Java Swing JXDatePicker

我正在使用SwingX JXDatePicker，我无法弄清楚如何提供下一个/上一年的按钮（默认情况下它只提供下一个/上个月的按钮）。

此外，似乎不再维护SwingX：我应该使用更新的组件作为日期选择器吗？

任何帮助/提示将不胜感激。 谢谢，托马斯

更新：

为了澄清这个问题，我添加了一个JXDatePicker截图，并以红色突出显示下一个/上个月的按钮。 问题是：如何添加将日历带到下一年/上一年的按钮？ 请注意，新按钮需要是标准组件，因为它们需要由特定的Look＆Feel管理器（在本例中为Insusbtantial）呈现。

非常感谢

Answer 1

我建议使用Microba DatePicker。 它是高度可定制的，完全符合您的要求。

http://microba.sourceforge.net/

编辑：

好的我明白了。 好吧，我做了一些研究，看起来你正在寻找的function实际上并不存在于JXDatePicker中。

我找到的另一种选择是： http ：//sourceforge.net/projects/jdatepicker/上的JDatePicker。

主要网站： https ： //jdatepicker.org/

这仍然受支持，似乎有你想要的function。

我知道这是一个老问题，但我终于找到了答案，来自kleopatra关于SwingsLab演示的评论。

SwingsLab演示提供了一个如何基于每个组件设置自定义日历标题的示例，但这是我实际使用的代码（这是全局的;每个应用程序）：

UIManager.put(CalendarHeaderHandler.uiControllerID, SpinningCalendarHeaderHandler.class.getName()); datePicker = new JXDatePicker(); datePicker.getMonthView().setZoomable(true); //this is needed for custom header 

这似乎是实验性代码（尚未完全公开），因此使用风险自负。 希望能帮助到你。

这是几年前我把它放在一起的东西。 您可以对其进行修改以满足您的需求。

您需要此图像才能运行主测试： 。 只需将其放在与源名称为datepicker.gif的目录相同的目录中即可。

改进：

datetimePicker离按钮太远了

在第139行：

 public Popup getPopup(Container c) { if (popup == null) { Point p = c.getLocation(); PopupFactory factory = PopupFactory.getSharedInstance(); // FramePrinc.Location.x ==> public static Point Location ; in class FramePrinc popup = factory.getPopup(c, this, FramePrinc.Location.x,FramePrinc.Location.y); } return popup; } 

在操作中，您将获得组件的位置

 datePicker.addActionListener(new ActionListener() { public void actionPerformed(ActionEvent e) { //Add this Line and you will get a good result Location = datePickerButton.getLocationOnScreen(); dp.setDate(testDate.getText()); dp.popupShow(datePicker); } }); 

所以：

• 创建另一个类：例如FramePrinc
• 创建公共静态点位置
• 在面板中添加dateTimePiker
• 把我所说的线放在按钮动作中

祝好运

Answer 5

JXDatePicker中缺少内置的上一个/下一个按钮是我最终没有使用该软件包的主要原因。 否则，它是最好的日期选择器之一。

作为替代方案，我推荐LGoodDatePicker 。 它有按钮，用于在年份中前后移动，以及用于选择任何所需年份的菜单。 公平披露：我是这个项目的主要开发人员。 如果满足您的需求，请告诉我。

LGoodDatePicker主页： https ： //github.com/LGoodDatePicker/LGoodDatePicker

发布部分中有一个工作演示（可执行jar文件），以及gitub页面上的核心function列表。

屏幕截图如下。
