接上次的例子，我们实现一个自定义页面。 第一步添加类： 右击包com.hwcrazy.editor.editors，选择New-》Class，填写类名。如下：
点击Finish。 类的内容这么写：
package com.hwcrazy.editor.editors;
import java.io.IOException;
import javax.swing.event.HyperlinkEvent;
import org.eclipse.swt.SWT;
import org.eclipse.swt.layout.GridData;
import org.eclipse.swt.layout.GridLayout;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.widgets.Text;
import org.eclipse.ui.forms.IManagedForm;
import org.eclipse.ui.forms.editor.FormPage;
import org.eclipse.ui.forms.events.HyperlinkAdapter;
import org.eclipse.ui.forms.widgets.FormToolkit;
import org.eclipse.ui.forms.widgets.Hyperlink;
import org.eclipse.ui.forms.widgets.ScrolledForm;
import org.eclipse.ui.forms.widgets.TableWrapData;
import org.eclipse.ui.forms.widgets.TableWrapLayout;
public class InfoPage extends FormPage {
InfoPage(HwDbEditor editor, String id) {
super(editor, id, "信息");
}
protected void createFormContent(IManagedForm managedForm) {
// 一下内容按自己高兴
FormToolkit toolkit = managedForm.getToolkit();
ScrolledForm form = managedForm.getForm();
toolkit.decorateFormHeading(form.getForm());
form.setText("项目基本信息以及计划");
TableWrapLayout layout = new TableWrapLayout();
form.getBody().setLayout(layout);
Hyperlink link = toolkit.createHyperlink(form.getBody(),
"HelloWorld论坛", SWT.WRAP);
link.addHyperlinkListener(new HyperlinkAdapter() {
public void linkEntered(HyperlinkEvent e) {
// 光标进入超链接区域
System.out.println("光标进入超链接区域");
}
public void linkExited(HyperlinkEvent e) {
// 光标离开超链接区域
System.out.println("光标离开超链接区域");
}
public void linkActivated(HyperlinkEvent e) {
// 单击超链接激活时
System.out.println("超链接被激活");
try {
Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler http://hwcrazy.com/");
} catch (IOException e1) {
e1.printStackTrace();
}
//判断当前系统是否支持Java AWT Desktop扩展
if(java.awt.Desktop.isDesktopSupported()){
try{
//创建一个URI实例,注意不是URL
java.net.URI uri=java.net.URI.create("http://hwcrazy.com");
//获取当前系统桌面扩展
java.awt.Desktop dp=java.awt.Desktop.getDesktop();
//判断系统桌面是否支持要执行的功能
if(dp.isSupported(java.awt.Desktop.Action.BROWSE)){
//获取系统默认浏览器打开链接
dp.browse(uri);
}
}catch(java.lang.NullPointerException e1){
//此为uri为空时抛出异常
}catch(java.io.IOException e1){
//此为无法获取系统默认浏览器
}
}
}
});
layout.numColumns = 2;
TableWrapData td = new TableWrapData();
td.colspan = 2;
link.setLayoutData(td);
// form.setImage(inputData.getImageDescriptor().createImage());
GridData gridData6 = new GridData();
gridData6.horizontalSpan = 3;
gridData6.horizontalAlignment = org.eclipse.swt.layout.GridData.FILL;
GridLayout gridLayout3 = new GridLayout();
gridLayout3.numColumns = 6;
Composite composite2 = toolkit.createComposite(form.getBody());
composite2.setLayout(gridLayout3);
// Composite composite2 = section;
toolkit.createLabel(composite2, "计划开始:");
Text textPStart = toolkit.createText(composite2, "2009-12-30 12:30:30",
SWT.SINGLE | SWT.BORDER);
textPStart.setLayoutData(new GridData(SWT.FILL, SWT.BEGINNING, true,
false));
toolkit.createLabel(composite2, "计划完成:");
Text textPFinish = toolkit.createText(composite2,
"2009-12-30 12:30:30", SWT.SINGLE | SWT.BORDER);
textPFinish.setLayoutData(new GridData(SWT.FILL, SWT.BEGINNING, true,
false));
toolkit.createLabel(composite2, "工期:");
Text textDur = toolkit.createText(composite2, "2d", SWT.SINGLE
| SWT.BORDER);
textDur.setLayoutData(new GridData(SWT.FILL, SWT.BEGINNING, true, false));
toolkit.createLabel(composite2, "实际开始:");
Text textAStart = toolkit.createText(composite2,
"2009-12-30 12:30:30", SWT.SINGLE | SWT.BORDER);
textAStart.setLayoutData(new GridData(SWT.FILL, SWT.BEGINNING, true,
false));
toolkit.createLabel(composite2, "实际完成:");
Text textAFinish = toolkit.createText(composite2,
"2009-12-30 12:30:30", SWT.SINGLE | SWT.BORDER);
textAFinish.setLayoutData(new GridData(SWT.FILL, SWT.BEGINNING, true,
false));
toolkit.createLabel(composite2, "历时:");
Text textADur = toolkit.createText(composite2, "0.5d", SWT.SINGLE
| SWT.BORDER);
textADur.setLayoutData(new GridData(SWT.FILL, SWT.BEGINNING, true,
false));
toolkit.createLabel(composite2, "负责人:");
Text textManager = toolkit.createText(composite2, null, SWT.SINGLE
| SWT.BORDER);
textManager.setLayoutData(new GridData(SWT.FILL, SWT.BEGINNING, true,
false));
toolkit.createLabel(composite2, "负责部门:");
Text textDept = toolkit.createText(composite2, null, SWT.SINGLE
| SWT.BORDER);
textDept.setLayoutData(gridData6);
toolkit.createLabel(composite2, "项目团队:");
Text textTeam = toolkit.createText(composite2,
"测试显示长文本的状况>测试显示长文本的状况>测试显示长文本的状况>测试显示长文本的状况>测试显示长文本的状况",
SWT.SINGLE | SWT.BORDER);
GridData gd = new GridData(SWT.FILL, SWT.BEGINNING, false, false, 5, 1);
gd.widthHint = 400;
textTeam.setLayoutData(gd);
}
}
然后，HwDbEditorz中的addPages方法修改为：
@Override
protected void addPages() {
// TODO Auto-generated method stub
try {
addPage(new FormPage(this, "1", "计划"));
addPage(new FormPage(this, "2", "任务"));
addPage(new InfoPage(this, "3"));
} catch (PartInitException e) {
e.printStackTrace();
}
}
运行界面如下：
有个疑问就是我调试了半天，点击HelloWorld论坛，没有反应，请高人帮忙看看！ |
