設置佈局內各個UI組件對齊填充間距方式

1.對齊填充間距概述

Padding：填充-子控件與父級的間距
Spacing：間距-各個子控件之間的間距
Alignment：對齊-上下左右對齊方式

2. 對齊填充Demo

import javafx.application.Application;
import javafx.geometry.Insets;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.TextField;
import javafx.scene.layout.HBox;
import javafx.scene.layout.Priority;
import javafx.stage.Stage;

        HBox hBox = new HBox();

        Button b1 = new Button("創建");
        Button b2 = new Button("修改");
        Button b3 = new Button("刪除");
        Button b4 = new Button("撤銷");

        hBox.getChildren().addAll(textField,b1,b2,b3,b4);

        //padding設置子控件與父級的間距
        hBox.setPadding(new Insets(10,2,30,40));

        //Spacing設置各個組件之間的間距
        hBox.setSpacing(5);

        //Alignment設置對齊方式
        hBox.setAlignment(Pos.CENTER);

        //水平增長佔滿空間
        HBox.setHgrow(textField, Priority.ALWAYS);

        //創建場景
        Scene scene = new Scene(hBox, 700, 700);
        //添加場景到窗口中
        stage.setScene(scene);
        //打開窗口
        stage.show();
    }

    public static void main(String[] args) {
        Application.launch(args);
    }
