Java日期和日历控件

Question

是否有人对Java Swing应用程序中使用的日期选择器（下拉日历或小日历组件）有任何建议 - bean或源代码？他们需要足够强大的商业应用。

Answer 1

JCalendar是免费的，并提供豆类和源代码。它是相当可配置的，并且在我的应用程序中，迄今为止它的目的非常好。

Answer 2

尝试swinglabs。有很多比日期选择器...享受。

Answer 3

我同意Dan Dimerman，可以推荐swingX库。我们在商业应用中也使用JXDatePicker。与JXMonthView你有可能编写你自己的日期选择器的变体。

Answer 4

你可以使用这个只是改变了主您的需求^^
