(1) master the GUI layout manager usage; (2) master Java Swing text input components and common use the API; (3) Java Swing control to select an input component and use common API. |
Part I: summary of Chapter XII week of theoretical knowledge
Swing and MVC design pattern
(1) design patterns (Design pattern ) designer is a popular way of thinking about design issues, is set to be repeated use, known to most people, after cataloging, code design experience summary.
(2) Model - View - Controller design pattern (Model -ViewController) is to create Web applications under Java EE platform important design patterns.
(. 3) the MVC design pattern - Model (Model): is a portion of the processing program logic program data, the model is typically responsible for accessing data in a database.
- View (View) : is a partial data processing program, based on the model view data is typically accessed created.
- the Controller (Controller) : the program is part of the user interaction processing. Typically the controller is responsible for reading data from the view, a user input control, and the transmission data model.
(4) Java components have content, appearance, behavior, three main elements;
Layout Manager
(1) is a set of layout manager class . - implement java.awt.LayoutManager Interface - a container assembly determines the position and size
Java.awt package layout manager defines five classes, each class corresponding to the layout of one layout management strategy.
Each container has associated with the default layout manager.
(2) five kinds of layout manager: (. 1) the FlowLayout : flow layout (Applet and Panel default layout manager) (2) the BorderLayout: border layout (Window, Frame and Dialog default layout manager) (. 3) GridLayout: grid layout (. 4) the GridBagLayout : group grid layout (. 5) A CardLayout : card layout
. 3, GridLayout constructor as follows:. 1, GridLayout () : generating a grid layout of a single separate
2, GridLayout (int rows, int cols): generating a grid layout set number of rows and columns
. 3, GridLayout (int rows, int Columns, hgap int, int vgap): may be provided between the horizontal and vertical spacing of the components
Text Input
(1) Text field (JTextField): for obtaining single-line text input.
(2) the text area (JTextArea) component lets users input multiple lines of text. Generating JTextArea component object, the text area can be specified number of rows and columns: textArea = new JTextArea (8, 40);
(3) Comparison between the text area text fields in common: text fields and text areas can be used to obtain the text input components.
Except: receiving an input text field single line of text only; text input region capable of accepting multiple lines of text.
(4) common text area JTextArea the API: . Java.swing JTextArea 1.2 - JTextArea (int rows, int cols)
A text region constructed objects row rows cols columns - the JTextArea (String text, int rows, int cols)
A text region constructed with initial text objects - void the setRows (int rows)
Set the number of lines of text fields use - void the append (String newText)
Append to the text given later in the text in the text area - void setLineWrap (Boolean wrap)
Open or closed wrap
(5) Label components: a component receiving text label. Without any modification thereof (e.g., no boundaries), nor in response to user input.
One common use is to identify the component label, such as identification text field. Using the following steps:
1. Create a JLabel component
2. The tag assembly is placed at a distance close enough to identify the component.
(6) password field: password field is a special type of text field. Each character entered with echo characters to achieve a typical echo characters *.
