手拉手JavaFX UI控件与springboot3+FX桌面开发（中）：https://developer.aliyun.com/article/1431715

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;
    -fx-background-position: center center;*/
    /*-fx-effect: dropshadow(three-pass-box, black, 30, 0.5, 0, 0);*/
}
.root{
    -fx-background-image: url("中国风1.JPG");
}
Java文件
public class CSSdemo extends Application {
    TextField textField =new TextField();
    @Override
    public void start(Stage stage) throws Exception {
        stage.setTitle("CSSdemo");
        BorderPane borderPane = new BorderPane();
        HBox hbox =new HBox(10);
        Button b =new Button("选择");
        Button c =new Button("提交");
        textField.getStyleClass().add("text");
        b.getStyleClass().add("button");
        hbox.getChildren().addAll(textField,b,c);
       // borderPane.setId("pane");
        borderPane.setTop(hbox);
        Scene scene =new Scene(borderPane,300,400);
        //scene.getStylesheets().add(getClass().getResource("style.css").toExternalForm());
        //scene.getStylesheets().add(CSSdemo.class.getResource("style.css").toExternalForm());
        stage.setScene(scene);
        stage.show();
    }
    public static void main(String[] args) {
        launch();
    }
}

SceneBuilder可视化设计

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 {
   exports com;
   requires javafx.base;
   requires javafx.controls;
   requires javafx.fxml;
   requires javafx.graphics;
   requires javafx.media;
   requires javafx.swing;
   requires javafx.web;
   requires javafx-swt;
}

媒体播放器

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
