ChoiceDialog

ChoiceDialog 允许用户从选项列表中选择一个项目。

List<String> options = new ArrayList<>();
options.add("42");
options.add("9");
options.add("467829");
options.add("Other");

ChoiceDialog<String> dialog = new ChoiceDialog<>(options.get(0), options);
dialog.setHeaderText("Choose your favourite number.");
dialog.setTitle("Favourite number?");
dialog.setContentText("Your favourite number:");

Optional<String> choice = dialog.showAndWait();

String s = choice.map(c -> "Other".equals(c) ? 
              "Unfortunately your favourite number is not available!"
              : "Nice! I like " + c + " too!")
           .orElse("You really don't want to tell me, huh?");

System.out.println(s);
