FlowPane布局

Flowpane是一个容器。它在一行上排列连续的子组件，并且如果当前行填充满了以后，则自动将子组件向下推到一行

public class FlowPanedemo extends Application {

    @Override

    public void start(Stage stage) throws Exception {

        stage.setTitle("FlowPanedemo");

        FlowPane flowPane = new FlowPane();

        //设置控件的垂直水平间距

        flowPane.setHgap(10);

        flowPane.setVgap(10);

        Button button1 = new Button("button1");

        Button button2 = new Button("button2");

        button2.setPrefSize(100,100);

        Text text = new Text();

        text.setText("hello world");

        text.setFill(Color.RED);

        //复选框

        CheckBox checkBox = new CheckBox();

        checkBox.setText("123");

        RadioButton radioButton = new RadioButton();

        radioButton.setText("radiobuttion");

        TextField textField = new TextField();

        textField.setText("111");

        flowPane.getChildren().addAll(button1,button2,text,checkBox,radioButton,textField);

        Scene scene = new Scene(flowPane,500,300);

        stage.setScene(scene);

        stage.show();

    }

    public static void main(String[] args) {

        launch();

    }

}

    @Override

    public void start(Stage stage) throws Exception {

        stage.setTitle("HBoxDemo");

        Group group = new Group();

            //创建水平布局

        HBox hbox = new HBox();

        //配置背后颜色

        hbox.setStyle("-fx-background-color: #336699;");

        hbox.setMinWidth(300);

        hbox.setMinHeight(50);

        group.getChildren().add(hbox);

        //设置控件间的间距

        hbox.setSpacing(10);

        Button button = new Button();

        button.setText("确定");

        Text text = new Text();

        text.setText("hello");

        text.setFont(Font.font("宋体",30));

        //Insets:设置偏移量 上右下左

        hbox.setMargin(button,new Insets(10,0,0,0));

    }

}

VBox垂直布局

Rectangle矩形、Label标签、TextArea文本域（输入框）、Alignment对齐

public void start(Stage stage) throws Exception {

        stage.setTitle("VBoxdemo");

        Group group = new Group();

        TextArea mytestArea =new TextArea();

        HBox hbox = new HBox(50);

        hbox.setMinWidth(600);

        hbox.setMinHeight(100);

        hbox.setStyle("-fx-background-color: #336699;");

        Rectangle r1 = new Rectangle(200,200);

        r1.setY(300);

        r1.setX(300);

        Label lbl =new Label("VBox");

        group.getChildren().addAll(hbox,vbox,r1);

        Scene scene =new Scene(group,600,500, Color.rgb(0,0,0,0));

        stage.setScene(scene);

        stage.show();

    }


public void start(Stage primaryStage) {

        TextArea myTextArea = new TextArea();

        VBox vbox = new VBox();

        vbox.getChildren().add(myTextArea);

        //设置以后跟随外边框增长

        VBox.setVgrow(myTextArea, Priority.ALWAYS);

       

        Scene scene = new Scene(hbox, 320, 112, Color.rgb(0, 0, 0, 0));

        primaryStage.setScene(scene);

        primaryStage.show();

    }

Bordderpane边框窗格

JavaFX BorderPane布局、HyperLink超级链接、Hyper超级、Insets插入、

BorderPane布局顶部，底部，左，右或中心区域中的子节点。每个区域只能有一个节点。BorderPane的顶部和底部区域允许可调整大小的节点占用所有可用宽度。 左边界区域和右边界区域占据顶部和底部边界之间的可用垂直空间。默认情况下，所有边界区域尊重子节点的首选宽度和高度。放置在顶部，底部，左侧，右侧和中心区域中的节点的默认对齐方式如下：

顶部: Pos.TOP_LEFT

底部: Pos.BOTTOM_LEFT

左侧: Pos.TOP_LEFT

右侧: Pos.TOP_RIGHT

中心: Pos.CENTER

案例：

public void start(Stage stage) throws Exception {

        stage.setTitle("borderpane测试");

        Image image = new Image(new FileInputStream("F:\\IDEADemo\\hello\\Snipaste_2022-10-12_20-03-32.jpg"));

        BorderPane borderPane = new BorderPane();

        borderPane.setStyle("-fx-background-color: #330000;");


        HBox top = new HBox();

        top.setMinWidth(30);

        top.setMinHeight(30);

        Text text = new Text("Welcome");

        text.setFont(Font.font("宋体", FontWeight.BOLD,30));

        top.setStyle("-fx-background-color: #336699;");

        //设置top居中

        top.setAlignment(Pos.CENTER);

        top.getChildren().addAll(text);


        VBox letf = new VBox();

        letf.setMinWidth(50);

        letf.setStyle("-fx-background-color: #226699;");

        Button b1 =new Button("改色");

        Button b2 = new Button("改色");

        Button b3 = new Button("改色");

        Button b4 = new Button("改色");

        letf.getChildren().addAll(b1,b2,b3,b4);




        VBox right = new VBox();

        Button r1 =new Button("11");

        Button r2 = new Button("22");

        Button r3 = new Button("33");

        Button r4 = new Button("44");

        right.setStyle("-fx-background-color: #111199;");

        right.setMinWidth(50);

        right.getChildren().addAll(r1,r2,r3,r4);


        HBox Bottom= new HBox();

        Hyperlink hl = new Hyperlink("www.baidu.com");

