IAction与IActionDelegate PropertyTester

非常好的，可以很好的参考如何写eclipse plugin

http://blog.csdn.net/kevin99zhang/archive/2007/11/28/1905638.aspx RCP console 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
写道
public void createPartControl(Composite parent) {
toolkit = new FormToolkit(parent.getDisplay());

form.setText("Snippet8");

// create a tooltip
