給eclipse 做個日曆的外掛程式

昨天看了 coldfusion 論壇的一個文章（http://www.5d.cn/bbs/newsdetail.asp?id=980498），誘發了寫一個簡單 eclipse 外掛程式的想法。

這是昨天晚上寫的程式



雖然沒有太大必要，但是還是有點用的，我把這個程式改造了一下，寫了個 eclipse 外掛程式


CalendarView.java

package com.eiffelqiu.tools;

import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.SWT;
import org.eclipse.ui.part.ViewPart;

/**
 * Calendar plugin for eclipse
 * 
 * @author Qiu Hai Feng
 * @version 1.0, Created on 2003-10-28 15:36:57
 */
public class CalendarView extends ViewPart {
 Label label;
 public CalendarView() {
 }
 public void createPartControl(Composite parent) {
 label = new Label(parent, SWT.WRAP);
 label.setText(CalendarImp.show());
 }
 public void setFocus() {

 }

}

CalendarImp.java

package com.eiffelqiu.tools;

import java.util.*;

/**
 * Calendar implementation 
 * 
 * @author Qiu Hai Feng
 * @version 1.0, Created on 2003-10-28 15:36:57
 */
public class CalendarImp {
 /**
 * concate calendar output string
 * 
 * @param void
 * @return String
 */ 
 public static String show() {

 StringBuffer calString = new StringBuffer();
 GregorianCalendar nowDate = new GregorianCalendar();

 int today = nowDate.get(Calendar.DAY_OF_MONTH);
 int month = nowDate.get(Calendar.MONTH);

 nowDate.set(Calendar.DAY_OF_MONTH, 1);
 int weekday = nowDate.get(Calendar.DAY_OF_WEEK);
 calString.append("Sun Mon Tue Wed Thu Fri Sat/n" );
 // indent first line of calendar
 for (int i = Calendar.SUNDAY; i < weekday; i++)
 calString.append(" " );
 do {
 // print the day
 int day = nowDate.get(Calendar.DAY_OF_MONTH);
 if (day < 10)
 calString.append(" " );
 calString.append( " " + day);
 // mark current day with *
 if (day == today)
 calString.append("* " );
 else
 calString.append(" " );
 if (weekday == Calendar.SATURDAY)
 calString.append("/n" );
 // advanced d to next day
 nowDate.add(Calendar.DAY_OF_MONTH, 1);
 weekday = nowDate.get(Calendar.DAY_OF_WEEK);
 } while (nowDate.get(Calendar.MONTH) == month);

 if (weekday != Calendar.SUNDAY)
 calString.append("/n" );

 return calString.toString();
 }

}

測試案例：

package com.eiffelqiu.tools;

import junit.framework.TestCase;

/**
 * Calendar implementation 
 * 
 * @author Qiu Hai Feng
 * @version 1.0, Created on 2003-10-28 15:36:57
 */
public class CalendarImpTest extends TestCase {

 /**
 * Constructor for CalendarImpTest.
 * @param name
 */
 public CalendarImpTest(String name) {
 super(name);
 }

 public static void main(String[] args) {
 junit.swingui.TestRunner.run(CalendarImpTest.class);
 }

 /*
 * @see TestCase#setUp()
 */
 protected void setUp() throws Exception {
 super.setUp();
 }

 /*
 * @see TestCase#tearDown()
 */
 protected void tearDown() throws Exception {
 super.tearDown();
 }

 public void testShow() {
 assertTrue(!CalendarImp.show().equals(null));
 assertEquals(CalendarImp.show(),CalendarImp.show());
 }

}
