How to change the text of yes/no buttons in JavaFX 8 Alert dialogs
提问by coderodde
I have this code snippet:
我有这个代码片段：
Alert alert =
new Alert(AlertType.WARNING,
"The format for dates is year.month.day. " +
"For example, today is " + todayToString() + ".",
ButtonType.OK,
ButtonType.CANCEL);
alert.setTitle("Date format warning");
Optional<ButtonType> result = alert.showAndWait();
if (result.get() == ButtonType.OK) {
formatGotIt = true;
}
Above, I request two buttons titled "Yes" and "No." However, I wish to change them both.
在上面，我请求了两个标题为“是”和“否”的按钮。但是，我想改变它们。

You can define your own button types. In this example the buttons' text is fooand bar:
您可以定义自己的按钮类型。在这个例子中，按钮的文本是foo和bar：
ButtonType foo = new ButtonType("foo", ButtonBar.ButtonData.OK_DONE);
ButtonType bar = new ButtonType("bar", ButtonBar.ButtonData.CANCEL_CLOSE);
Alert alert = new Alert(AlertType.WARNING,
"The format for dates is year.month.day. "
+ "For example, today is " + todayToString() + ".",
foo,
bar);
alert.setTitle("Date format warning");
Optional<ButtonType> result = alert.showAndWait();
if (result.orElse(bar) == foo) {
formatGotIt = true;
}

((Button) dialog.getDialogPane().lookupButton(ButtonType.OK)).setText("Not OK Anymore");
((Button) dialog.getDialogPane().lookupButton(ButtonType.CANCEL)).setText("Not Cancel Anymore");
