被标记为已弃用。
反而使用什么?

这篇博客文章解释了这一切:
http://fxexperience.com/2014/09/announcing-controlsfx-8-20-7/
自从8.0.6于5月29日发布以来,这个版本一直在酝酿 - 所以基本上是四个月。这对我们来说并不典型(我们通常会有更快的版本发布),但Eugene和我都在一项重大工作中分心 - 将ControlsFX对话框API和实现提升到JavaFX本身的下一个版本中(它将出现在JavaFX 8u40中)虽然API与您在ControlsFX 8.0.6中看到的有很大不同。最终的结果是我们迭代了一堆API设计工作(参见RT-12643),但没有一个能使ControlsFX受益,但它占用了我们所有的时间。
一旦JavaFX 8u40对话框完成API(仅在8月中旬),我们就如何继续使用ControlsFX对话框制定了计划。从本质上讲,我们并不认为在ControlsFX中维护一个与JavaFX 8u40中提供的内容差别很大的对话API是明智的。因此,我们开发的计划是弃用旧的ControlsFX API,将JavaFX对话框API分成一个名为openjfx-dialogs的新项目,并使用新的API重新创建ControlsFX包含的其他功能(但在JavaFX本身中缺少)。 (这包括进度,字体选择器,命令链接,登录等对话框。)

现在使用java 8 update 60,即使使用旧的非弃用版本的controlsfx也不起作用。因此,解决方案是使用java 8 update 40中包含的javafx的本机对话框API(不需要第三方库)。它们不像控件fx那样直接且功能齐全。但是为了更快的编码,你可以创建一个包装类,就像我做的那样:

if (options == null || options.length == 0) {

}
List<ButtonType> buttons = new ArrayList<>();
for (String option : options) {

alert.getButtonTypes().setAll(buttons);

}

Optional<String> result = dialog.showAndWait();
if (result.isPresent()) {

}
使用对话框:
FxDialogs.showInformation("Hi", "Good Morning y'all!");
if (FxDialogs.showConfirm("Choose one baby!", "Can i ask you a question?", FxDialogs.YES, FxDialogs.NO).equals(FxDialogs.YES)) {
FxDialogs.showWarning(null, "Pay attention to my next question!");
String answer = FxDialogs.showTextInput("Are you a pink elephant disguised as a flying pig?", "Tell me!", "No");
FxDialogs.showError(null, "You should not have said " + answer + "!");
FxDialogs.showException("Now i'm angry", "I'm going home...", new RuntimeException("Exception caused by angry dinossaurs"));
}
