> {
            setValue(newValue == null ? null : newValue.toLocalDate());
        });

        // Persist changes onblur
        getEditor().focusedProperty().addListener((observable, oldValue, newValue) -> {
            if (!newValue)
                simulateEnterPressed();
        });

    }

    private void simulateEnterPressed() {
        getEditor().fireEvent(new KeyEvent(getEditor(), getEditor(), KeyEvent.KEY_PRESSED, null, null, KeyCode.ENTER, false, false, false, false));
    }

    public LocalDateTime getDateTimeValue() {
        return dateTimeValue.get();
    }

    public void setDateTimeValue(LocalDateTime dateTimeValue) {
        this.dateTimeValue.set(dateTimeValue);
    }

    public ObjectProperty<LocalDateTime> dateTimeValueProperty() {
        return dateTimeValue;
    }

    public String getFormat() {
        return format.get();
    }

    public ObjectProperty<String> formatProperty() {
        return format;
    }

    public void setFormat(String format) {
        this.format.set(format);
    }

    class InternalConverter extends StringConverter<LocalDate> {
        public String toString(LocalDate object) {
            LocalDateTime value = getDateTimeValue();
            return (value != null) ? value.format(formatter) : "";
        }

        public LocalDate fromString(String value) {
            if (value == null) {
                dateTimeValue.set(null);
                return null;
            }

            dateTimeValue.set(LocalDateTime.parse(value, formatter));
            return dateTimeValue.get().toLocalDate();
        }
    }
}

The dateTimeValue property contains the value with time, and the valueProperty contains only the date value.

I have not added tests for this component yet, so the implementation might change, check GitHub for the latest version.
