本文介绍如何在Eclipse的Project Explorer中实现'Link with editor'功能，通过扩展plug-in.xml文件来支持特定类型的文件与编辑器之间的链接。具体包括配置'org.eclipse.ui.navigator.linkHelper'和'org.eclipse.ui.navigator.viewer'扩展点。

为eidtor在ProjectExplorer中支持'Link with editor' 功能，需要在plug.xml中扩展 'org.eclipse.ui.navigator.linkHelper' 和 'org.eclipse.ui.navigator.viewer'

  <extension
         point="org.eclipse.ui.navigator.linkHelper">
      <linkHelper
            class="org.myym.MyLinkHelper"
            id="org.myym.mylinkhelper">
         <editorInputEnablement></editorInputEnablement>
         <selectionEnablement>
            <instanceof
                  value="org.eclipse.core.resources.IFile">
            </instanceof>
         </selectionEnablement>
      </linkHelper>
   </extension>
   <extension
         point="org.eclipse.ui.navigator.viewer">
      <viewerContentBinding
            viewerId="org.eclipse.ui.navigator.ProjectExplorer">
         <includes>
            <contentExtension
                  pattern="org.myym.mylinkhelper">
            </contentExtension>
         </includes>
      </viewerContentBinding>
   </extension>

MyLinkHelper.java

/**
 * Link Helper for editors.
 */
public class MyLinkHelper implements ILinkHelper {

    /**
     * Default Constructor. 
     */
    public MyLinkHelper() {
    }

	public void activateEditor(IWorkbenchPage aPage, IStructuredSelection aSelection) {
    }

    public IStructuredSelection findSelection(IEditorInput anInput) {
        if (anInput instanceof MyClass) //check the IEditorInput whether are interested 
	    IFile file = getFile(MyClass); //create method 'getFile' to get the IFile refer to this input
            if (file != null) {
                return new StructuredSelection(file);
            }
        }
        return StructuredSelection.EMPTY;
    }
}
