作业学习目标

(1)掌握GUI布局管理器用法;

(2)掌握Java Swing文本输入组件用途及常用API;

(3)掌握Java Swing选择输入组件用途及常用API;

 

第一部分:总结第十二章本周理论知识(25分)

12.1.Swing和MVC设计模式

a 设计模式初识
b 模型—视图—控制器模式
c Swing组件的模型—视图—控制器分析

 

12.2布局管理器

a 布局管理器是一组类。

b 实现java.awt.LayoutManager接口

c 决定容器中组件的位置和大小

d Java.awt包中定义了5种布局管理类,每一种布 局管理类对应一种布局策略。 

e 每个容器都有与之相关的默认布局管理器。

f 当一个容器选定一种布局策略时,它应该创建该 策略对应的布局管理器对象,并将此对象设置为 自己的布局管理器。

g 5种布局管理器

(1)FlowLayout:流布局(Applet和Panel的默认 布局管理器)

(2)BorderLayout:边框布局(Window、Frame和 Dialog的默认布局管理器)

(3)GridLayout:网格布局

(4)GridBagLayout:网格组布局

(5)CardLayout:卡片布局

 

 

12.3文本输入

a 域

b 文本区 

c 标签与标签组件

d 密码域

e 滚动窗格

 

12.4选择组件

a 复选框

b 单选按钮

c 边框

d 组合框 

e 滑动条

12.5菜单

a 菜单创建

b 菜单项中的图标

c 复选框和单选按钮菜单项

d 弹出菜单

e 快捷键和加速器

f 启用和禁用菜单项

g工具栏

h 工具提示

 

12.5对话框

a 选项对话框

b 创建对话框

c 数据选择

d 文件对话框 e 颜色选择器

 

第二部分:实验部分

实验1:测试程序1(5分)

1.在elipse IDE中运行教材479页程序12-1,结合运行结果理解程序;

2.掌握各种布局管理器的用法;

3.理解GUI界面中事件处理技术的用途。

4.在布局管理应用代码处添加注释;

实验总结:(10分)

        通过本周的学习,掌握了线程概念和线程创建;理解了基础线程的优先级属性及调度方法;学会了Java GUI 编程技术的基础及Swing图形界面组件相关知识。现在掌握的知识内容比之前多,所以容易混淆记不住,在编写程序的时候就经常丢三落四导致浪费了很多时间。在程序编写的条理性方面还有待加强,代码需要更多的自我消化,不然也不是自己的东西。
