Does anyone have any idea why JavaFX 8 still isn't an everyday J2SE API in the upcoming Java 8?
 
The technology diagram showing all the Java components clearly excludes JavaFX from the J2SE stack.
 
I'd like to see JavaFX and Swing APIs side-by-side in the JDK javadocs.. and wonder why Oracle doesn't/can't give us that?
 
BTW, on the topic of JavaFX's different status (compared to other standards included in the J2SE), can anyone explain why the authors of JavaFX felt it absolutely necessary to re-invent the wheel creating AWT/Swing-incompatible concepts like FX Fonts, FX Colors, and the like?
 
解决方案
 
According to the FAQ-
 
As of JavaFX 2.2 and Java SE 7 update 6, the JavaFX libraries are
 
installed as part of Java SE;
 
For the swing part-
 
Is JavaFX replacing Swing as the new client UI library for Java SE?
 
Yes. However, Swing will remain part of the Java SE specification for
 
the foreseeable future, and therefore included in the JRE.
 
JavaFX is broad enough to have a separate hierarchy just like Java SE or Java EE.
 
You can see the definition here.
 
Java SE
 
When most people think of the Java programming language, they think of
 
the Java SE API. Java SE's API provides the core functionality of the
 
Java programming language. It defines everything from the basic types
 
and objects of the Java programming language to high-level classes
 
that are used for networking, security, database access, graphical
 
user interface (GUI) development, and XML parsing.
 
Java EE
 
The Java EE platform is built on top of the Java SE platform. The Java
 
EE platform provides an API and runtime environment for developing and
 
running large-scale, multi-tiered, scalable, reliable, and secure
 
network applications.
 
Java ME
 
The Java ME platform provides an API and a small-footprint virtual
 
machine for running Java programming language applications on small
 
devices, like mobile phones. The API is a subset of the Java SE API,
 
along with special class libraries useful for small device application
 
development. Java ME applications are often clients of Java EE
 
platform services.
 
JavaFX
 
JavaFX is a platform for creating rich internet applications using a
 
lightweight user-interface API. JavaFX applications use
 
hardware-accelerated graphics and media engines to take advantage of
 
higher-performance clients and a modern look-and-feel as well as
 
high-level APIs for connecting to networked data sources. JavaFX
 
applications may be clients of Java EE platform services.

 
Windows上面直接使用Maven的依赖就可以直接运行，但是Linux上面却不行。
 
配置环境变量：
 
export JAVAFX=/home/javafx-sdk-11.0.2/lib
 
运行启动命令：
 
java --module-path $JAVAFX --add-modules javafx.fxml,javafx.controls -jar snail.jar
 
后来我发现了一个更好的解决方案，就是pom.xml的配置也可以解决。
 
在Window上面只需要配置fxml/controls就可以了，其他的会自动引入：
 
org.openjfx
 
javafx-fxml
 
${javafx.version}
 
${os.name}
 
org.openjfx
 
javafx-controls
 
${javafx.version}
 
${os.name}
 
Linux打包时把其他的都显示声明就可以了：
 
org.openjfx
 
javafx-fxml
 
${javafx.version}
 
${os.name}
 
org.openjfx
 
javafx-controls
 
${javafx.version}
 
${os.name}
 
org.openjfx
 
javafx-base
 
${javafx.version}
 
${os.name}
 
org.openjfx
 
javafx-graphics
 
${javafx.version}
 
${os.name}
 
其实这个问题主要是我在Win上面打包的问题，默认使用的是打包系统的软件版本。
 
也可以直接使用Maven命令指定系统：
 
mvn clean package -DskipTests "-Djavafx.platform=linux"

用javafx写一个小工具，使用dialog弹出窗口时碰到不能关闭的情况,
 
 
查了下 文档，文档 这样说的，
 
如果需要按上图中所未关闭窗口，必须
要么添加至少一个按钮，要么添加多个按钮，其中一个按钮的类型ButtonData.CANCEL_CLOSE
 
--------------------------------直接看对应代码------------------------------
 1、至少一个按钮
 
Dialog<ButtonType> dialog = new Dialog<>();
dialog.getDialogPane().getButtonTypes().add(new ButtonType("确认", ButtonBar.ButtonData.OK_DONE));
dialog.setTitle("测试");
dialog.showAndWait();
 
2、多个按钮但其中一个类型为ButtonData.CANCEL_CLOSE
 
Dialog dialog = new Dialog();
dialog.getDialogPane().getButtonTypes().add(ButtonType.CLOSE);
dialog.getDialogPane().getButtonTypes().add(new ButtonType("测试按钮1"));
dialog.getDialogPane().getButtonTypes().add(new ButtonType("测试按钮2"));
dialog.setTitle("测试");
dialog.showAndWait();
 
----------------------------反例，这种关闭按钮无效-----------------------------------------------
 
Dialog dialog = new Dialog();
//        dialog.getDialogPane().getButtonTypes().add(ButtonType.CLOSE);
dialog.getDialogPane().getButtonTypes().add(new ButtonType("测试按钮1"));
dialog.getDialogPane().getButtonTypes().add(new ButtonType("测试按钮2"));
dialog.setTitle("测试");
dialog.showAndWait();
 
挺奇怪为啥要这样设计-- 应该就这些了-

JavaFX教程-什么是JavaFX?
 
 
 
1.JavaFX是基于java语言的 图形化界面工具箱，带有大量的内置组件,如按钮，文本字段，表格，树，菜单，图表等
 
 
 
 
2.JavaFX支持 2D图形、3D图形、WebView
 
 
 
 
3.JavaFX编写的程序，可以运行在 Windows、Linux、Mac、iOS、Android / Chromebook、树莓派
 
 
 
 
4.JavaFX让使用Java语言 创建桌面应用程序 和 游戏（https://github.com/AlmasB/FXGL）变得更加容易
 
 
 
 
5.从Java 11开始，JavaFX已从Java SDK中删除。JavaFX已被分离到其自己的开源项目中。想要使用需要额外引用依赖包。
