Question

我正在开发一个显示ViewParts和EditorParts的RAP应用程序。我试图找到一种方法来阻止“所有”编辑器部件关闭。有没有办法删除或禁用编辑器部分显示“X”关闭按钮？

Answer 1

你可以这样做（我写的内容大致相同：http://wiki.eclipse.org/RCP_Custom_Look_and_Feel）：在ApplicationWorkbenchWindowAdvisor类中，您可以注册自己的PresentationFacory，如：

  public void preWindowOpen() {    
    WorkbenchAdapterBuilder.registerAdapters();    
    IWorkbenchWindowConfigurer configurer = getWindowConfigurer();        
    configurer.setPresentationFactory(new UnCloseableEditorPresentationFactory());    
  }

类UnCloseableEditorPresentationFactory扩展了WorkbenchPresentationFactory，你可以简单地覆盖方法

public StackPresentation creatEditorPresentation(Composite parent,IStackPresentationSite site)

as followings :
  DefaultTabFolder folder = new UnCloseableEditorFolder(parent, 
       editorTabPosition | SWT.BORDER,    
       site.supportsState(IStackPresentationSite.STATE_MINIMIZED),          
       site.supportsState(IStackPresentationSite.STATE_MAXIMIZED));
 // other code int this method is the same as the parent class

 then is the class UnCloseableFolder

 import org.eclipse.swt.SWT;  
 import org.eclipse.swt.widgets.Composite;  
 import org.eclipse.ui.internal.presentations.defaultpresentation.DefaultTabFolder;    
 import org.eclipse.ui.internal.presentations.util.AbstractTabItem;  
 public class UnCloseableEditorFolder extends DefaultTabFolder {   
     public UnCloseableEditorFolder(Composite parent, int flags,     
         boolean allowMin, boolean allowMax) {     
         super(parent, flags, allowMin, allowMax);   
     }  

  @SuppressWarnings("restriction")   
  public AbstractTabItem add(int index, int flags)   {     
      return super.add(index, flags ^ SWT.CLOSE);   
  }
 }

然后你可以删除EditorPart中的“X”按钮。它可以在我的机器上运行~~

这可以通过实施表示层来实现 - 请参阅http://wiki.eclipse.org/RCP_Custom_Look_and_Feel和http://e-rcp.blogspot.ca/2007/09/prevent-that-rcp-editor-is-closed.html。

删除或禁用RAP / RCP EditorPart上显示的“X”关闭按钮
