在JDialog中使用JCalendar [英] Using JCalendar in a JDialog

问题描述

我的程序使用 JDialog 来打开表单，并以我想要的形式为用户使用 JCalendar 选择一个日期，然后我将其用于其他方法。

My program uses JDialogs to open up forms and in the form I want to use JCalendar for the user to select a date and for me to use it for other methods afterwards.

我已下载 JCalendar 库。我读了一些示例代码，但仍然不知道该怎么做。我有一个想法，你在表单中按下一个按钮（选择日期），就像一个小窗口打开那个 JCalendar ，当选择日期时，它会显示在表单中作为TextField。

I have downloaded JCalendar library. I read some example codes but still not sure how to do it. I have an idea that in the form you press a button (Select Date) and like a small window opens with that JCalendar and when the date is selected it is displayed in the form as a TextField.

有人可以推荐一些方法来解决这个问题吗？

Can someone recommend me some method of doing this with the least trouble?

您可能想尝试 JDateChooser 类存在于 JCalendar 库中，它允许选择日期或手动输入日期。关于第二部分，您需要提供 PropertyChangeListener 到日期选择器，以便监听日期属性更改并相应地更新文本字段的文本。例如：

You may want to try JDateChooser class present in JCalendar library, which allows selecting a date or type it manually. About the second part, you need to provide a PropertyChangeListener to the date chooser in order to listen the "date" property change and update the text field's text accordingly. For instance something like this:

final JTextField textField = new JTextField(15);

JDateChooser chooser = new JDateChooser();
chooser.setLocale(Locale.US);

chooser.addPropertyChangeListener("date", new PropertyChangeListener() {
    @Override
    public void propertyChange(PropertyChangeEvent evt) {
        JDateChooser chooser = (JDateChooser)evt.getSource();
        SimpleDateFormat formatter = new SimpleDateFormat("MM/dd/yyyy");
        textField.setText(formatter.format(chooser.getDate()));
    }
});

JPanel content = new JPanel();
content.add(chooser);
content.add(textField);

JDialog dialog = new JDialog ();
dialog.setDefaultCloseOperation(JDialog.DISPOSE_ON_CLOSE);
dialog.getContentPane().add(content);
dialog.pack();
dialog.setLocationRelativeTo(null);
dialog.setVisible(true);
