Eclipse plugin 笔记

1. 取得当前plugin的状态保存地AutoDAOUIPlugin.getDefault().getStateLocation().toFile().getAbsolutePath()
     
2.  打开一个对话框MessageDialog.openError(getShell(), "错误信息", "数据库连接设置错误!"),同样也可以使用静态类MessageDialog打开一个普通的消息对话框
3. 在当前上下文中打开一个对话框NewDriverWizard wizard = new NewDriverWizard();

   		wizard.setNeedsProgressMonitor(true);
   		WizardDialog wizardDialog = new WizardDialogAutoDAOLocation(shell, wizard, 600, 650); //$NON-NLS-1$
   		wizardDialog.setMinimumPageSize(500, 550);
   		wizardDialog.open();

     构造函数WizardDialogAutoDAOLocation的第二个参数类型是org.eclipse.jface.wizard.IWizard
4. 打开一个SWT Composit框，放置几个按钮 

   import org.eclipse.swt.SWT;
   import org.eclipse.swt.layout.RowLayout;
   import org.eclipse.swt.widgets.Button;
   import org.eclipse.swt.widgets.Display;
   import org.eclipse.swt.widgets.Shell;
   
   public class LayoutExample {
       public static void main(String[] args) {
           Display display = new Display();
           Shell shell = new Shell(display);
           // Create the layout.
           RowLayout layout = new RowLayout();
           // Optionally set layout fields.
           layout.wrap = true;
           // Set the layout into the composite.
           shell.setLayout(layout);
           // Create the children of the composite.
           new Button(shell, SWT.PUSH).setText("B1");
           new Button(shell, SWT.PUSH).setText("Wide Button 2");
           new Button(shell, SWT.PUSH).setText("Button 3");
           shell.pack();
           shell.open();
           
           while (!shell.isDisposed()) {
               if (!display.readAndDispatch()) display.sleep();
           }
       }
   }

    
5. 代码里面是怎么实现F5的效果?
   当生成了代码，之后必须手动去目录结构上按一下F5才能将最新生成的代码显示出来。这个如何通过JDT的代码实现？

   		org.eclipse.core.resources.IResource resource = javaProject
   				.getProject().getFolder(srcFolder);
   
   		resource.refreshLocal(IResource.DEPTH_INFINITE,
   				new NullProgressMonitor());
