}FileChooser文件选择器
打开文件
文件选择器可用作打开文件对话框，用于选择单个文件或多个文件，或作为文件保存对话框。以下代码创建一个FileChooser对象并设置其标题，然后显示给用户。
FileChooser fileChooser = new FileChooser();
fileChooser.setTitle("Open Resource File");
fileChooser.showOpenDialog(stage);
可以通过设置initialDirectory和title属性来配置文件选择器对话框窗口。
扩展过滤器
可以设置扩展过滤器来确定在文件选择器中打开哪些文件。
fileChooser.setTitle("View Pictures");
fileChooser.setInitialDirectory(new File(System.getProperty("user.home"))
);
fileChooser.getExtensionFilters().addAll(
new FileChooser.ExtensionFilter("All Images", "*.*"),
new FileChooser.ExtensionFilter("JPG", "*.jpg"),
new FileChooser.ExtensionFilter("GIF", "*.gif"),
new FileChooser.ExtensionFilter("BMP", "*.bmp"),
new FileChooser.ExtensionFilter("PNG", "*.png")
);保存文件
FileChooser API允许用户为由应用程序保存的文件指定文件名及其文件夹。
showSaveDialog方法打开保存对话框窗口。
FileChooser fileChooser1 = new FileChooser();
fileChooser1.setTitle("Save Image");
System.out.println(pic.getId());
File file = fileChooser1.showSaveDialog(stage);
System.out.println(file);案例：

}
颜色定义
RGB / YVU / HSB
RGB方式是最常见的方式
(255,0,0)红色、(0,0,0)黑色
绘制文字
stroskText()绘制线条
fillText填充
gc.setFont(new Font("微软雅黑",40));
gc.fillText("hello world",200,200);
//文字基线(顶部对齐)
gc.setTextBaseline(VPos.TOP);
//水平方向对齐
gc.setTextAlign(TextAlignment.CENTER);
gc.fillOval(0,0,200,200);//椭圆drawImage绘制图片
drawImage(Image img,double sx,double sy,double sw,double sh,double dx,double dy,double dw,double dh)
img:要绘制的图片
sx,sy,sw,sh:源矩形(s,source)
dx,dy,sw,dh:目标矩形(d,destination)
样式单CSS
CSS,Cascading Style Sheets
用于定义界面的显示样式(背景，边框，字体等)
-fx-padding:填充、-fx-font-size：字体大小、-fx-text-fill：文件颜色
新建javafx项目时，已经默认创建了一个CSS文件：application.css
图片背景
CSS文件
#pane{
-fx-background-image: url("中国风1.JPG");
/*-fx-background-repeat: stretch;
-fx-background-size: 900 506;

Eclipse添加javafx组件
在Work with中添加：http://download.eclipse.org/efxclipse/updates-released/2.3.0/site/
Eclpise-jdk11-javaFx
https://openjfx.cn/
module Java11 {

Javafx自带媒体播放的支持
Media：表示一个媒体文件(URL)
MediaPlayer:表示一个播放器(播放控件)
MediaView:表示一个播放控件(显示)
Eclpise应用程序的发布
创建一个文件夹，将jdk里的jre拷贝过去
创建启动脚本
IEDA 应用程序的发布
右击项目或模块
open module settings
选择ArtiFacts->JAR->From modules with dependencies
可以选择包含测试类或者不包含
第一个仅导出目标jar包
第二个导出目标jar包和项目所依赖的jar包
选择Include in project build
Build -> Build Artifacts -> Build
构建结果如下：
创建一个文件夹，将jdk里的jre拷贝过去
创建启动脚本
start jre\bin\javaw.exe -jar ch01.jar
