[news.eclipse.platform.swt] Re: Retarget or override Open, Save, Delete

["Rahul Kamdar" <rtkamdar@xxxxxxxxxxxxxxxxx>]

Hi Francis,

Thanks for the help that you extended. I worked on the following and used it 
successfully to override the Open action (this is registered as a 
Retargettable action already). However, for the editActions (copy, paste) I 
am unable to override the default action, since I need to register my 
actions as retargetting these default actions. How can I do that really?

The way I have added my actions (following instructions given on the CNF 
blog - scribbledideas.blogspot.com) is using actionProvider... following is 
roughly the code from the plugin.xml for reference (if it helps!)...

<extension
       id="com.sample.prjexpextn"
       name="sample Project"
       point="org.eclipse.ui.navigator.navigatorContent">
    <navigatorContent
          activeByDefault="true"
          contentProvider="com.sample.prjexpextn.cnf.VFileContentProvider"
          icon="/icons/designer_folder_tree_icon.gif"
          id="com.sample.xpd.projectExplorer.extension"
          labelProvider="com.sample.prjexpextn.cnf.VFileLabelProvider"
          name="Sample"
          priority="high">
<actionProvider
                  class="com.sample.prjexpextn.cnf.action.providers.EditActionProvider"
                  id="com.sample.prjexpexten.actionProvider.EditAction"
                  overrides="org.eclipse.ui.navigator.resources.EditActions">
               <enablement>
           <or>
            <and>
             <adapt type="org.eclipse.core.resources.IFile" />
             <test
              ...............
            </test>
            </and>
            <and>
             <adapt type="org.eclipse.core.resources.IFolder" />
             <test
              ...................
             </test>
            </and>
           </or>
          </enablement>
  </actionProvider>
</navigatorContent>
 </extension>

I believe in order to ensure that these actions RETARGET the original 
copy/paste, I have to define them as retargettable actions? CNF as of now 
has only one retargettable action 
org.eclipse.ui.navigator.ICommonActionConstants.OPEN. So similarly, how do I 
register other actions as retarget actions?

Thanks,
Rahul
