Eclipse plugin 札记

?

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());