        Bottom.getChildren().addAll(close,hl);

        Bottom.setAlignment(Pos.CENTER);


       GridPane Center = new GridPane();

       Center.setMinWidth(350);



        borderPane.setTop(top);

        borderPane.setLeft(letf);

       // borderPane.setRight(right);

        borderPane.setBottom(Bottom);

        borderPane.setCenter(Center);


        b1.setOnAction((e)->{

            Center.setStyle("-fx-background-color: #113339;");

        });

        b2.setOnAction((e)->{

        });

        //获取鼠标移动坐标

        Center.addEventFilter(MouseEvent.MOUSE_MOVED, e->{

            String xy="鼠标坐标为:"+e.getX()+","+e.getY();

            text.setText(xy);

            text.setLayoutX(e.getX()+70);

            text.setLayoutY(e.getY()+70);

        });



        Scene scene =new Scene(borderPane,400,300);

        stage.getIcons().add(image);

        stage.setScene(scene);

        stage.show();

    }

GirdPane布局

Gird网格、pane窗格、Lines线、Visible可见的、ColumnConstraints列约束、priority优先事项、always总是、column列、

网格布局

GridPane通常用于布局：表单布局

GridPane可以在行，列或单元格级别指定约束。
例如，我们可以设置包含输入文本字段的第二列，以在窗口调整大小时调整大小。

使用Java FX创建表格的时候，这个布局非常方便。

包javafx.scene.layout名为GridPane这个类提供了 11 个属性，它们是 -

• alignment- 此属性可以设置位置，使用方式setAlignment()方法设置此属性的值。

放置在顶部，底部，左侧，右侧和中心区域中的节点的默认对齐方式如下：

• • • 顶部: Pos.TOP_LEFT
    • 底部: Pos.BOTTOM_LEFT
    • 左侧: Pos.TOP_LEFT
    • 右侧: Pos.TOP_RIGHT
    • 中心: Pos.CENTER
• hgap- 此属性的类型为double，表示列之间的水平差距。
• vgap- 属性的类型为double，它表示行之间的垂直间距。
• gridLinesVisible- 此属性是布尔类型，显示表格线

案例一：

public class GridPanedemo extends Application {

    @Override

    public void start(Stage stage) throws Exception {

        stage.setTitle("gridpane测试");

        BorderPane borderpane = new BorderPane();

        GridPane gridPane = new GridPane();

        gridPane.setStyle("-fx-background-color: #C0C0C0;");


        //表格实线

        gridPane.setGridLinesVisible(true);

        gridPane.setPadding(new Insets(5));

        //水平间距

        gridPane.setHgap(5);

        //垂直间距

        gridPane.setVgap(50);


        //3列

        ColumnConstraints column1 = new ColumnConstraints(100);

        ColumnConstraints column2 = new ColumnConstraints(50, 150, 300);

        ColumnConstraints column3 = new ColumnConstraints(100);


        column2.setHgrow(Priority.ALWAYS);

        gridPane.getColumnConstraints().addAll(column1, column2,column3);


        Label userNameLabel = new Label("用户名");

        TextField userNameField = new TextField();

        Label passwordLabel = new Label("密码");

        gridPane.add(userNameLabel, 0, 0);

        gridPane.add(userNameWarn,3,0);

        gridPane.add(passwordWarn,3,1);

        GridPane.setHalignment(userNameField, HPos.RIGHT);

        gridPane.add(userNameField, 1, 0);


        // passwordLabel

        GridPane.setHalignment(passwordLabel, HPos.LEFT);

        // passwordField

        GridPane.setHalignment(passwordField, HPos.LEFT);

        gridPane.add(passwordField, 1, 1);


        // Save button

        GridPane.setHalignment(saveButt, HPos.RIGHT);

     Button b2 =new Button("b2");

    

     //锚点布局

     AnchorPane anchorPane =new AnchorPane();

     anchorPane.setStyle("-fx-background-color:#e8f2fe");

     anchorPane.getChildren().addAll(b1,b2);

     //距离Top10.0--可以自动适配屏幕大小

     anchorPane.setTopAnchor(b1, 10.0);

     anchorPane.setLeftAnchor(b1, 10.0);

     anchorPane.setBottomAnchor(b2, 10.0);

     //设置内边距

     anchorPane.setPadding(new Insets(10));

     //false解除父类对b1的管理

     //b1.setManaged(false);

     //false不可见

     //b1.setVisible(false);

     //设置透明度

     b1.setOpacity(0.1);

     anchorPane.setOnMouseClicked(new EventHandler<MouseEvent>() {

    

        @Override

        public void handle(MouseEvent event) {

           System.out.println("被点击了");

          

        }

     });

     Scene scene =new Scene(anchorPane,300,400);

     stage.setScene(scene);

     stage.show();

TextFlow布局类

public void start(Stage stage) throws Exception {

     stage.setTitle("TextFlowDemo");

     Text t1 =new Text("t1");

     Text t2 =new Text("t2freagrthbagragargaefacw");

     Text t3 =new Text("t3");

     t1.setFont(Font.font(20));

     t1.setFill(Paint.valueOf("#f8f8f8"));

    

     TextFlow textFlow =new TextFlow();

     textFlow.setStyle("-fx-background-color:#e1e6f6");

     textFlow.getChildren().addAll(t1,t2,t3);
