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 {@Overridepublic 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();}}

案例

public class HBoxDemo extends Application {@Overridepublic 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));hbox.setMargin(text,new Insets(10,0,0,0));hbox.getChildren().addAll(button,text);Scene scene = new Scene(group,500,400);stage.setScene(scene);stage.show();}public static void main(String[] args) {launch();}}

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;");VBox vbox = new VBox(50);vbox.setMinWidth(100);vbox.setMinHeight(400);vbox.setStyle("-fx-background-color: #330000;");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.setMinHeight(30);Bottom.setStyle("-fx-background-color: #113339;");Button close = new Button("关闭系统");close.setOnAction((e)->{Platform.exit();});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)->{Center.setStyle("-fx-background-color: #222239;");});b3.setOnAction((e)->{Center.setStyle("-fx-background-color: #333339;");});b4.setOnAction((e)->{Center.setStyle("-fx-background-color: #444439;");});//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 {@Overridepublic 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");PasswordField passwordField =new PasswordField();Text userNameWarn = new Text("用户名不能为空");Text passwordWarn = new Text("密码不能空");Button saveButt = new Button("保存");// userNameLabel  列 行GridPane.setHalignment(userNameLabel, HPos.RIGHT);gridPane.add(userNameLabel, 0, 0);gridPane.add(userNameWarn,3,0);gridPane.add(passwordWarn,3,1);// userNameFieldGridPane.setHalignment(userNameField, HPos.RIGHT);gridPane.add(userNameField, 1, 0);// passwordLabelGridPane.setHalignment(passwordLabel, HPos.LEFT);gridPane.add(passwordLabel, 0, 1);// passwordFieldGridPane.setHalignment(passwordField, HPos.LEFT);gridPane.add(passwordField, 1, 1);// Save buttonGridPane.setHalignment(saveButt, HPos.RIGHT);gridPane.add(saveButt, 1, 2);borderpane.setCenter(gridPane);Scene scene =new Scene(borderpane,600,500);stage.setScene(scene);stage.show();}public static void main(String[] args) {launch();}}

案例二、
