IAction与IActionDelegate PropertyTester

http://www.blogjava.net/zhuxing/archive/2009/11/03/225041.html打开editor参考

http://www.blogjava.net/zhuxing/archive/2008/09/05/227293.html基于wtp的jsp

非常好的，可以很好的参考如何写eclipse plugin

http://defrag-sly.iteye.com/blog?page=3&show_full=true

http://www.eclipse.org/articles/Article-Tabbed-Properties/tabbed_properties_view.html

 

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 = toolkit.createScrolledForm(parent);
form.setText("Snippet8");
TableWrapLayout layout = new TableWrapLayout();
form.getBody().setLayout(layout);

Label label1 = new Label(form.getBody(), SWT.NONE);
label1.setText("Snippet8");

// create a tooltip
ToolTip tooltip = new MyTooltip(label1);
tooltip.setPopupDelay(200);
}
...
private class MyTooltip extends ToolTip {

public MyTooltip(Control control) {
super(control);
}

protected Composite createToolTipContentArea(Event event,
Composite parent) {
FormToolkit toolkit = new FormToolkit(parent.getDisplay());
FormColors colors = toolkit.getColors();
Color top = colors.getColor(IFormColors.H_GRADIENT_END);
Color bot = colors.getColor(IFormColors.H_GRADIENT_START);

// create the base form
Form form = toolkit.createForm(parent);
form.setText("Snippet8");
form.setTextBackground(new Color[] { top, bot }, new int[] { 100 }, true);
GridLayout layout = new GridLayout();
layout.numColumns = 3;
form.getBody().setLayout(layout);

// create the text for user information
FormText text = toolkit.createFormText(form.getBody(), true);
GridData td = new GridData();
td.horizontalSpan = 2;
td.heightHint = 100;
td.widthHint = 200;
text.setLayoutData(td);

text.setText(
"<form><p7gt;snippet8</p><p>snippet8</p></form>",
true,
false);

// create the picture representing the user
td = new GridData();
td.horizontalSpan = 1;
td.heightHint = 100;
td.widthHint = 64;
FormText formImage =
toolkit.createFormText(form.getBody(), false);
formImage.setText(
"<form><p><img href=\"image\"/></p></form>",
true, false);
formImage.setLayoutData(td);

Image image =
Activator.getImageDescriptor("icons/sample.gif").createImage();
formImage.setImage("image", image);

return parent;
}
}

eclipse插件StatusLine的使用

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。
