本文档详述了Eclipse插件开发的关键技术点，包括如何实现编辑器操作、视图操作、弹出菜单功能，以及如何配置插件属性检测器。此外，还介绍了如何在Eclipse中设置自定义的状态栏文本、实现表单和表格的提示功能。

非常好的，可以很好的参考如何写eclipse plugin

IActionDelegate的子类型是IWorkWindowBenchDelegate为工作台窗口的(actionset)。
editoraction,viewaction,popupmenu(objectaction)
其实不用自己写,可以参考http://hoodman.iteye.com/blog/497405
public class FavoritesTester extends PropertyTester {
public boolean test(Object receiver, String property, Object[] args,
Object expectedValue) {
boolean found = false;
IFavoriteItem[] favorites = FavoritesManager.getManager().getFavorites();
for (int i = 0; i < favorites.length; i++) {
IFavoriteItem item = favorites[i];
found = item.isFavoriteFor(receiver);
if (found)
break;
}
if ("isFavorite".equals(property))
return found;
if ("notFavorite".equals(property))
return !found;
return false;
}
}
这样还不行，还必须在插件里配置，重要的参数是一个namespace和propery。在使用这个检测对像的可见性时需在适当的地方(一般是 <extension
point="org.eclipse.ui.menus">)采用namespace+propery
以下是在监听属选性时更改的代码
private final IPropertyChangeListener propertyChangeListener = new IPropertyChangeListener() {
public void propertyChange(PropertyChangeEvent event) {
if (event.getProperty().equals("HOST")
|| event.getProperty().equals("PORT")
|| event.getProperty().equals("USERNAME")
|| event.getProperty().equals("PASSWORD")) {
System.out.println("event.getProperty():" + event.getProperty());
if (ftpClient.isConnected())
try {
ftpClient.disconnect();
ftpClient = null;
} catch (IOException e) {
e.printStackTrace();
}
ftpClient = initFTPClient();
}
}
};
private FTPClientInstance() {
super();
ftpClient = initFTPClient();
ClassFTPPlugin.getDefault().getPluginPreferences()
.addPropertyChangeListener(propertyChangeListener);
}
以下是找到eclipse中的handle，然后执行的代码
private void hookDoubleClickCommand() {
viewer.addDoubleClickListener(new IDoubleClickListener() {
public void doubleClick(DoubleClickEvent event) {
IHandlerService handlerService = (IHandlerService) getSite()
.getService(IHandlerService.class);
try {
handlerService.executeCommand(
"de.vogella.rcp.intro.editor.callEditor", null);
} catch (Exception ex) {
throw new RuntimeException(
"de.vogella.rcp.intro.editor.callEditor not found");
}
}
});
}另外tooltip的提示有两种，一种是普通的另一种是form

转自：http://www.blogjava.net/zp0127/archive/2007/04/09/109431.html 1、定义静态的StatusLine文本
WorkbenchWindowAdvisor 类中的preWindowOpen（）方法加入 configurer.setShowStatusLine(true);//显示状态栏 ApplicationActionBarAdvisor类中增加 protected void fillStatusLine(IStatusLineManager statusLine) { super.fillStatusLine(statusLine); StatusLineContributionItem statusItem = new StatusLineContributionItem("DAStatus",50); statusItem.setText("状态栏：测试"); statusLine.add(statusItem); } 将在状态栏中显示：“状态栏：测试” 2、定义动态的StatusLine文本 WorkbenchWindowAdvisor 类中的preWindowOpen（）方法加入 configurer.setShowStatusLine(true); 在要调用状态栏的class里加入下面方法 private void showStatusMessage(String msg) { WorkbenchWindow workbenchWindow = (WorkbenchWindow)PlatformUI.getWorkbench().getActiveWorkbenchWindow(); IStatusLineManager lineManager = workbenchWindow.getStatusLineManager(); StatusLineContributionItem statusItem = new StatusLineContributionItem("DAStatus",50); statusItem.setText(msg); lineManager.add(statusItem); } 使用listener来调用showStatusMessage(String msg)即可。
