有可用于 Java Swing 的好的免费日期和时间选择器吗？ [关闭]

Question

有没有可用于 Java Swing 的好的免费日期和时间选择器？

有很多可用的日期选择器，但没有日期和时间选择器。这是迄今为止我遇到的最接近的：Looking for a date AND time picker

有人吗？

Answer 1

对于时间选择器，您可以使用 JSpinner 并设置仅显示时间值的 JSpinner.DateEditor。

JSpinner timeSpinner = new JSpinner( new SpinnerDateModel() );
JSpinner.DateEditor timeEditor = new JSpinner.DateEditor(timeSpinner, "HH:mm:ss");
timeSpinner.setEditor(timeEditor);
timeSpinner.setValue(new Date()); // will only show the current time

Answer 2

您可以扩展 swingx JXDatePicker 组件：

“JXDatePicker 只处理没有时间的日期。很多时候我们需要让用户选择日期和时间。这是一个如何使用 JXDatePicker 一起处理日期和时间的示例。”

编辑：这篇文章从网络上消失了，但正如 SingleShot 发现的那样，它仍然可以在互联网档案中找到。可以肯定的是，这里是完整的工作示例：

import org.jdesktop.swingx.calendar.SingleDaySelectionModel;
import org.jdesktop.swingx.JXDatePicker;

import javax.swing.*;
import javax.swing.text.DefaultFormatterFactory;
import javax.swing.text.DateFormatter;
import java.text.DateFormat;
import java.text.ParseException;
import java.util.*;
import java.awt.*;

public class DateTimePicker extends JXDatePicker {
    private JSpinner timeSpinner;
    private JPanel timePanel;
    private DateFormat timeFormat;

    public DateTimePicker() {
        super();
        getMonthView().setSelectionModel(new SingleDaySelectionModel());
    }

    public DateTimePicker( Date d ) {
        this();
        setDate(d);
    }

    public void commitEdit() throws ParseException {
        commitTime();
        super.commitEdit();
    }

    public void cancelEdit() {
        super.cancelEdit();
        setTimeSpinners();
    }

    @Override
    public JPanel getLinkPanel() {
        super.getLinkPanel();
        if( timePanel == null ) {
            timePanel = createTimePanel();
        }
        setTimeSpinners();
        return timePanel;
    }

    private JPanel createTimePanel() {
        JPanel newPanel = new JPanel();
        newPanel.setLayout(new FlowLayout());
        //newPanel.add(panelOriginal);

        SpinnerDateModel dateModel = new SpinnerDateModel();
        timeSpinner = new JSpinner(dateModel);
        if( timeFormat == null ) timeFormat = DateFormat.getTimeInstance( DateFormat.SHORT );
        updateTextFieldFormat();
        newPanel.add(new JLabel( "Time:" ) );
        newPanel.add(timeSpinner);
        newPanel.setBackground(Color.WHITE);
        return newPanel;
    }

    private void updateTextFieldFormat() {
        if( timeSpinner == null ) return;
        JFormattedTextField tf = ((JSpinner.DefaultEditor) timeSpinner.getEditor()).getTextField();
        DefaultFormatterFactory factory = (DefaultFormatterFactory) tf.getFormatterFactory();
        DateFormatter formatter = (DateFormatter) factory.getDefaultFormatter();
        // Change the date format to only show the hours
        formatter.setFormat( timeFormat );
    }

    private void commitTime() {
        Date date = getDate();
        if (date != null) {
            Date time = (Date) timeSpinner.getValue();
            GregorianCalendar timeCalendar = new GregorianCalendar();
            timeCalendar.setTime( time );

            GregorianCalendar calendar = new GregorianCalendar();
            calendar.setTime(date);
            calendar.set(Calendar.HOUR_OF_DAY, timeCalendar.get( Calendar.HOUR_OF_DAY ) );
            calendar.set(Calendar.MINUTE, timeCalendar.get( Calendar.MINUTE ) );
            calendar.set(Calendar.SECOND, 0);
            calendar.set(Calendar.MILLISECOND, 0);

            Date newDate = calendar.getTime();
            setDate(newDate);
        }

    }

    private void setTimeSpinners() {
        Date date = getDate();
        if (date != null) {
            timeSpinner.setValue( date );
        }
    }

    public DateFormat getTimeFormat() {
        return timeFormat;
    }

    public void setTimeFormat(DateFormat timeFormat) {
        this.timeFormat = timeFormat;
        updateTextFieldFormat();
    }

    public static void main(String[] args) {
        Date date = new Date();
        JFrame frame = new JFrame();
        frame.setTitle("Date Time Picker");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        DateTimePicker dateTimePicker = new DateTimePicker();
        dateTimePicker.setFormats( DateFormat.getDateTimeInstance( DateFormat.SHORT, DateFormat.MEDIUM ) );
        dateTimePicker.setTimeFormat( DateFormat.getTimeInstance( DateFormat.MEDIUM ) );

        dateTimePicker.setDate(date);

        frame.getContentPane().add(dateTimePicker);
        frame.pack();
        frame.setVisible(true);
    }
}

Answer 3

使用两者结合..这就是我所做的：

public static JPanel buildDatePanel(String label, Date value) {
JPanel datePanel = new JPanel();

JDateChooser dateChooser = new JDateChooser();
if (value != null) {
    dateChooser.setDate(value);
}
for (Component comp : dateChooser.getComponents()) {
    if (comp instanceof JTextField) {
    ((JTextField) comp).setColumns(50);
    ((JTextField) comp).setEditable(false);
    }
}

datePanel.add(dateChooser);

SpinnerModel model = new SpinnerDateModel();
JSpinner timeSpinner = new JSpinner(model);
JComponent editor = new JSpinner.DateEditor(timeSpinner, "HH:mm:ss");
timeSpinner.setEditor(editor);
if(value != null) {
    timeSpinner.setValue(value);
}

datePanel.add(timeSpinner);

return datePanel;
}

Answer 4

FLib-JCalendar 组件具有组合的日期和时间选择器。

Answer 5

正如你所说的日期选择器很容易，那里有很多。

至于时间选择器，请查看 Google 日历在创建新条目时是如何做到的。它允许您输入任何内容，同时它以 30 分钟为增量提供下拉菜单。当您更改分钟时，下拉菜单会发生变化。

如果您需要允许用户选择秒数，那么您能做的最好的就是键入/下拉组合
