JavaFX 2.1 MessageBox [英] JavaFX 2.1 MessageBox

问题描述

美好的一天！

我正在使用JavaFX SDK开发一个程序。我希望有一个类似于C＃的消息框：

Good day!
I am developing a program using JavaFX SDK. I wanted to have a message box like in C#:

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

我希望使用JavaFX SDK获得这样的功能。答案非常感谢。

I want to have a functionality like this using JavaFX SDK. Answers are very much appreciated.

推荐答案

更新

从Java8u40开始，核心JavaFX库包括对话框（消息框）功能。请参阅以下类的文档：

As of Java8u40, the core JavaFX libraries include dialog (message box) functionality. Refer to the documentation for the following classes:

• 提醒


• 对话（和子类）

• Alert
• Dialog (and subclasses)

原始答案

以下是模态确认对话框。它的工作原理是创建一个包含场景的舞台，其中包含对话框内容，然后在场景上调用show（）。

Here is an example of a Modal Confirm dialog. It works by creating a Stage containing a Scene with the dialog contents in it, and then calling show() on the Scene.

如果你想让主处理线程暂停虽然显示了新舞台并且您正在使用JavaFX 2.2+，但您可以在舞台上调用showAndWait（）而不是显示。修改为使用show和wait，只显示一条消息和ok按钮，然后处理应该与C＃MessageBox非常相似。

If you want the main processing thread to pause whilst the new Stage is shown and you are using JavaFX 2.2+, then you can call showAndWait() on the Stage rather than show. Modified to use show and wait and just display a message and ok button, then processing should act quite similar to a C# MessageBox.

如果你想要一个专业的消息框Java 8，我建议使用 ControlsFX库中的对话框，这是JavaFX中对话框的后续迭代UI控件Sandbox在blo0p3r的答案中提到。

If you want a professional looking message box for Java 8, I recommend using the dialogs from the ControlsFX library, which is a later iteration of the dialogs in the JavaFX UI Controls Sandbox mentioned in blo0p3r's answer.
