Resource Change Plugin for eclipse

问题

I created an RCP application which detects resource change in its own view by extending CommonNavigator.

public abstract class NavigatorView extends CommonNavigator  implements
    IResourceChangeListener {
public void createPartControl(Composite parent) {
 super.createPartControl(parent);
 hookResourceChangeCommand(); // my resource tracking function.
 }
}

But now I need to create a plugin for this which detects resource change in project explorer in eclipse itself. I cannot create a view now and I need to detect already existing view. How should I do it ?

回答1:

Please completely remove the view that you created. You should not do anything in the UI, if you want to track resource changes, as resources are part of the workspace concept, and the workspace is generally headless (that is without UI).

Instead use the code below (taken from the resource change listener tutorial):

IWorkspace workspace = ResourcesPlugin.getWorkspace();
   IResourceChangeListener listener = new IResourceChangeListener() {
      public void resourceChanged(IResourceChangeEvent event) {
         System.out.println("Something changed!");
      }
   };
   workspace.addResourceChangeListener(listener);

   //... some time later one ...
   workspace.removeResourceChangeListener(listener);
