我想构建一个插件，它在 Notes 客户端（8.5.2++）加载时加载，每当打开文档时都会调用它并获取该文档的（Notes）URL。我需要哪些扩展点和 API？
澄清：
我确实知道如何访问当前文档（NotesUIWorkspace.currentDocument）。我不知道如何（以及何时）注册一个监听器以获得通知。
特殊挑战：文档可以在 Framesets（多个）中打开，文档可以作为复合页面的一部分打开。框架集不是一个大问题，而是复合。如果这需要听任何页面打开并检查它 - 我很好

我们通过获取任何类型的“帖子选择”的所有请求来解决这个问题。以下代码片段来自侧边栏插件，并在 createViewPart() 中调用：
m_Observer = new NotesSelectionObserverImpl();
NotesSelectionObservable cObservable = new NotesSelectionObservable();
PlatformUI.getWorkbench().getActiveWorkbenchWindow().getSelectionService().addPostSelectionListener(cObservable);
cObservable.addObserver(this.m_Observer);
魔术的第一部分是“PlattformUI ......addPostSelecitonListener();” 在这一点上，我们注册了我们的监听器，witch 也是基于观察者模式的。
class NotesSelectionObserverImpl implements NotesSelectionObserver {
@Override
public void onSelectionChange(NotesSelectionContext cContext)
throws NotesException {
Database ndbCurrent = cContext.getDatabase();
Document docCurrent = cContext.getDocument();
if (ndbCurrent != null && docCurrent != null) {
String strEMail = "";
if (docCurrent.getItemValueString("Form").equals("Memo")
|| docCurrent.getItemValueString("Form")
.equals("Reply")) {
strEMail = docCurrent.getItemValueString("From");
strEMail = parseEMail(strEMail);
System.out.println("EMAIL: " + strEMail);
ContextCommand ccCurrent = new ContextCommand(strEMail,
docCurrent.getItemValueString("Subject"));
m_State.doFeedAction(false, m_Feeds.get(Activator.FEED_CONTEXT_ID), ccCurrent);
}
}
}
@Override
public void onUpdateAfterSelectionChange() {
// TODO Auto-generated method stub
}
}
NotesSelectionObserver 是一个具有以下定义的接口：
import lotus.domino.NotesException;
public interface NotesSelectionObserver
{
void onSelectionChange(NotesSelectionContext cContext) throws NotesException;
void onUpdateAfterSelectionChange();
}
NotesSelecitonContext 是另一个提供有关选择的所有信息的接口。这里的定义：
import lotus.domino.Database;
import lotus.domino.Document;
public interface NotesSelectionContext
{
public Database getDatabase();
public Document getDocument();
public String getField();
}
所以现在最后一部分，女巫是线索.... NotesSelectionObservable：
import java.net.MalformedURLException;
import java.net.URL;
import java.util.StringTokenizer;
import java.util.Vector;

您还询问了插件列表：
org.eclipse.ui,
org.eclipse.core.runtime,
com.ibm.notes.java.api;bundle-version="1.5.1",
com.ibm.notes.java.ui;bundle-version="8.5.1",
com.ibm.csi;bundle-version="1.5.1",
com.ibm.notes.client;bundle-version="8.5.1"
我们还将将此代码作为插件带到 openNTF 社区。我认为任何想要通过侧边栏扩展notesclient 的人都需要了解用户所在的女巫上下文并希望对此上下文做出响应。