– JPassWordField(String text, int columns） 构造一个密码域对象
（7）滚动窗格：
Swing中文本区没有滚动条，若需要滚动条。将文 本区放入一个滚动窗格中即可。
常用API—Java.swing. JScrollPane(教材340页) – JScrollPane(Component c) 在组件c上添加滚动条，返回添加后的组件。
选择组件
复选框 单选按钮 边框 组合框 滑动条
（1）复选框构造器 1.bold = new JCheckBox("Bold"); 复选框自动地带有表示标签。
2. JCheckBox(String label,Icon icon); 构造带有标签与图标的复选框，默认初始未被选择。
3.JCheckBox(String label,boolean state); 用指定的标签和初始化选择状态构造一个复选框
（2）单选按钮的构造器（教材492页） 1.JRadioButton(String label,Icon icon); 创建一个带标签和图标的单选按钮
2.JRadioButton(String label,boolean state); 用指定的标签和初始化状态构造单选按钮
（3）按钮组：为单选按钮组构造一个ButtonGroup的对象。 然后，再将JRadioButton类型的对象添加到按钮 组中。按钮组负责在新按钮被按下的时，取消前一 个按钮的选择状态。
（4）如果在一个窗口中 有多组复选框或单选按 钮，就需要可视化的形 式指明哪些按钮属于同 一组。Swing提供了一 组很有用的边框
（5）如果有多个选择项，使用单选按钮占据的屏幕空 间太大时，就可以选择组合框。
faceCombo = new JComboBox()； faceCombo.setEditable(true);
让组合框可编辑 faceCombo.addItem("Serif"); faceCombo.insertItemAt("Monospace",0);
增加组合框选项 faceCombo.removeItem("Monospace");
faceCombo.removeItemAt(0); 删除组合框选项内容
（6）组合框的事件监听：为了判断组合框的哪个选项被选择，可通过 事件参数调用getSource方法来得到发送事件的组 合框引用，接着调用getSelectdeItem方法获取当 前选择的选项。
（7）滑动条：滑动条可以让用户从一组离散值中进行选择 ，并且它还允许进行连续值得选择。
菜单
菜单创建 菜单项中的图标 复选框和单选按钮菜单项 弹出菜单 快捷键和加速器 启用和禁用菜单项 工具栏 工具提示
网格组布局 (GridBagLayout):GridBagLayout与GridLayout有点相似，它也是 将组件排在格子里，但是GridBagLayout在网格 的基础上提供更复杂的布局。
GridBagLayout允许单个组件在一个单元中不填 满整个单元，而只是占用最佳大小，也允许单个 组件扩展成不止一个单元，并且可以用任意顺序 加入组件。
定制布局管理器: 程序员可通过自己设计LayoutManager类来实现 特殊的布局方式。
定制布局管理器需要实现LayoutManager接口， 并覆盖以下方法。
对话框
选项对话框 创建对话框 数据选择 文件对话框 颜色选择器
(1)对话框是一种大小不能变化、不能有菜单的容器窗口； 对话框不能作为一个应用程序的主框架，而必须包含在其 他的容器中。
(2)选项对话框:JOptionPane提供的对话框是模式对话框。当模 式对话框显示时，它不允许用户输入到程序的 其他的窗口。使用JOptionPane，可以创建和自 定义问题、信息、警告和错误等几种类型的对 话框。
(3)数据交换:输入对话框含有供用户输入文本的文本框、一个确认和取 消按钮,是有模式对话框。当输入对话框可见时,要求用户 输入一个字符串。
(4)文件对话框:专门用于对文件（或目录）进行浏览和选择的对 话框，常用的构造方法: – JFileChooser()：根据用户的缺省目录创建文件对话框 – JFileChooser(File currentDirectory)：根据File型参数 currentDirectory指定的目录创建文件对话框
(5)颜色对话框: javax.swing包中的JColorChooser类的静态方 法: public static Color showDialog(Component component, String title, Color initialColor)创建一个颜色对话框
(6)参数component指定对话框所依赖的组件，title 指定对话框的标题；initialColor 指定对话框返回 的初始颜色，即对话框消失后，返回的默认值。 颜色对话框可根据用户在颜色对话框中选择的颜 色返回一个颜色对象.

实验2：结对编程练习
利用所掌握的GUI技术，设计一个用户信息采集程序，要求如下：
（1） 用户信息输入界面如下图所示:
（2） 用户点击提交按钮时，用户输入信息显示在录入信息显示区，格式如下:
（3）用户点击重置按钮后，清空用户已输入信息；
（4） 点击窗口关闭，程序退出。
结对编程练习包含以下4部分：
1) 程序设计思路简述；
运用GridLayout布局，北边放JTextField（用以处理姓名和地址）以及JLabel，还有性别按钮（此为单选按钮用以处理性别选择）和爱好按钮（此为复选按钮用以处理爱好选择），南边放一个JTextArea（用以打印提交后的信息显示），总归就是把前几个示例代码糅合在一起写出来的。

实验总结：
通过这一章的理论学习，在学习过程中，自己对理论知识的学习学的比较混乱，混淆了这几部分的学习内容。另外，对于本周的实验，实验都有很多相同和类似的地方，在实验过程中任然没有理解的太清楚。在查了课本上的内容之后，稍微有了掌握。以后会更加努力。
