JavaFX 2.1 消息框

Question

美好的一天!
我正在使用 JavaFX SDK 开发程序。我想要像 C# 中那样的消息框:

DialogResult rs = MessageBox.showDialog("Message Here...");
if (rs == ....) {
    // code
}

我想使用 JavaFX SDK 实现这样的功能。非常感谢您的回答。

https://docs.oracle.com/javase/8/javafx/api/javafx/scene/control/Alert.html

The Alert class subclasses the Dialog class, and provides support for a number of pre-built dialog types that can be easily shown to users to prompt for a response.

所以代码看起来像

Alert alert = new Alert(AlertType.INFORMATION);
alert.setTitle("Message Here...");
alert.setHeaderText("Look, an Information Dialog");
alert.setContentText("I have a great message for you!");
alert.showAndWait().ifPresent(rs -> {
    if (rs == ButtonType.OK) {
        System.out.println("Pressed OK.");
    }
});
