軟件工程課程設(shè)計3

南京信息工程大學實驗（實習）報告實驗（實習）名稱詳細設(shè)計實驗（實習）日期2013.11.22得分指導教師李振宏一、實驗目的1．通過windows畫圖板進行詳細設(shè)計，掌握算法的設(shè)計方法與算法的描述；2．掌握常用算法描述工具的使用；3.完成一個windows畫圖板的算法設(shè)計。二、實驗準備熟悉算法描述工具的使用三、實驗要求完成windows繪圖板的詳細設(shè)計，提交實驗報告開發(fā)一個功能完善的Windows繪圖板程序，功能包括：新建空白文檔、文件保存、繪制一些基本的圖形組件（直線、矩形、實心矩形、橢圓、實心橢圓、圓、實心圓、圓角矩形、實心圓角矩形等）、橡皮擦、添加文字等實驗內(nèi)容：1:背景根據(jù)實際情況，我們使用原型法即以少量代價快速地構(gòu)造一個可執(zhí)行的軟件系統(tǒng)模型。使用戶和開發(fā)人員可以較快地確定需求，然后采用循環(huán)進化的開發(fā)方式，對系統(tǒng)模型作連續(xù)的改進，將系統(tǒng)需具備的性能逐漸增加上去，直到所有的性能全部滿足。直到所有的性能全部滿足?？傮w規(guī)劃主要實現(xiàn)想法和作編寫代碼的工作。開始2：界面組織結(jié)構(gòu)開始初始化繪圖區(qū)域初始化繪圖區(qū)域打開已有文件打開已有文件新建或默認文件新建或默認文件繪制修改圖片繪制修改圖片保存圖片文件新建文件保存圖片文件新建文件退出程序退出程序結(jié)束結(jié)束Windows繪圖板Windows繪圖板函數(shù)畫圖一般畫圖菜單欄工具欄畫圖區(qū)畫圖板主界面函數(shù)畫圖一般畫圖菜單欄工具欄畫圖區(qū)畫圖板主界面3：界面設(shè)計說明要求其實都知道java并不是做Windows畫圖板的最好的語言，但是因為我們并沒有學過VB，所以只能用JAVA來編寫windows繪圖板這個軟件，Java并沒有VB那么大量的控件，所以我們必須要用JAVA的語言來實現(xiàn)運用了JAVA中類的繼承特性實現(xiàn)了對父類方法的調(diào)用，并多次使用CASE語句實現(xiàn)繪圖菜單的選擇，運用了適配器類簡化了監(jiān)聽器類的重寫工作。4:界面代碼程序importjava.awt.BorderLayout;importjava.awt.Choice;importjava.awt.Color;importjava.awt.Desktop.Action;importjava.awt.FileDialog;importjava.awt.Graphics;importjava.awt.GridLayout;importjava.awt.Polygon;importjava.awt.event.ActionEvent;importjava.awt.event.ActionListener;importjava.awt.event.ItemEvent;importjava.awt.event.ItemListener;importjava.awt.event.KeyEvent;importjava.awt.event.MouseAdapter;importjava.awt.event.MouseEvent;importjava.awt.event.MouseMotionAdapter;importjava.awt.event.WindowAdapter;importjava.awt.event.WindowEvent;importjava.io.File;importjava.io.FileInputStream;importjava.io.FileOutputStream;importjava.io.IOException;importjava.io.ObjectInputStream;importjava.io.ObjectOutputStream;importjava.io.Serializable;importjava.util.Vector;importjavax.swing.AbstractAction;importjavax.swing.Icon;importjavax.swing.ImageIcon;importjavax.swing.JButton;importjavax.swing.JColorChooser;importjavax.swing.JFrame;importjavax.swing.JLabel;importjavax.swing.JMenu;importjavax.swing.JMenuBar;importjavax.swing.JMenuItem;importjavax.swing.JOptionPane;importjavax.swing.JPanel;importjavax.swing.JTextField;importjavax.swing.JToolBar;importjavax.swing.KeyStroke;classPointimplementsSerializable{intx,y;Colorcol;inttool;intguangdu;Point(intx,inty,Colorcol,intguangdu){this.x=x;this.y=y;this.col=col;this.guangdu=guangdu;}publicvoidmove(intx,inty,Colorcol,intguangdu){ this.x=x;
