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
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
登入窗口+小知识点
public class LoginDemo extends Application{ public static void main(String[] args) { launch(args); } @Override public void start(Stage stage) throws Exception { stage.setTitle("Login"); Label name =new Label("账号："); Label password = new Label("密码："); name.setFont(Font.font("宋体",20)); TextField inname =new TextField(); inname.setUserData("hello"); PasswordField inPasswordField =new PasswordField(); inPasswordField.setUserData("123456"); Button login =new Button("登录"); Button clear =new Button("清理"); GridPane gr =new GridPane(); gr.setStyle("-fx-background-color:#FFF5EE"); //列，行 gr.add(name, 0, 0); gr.add(inname, 1, 0); gr.add(password, 0, 1); gr.add(inPasswordField, 1, 1); gr.add(login, 1, 2); gr.add(clear, 0, 2); gr.setHgap(10); gr.setVgap(10); GridPane.setMargin(login, new Insets(0, 0, 0, 150)); gr.setAlignment(Pos.CENTER); //清理事件 clear.setOnAction(new EventHandler<ActionEvent>() { @Override public void handle(ActionEvent event) { inname.setText(""); inPasswordField.setText(""); } }); //登录事件 login.setOnAction((e)->{ String name1 =inname.getText(); String password1 =inPasswordField.getText(); if (inname.getUserData().equals(name1) && inPasswordField.getUserData().equals(password1)) { loginWindos lonWindos = new loginWindos(name1); stage.close(); }else { Alert waring = new Alert(Alert.AlertType.WARNING); waring.setHeaderText("用户名/密码出错"); waring.setContentText("请重新输入!"); //showAndWait（）;当输入的焦点在对话框里，后面的界面无法输入(不往下走，知道对话框关闭) waring.showAndWait(); //呼吸灯 FadeTransition fade = new FadeTransition(); fade.setDuration(javafx.util.Duration.seconds(2)); fade.setNode(gr); fade.setFromValue(0); fade.setToValue(1); fade.play(); } }); Scene scene =new Scene(gr); stage.setScene(scene); stage.setWidth(400); stage.setHeight(500); stage.setResizable(false); stage.show(); } class loginWindos { private final Stage stage = new Stage(); public loginWindos(String name) { stage.setTitle("qgs"); Alert waring = new Alert(Alert.AlertType.INFORMATION); waring.setHeaderText("欢迎"+name+"来到qgs操作界面"); waring.showAndWait(); stage.show(); } } }

jdk1.8以上的版本（jdk9，jdk11，jdk17等）没有jre的问题
D:\Program Files\Java\jdk-17目录下执行
