FlowPane

FlowPane将结点按照加入的次序,水平方向从左到右水平或者垂直方向从上到下地放置。

package Chap14;

import Chap12.Test;
import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.control.TextField;
import javafx.scene.layout.FlowPane;
import javafx.stage.Stage;

public class ShowFlowPane extends Application {
    @Override
    public void start(Stage primaryStage) throws Exception {
        FlowPane pane = new FlowPane();
        //创建一个Insets并给出边框大小(顶、右、底、左)
        pane.setPadding(new Insets(11,12,13,14));
        //水平间距
        pane.setHgap(5);
        //垂直间距
        pane.setVgap(5);

        //Place nodes in the pane
        pane.getChildren().addAll(new Label("First Name:"),new TextField(),new Label("MI:"));
        //显式引用,因为要来设置属性
        TextField tfmi = new TextField();
        //将MI文本域的首选列数设置为1
        tfmi.setPrefColumnCount(1);
        pane.getChildren().addAll(tfmi,new Label("Last Name:"),new TextField());

        //Creat a scene and place it in the stage
        Scene scene = new Scene(pane,200,250);
        primaryStage.setTitle("ShowFlowPane");
        primaryStage.setScene(scene);
        primaryStage.show();
    }
}

GridPane

GridPane将结点安排在一个网格(矩阵)结构中。结点放在一个指定下标的列和行中。

package Chap14;

import javafx.application.Application;
import javafx.geometry.HPos;
import javafx.geometry.Insets;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.control.TextField;
import javafx.scene.layout.GridPane;
import javafx.stage.Stage;

public class ShowGridPane extends Application {
    @Override
    public void start(Stage primaryStage) throws Exception {
        GridPane pane = new GridPane();
        //对齐方式设为居中
        pane.setAlignment(Pos.CENTER);
        pane.setPadding(new Insets(11.5,12.5,13.5,14.5));
        pane.setHgap(5.5);
        pane.setVgap(5.5);

        //将标签置于0行0列
        pane.add(new Label("First Name:"),0,0);
        pane.add(new TextField(),1,0);
        pane.add(new Label("MI:"),0,1);
        pane.add(new TextField(),1,1);
        pane.add(new Label("Last Name:"),0,2);
        pane.add(new TextField(),1,2);
        Button btAdd = new Button("Add Name");
        pane.add(btAdd,1,3);
        //将按钮在单元格中右对齐
        GridPane.setHalignment(btAdd, HPos.RIGHT);

        //创建场景并放在舞台
        Scene scene = new Scene(pane);
        primaryStage.setTitle("ShowGridPane");
        primaryStage.setScene(scene);
        primaryStage.show();//Display the stage
    }
}
