         This extension point is used to add actions to the pulldown menu and toolbar for views registered by other plug-ins. Each view has a local pulldown menu normally activated 
by clicking on the top right triangle button. Other plug-ins can contribute submenus and actions to this menu. Plug-ins may also contribute actions to a view toolbar. View owners are first given a chance to populate these areas. Optional additions by other plug-ins are appended.

         The following is an example of a view action extension:
&lt;p&gt;
&lt;pre&gt;
   &lt;extension point=&quot;org.eclipse.ui.viewActions&quot;&gt; 
      &lt;viewContribution 
         id=&quot;com.xyz.xyzViewC1&quot; 
         targetID=&quot;org.eclipse.ui.views.navigator.ResourceNavigator&quot;&gt; 
         &lt;menu
            id=&quot;com.xyz.xyzMenu&quot; 
            label=&quot;XYZ Menu&quot; 
            path=&quot;additions&quot;&gt; 
            &lt;separator name=&quot;group1&quot;/&gt; 
         &lt;/menu&gt; 
         &lt;action
            id=&quot;com.xyz.runXYZ&quot; 
            label=&quot;&amp;amp;Run XYZ Tool&quot; 
            menubarPath=&quot;com.xyz.xyzMenu/group1&quot; 
            toolbarPath=&quot;Normal/additions&quot;
            style=&quot;toggle&quot;
            state=&quot;true&quot; 
            icon=&quot;icons/runXYZ.gif&quot; 
            tooltip=&quot;Run XYZ Tool&quot; 
            helpContextId=&quot;com.xyz.run_action_context&quot; 
            class=&quot;com.xyz.actions.RunXYZ&quot;&gt; 
            &lt;selection class=&quot;org.eclipse.core.resources.IFile&quot; name=&quot;*.java&quot;/&gt; 
         &lt;/action&gt; 
     &lt;/viewContribution&gt; 
   &lt;/extension&gt; 
&lt;/pre&gt;
&lt;/p&gt;
&lt;p&gt;
In the example above, the specified action will only enable for a single selection (&lt;samp&gt;enablesFor&lt;/samp&gt; attribute). In addition, the object in the selection must be a Java file resource.
&lt;/p&gt;
&lt;p&gt;
The following is an other example of a view action extension: 
&lt;/p&gt;
&lt;p&gt;
&lt;pre&gt;
   &lt;extension point=&quot;org.eclipse.ui.viewActions&quot;&gt; 
      &lt;viewContribution 
         id=&quot;com.xyz.xyzViewC1&quot; 
         targetID=&quot;org.eclipse.ui.views.navigator.ResourceNavigator&quot;&gt; 
         &lt;menu
            id=&quot;com.xyz.xyzMenu&quot; 
            label=&quot;XYZ Menu&quot; 
            path=&quot;additions&quot;&gt; 
            &lt;separator name=&quot;group1&quot;/&gt; 
         &lt;/menu&gt; 
         &lt;action 
            id=&quot;com.xyz.runXYZ2&quot; 
            label=&quot;&amp;amp;Run XYZ2 Tool&quot; 
            menubarPath=&quot;com.xyz.xyzMenu/group1&quot;
            style=&quot;push&quot;
            icon=&quot;icons/runXYZ2.gif&quot; 
            tooltip=&quot;Run XYZ2 Tool&quot; 
            helpContextId=&quot;com.xyz.run_action_context2&quot; 
            class=&quot;com.xyz.actions.RunXYZ2&quot;&gt; 
            &lt;enablement&gt;
               &lt;and&gt;
                  &lt;objectClass name=&quot;org.eclipse.core.resources.IFile&quot;/&gt;
                  &lt;not&gt;
                     &lt;objectState name=&quot;extension&quot; value=&quot;java&quot;/&gt;
                  &lt;/not&gt;
               &lt;/and&gt;
            &lt;/enablement&gt;
         &lt;/action&gt; 
      &lt;/editorContribution&gt; 
   &lt;/extension&gt; 
&lt;/pre&gt;
&lt;/p&gt;
&lt;p&gt;
In the example above, the specified action will appear as a menu item. The action is enabled if the selection contains no Java file resources.
      </documentation>
   </annotation>

   <annotation>
      <appInfo>
         <meta.section type="apiInfo"/>
      </appInfo>
      <documentation>
         The value of the &lt;samp&gt;class&lt;/samp&gt; attribute must be a fully qualified name of a Java class that implements &lt;samp&gt;org.eclipse.ui.IViewActionDelegate&lt;/samp&gt;. This class is loaded as late as possible to avoid loading the entire plug-in before it is really needed.
&lt;p&gt;
The interface &lt;samp&gt;org.eclipse.ui.IViewActionDelegate&lt;/samp&gt; extends &lt;samp&gt;org.eclipse.ui.IActionDelegate&lt;/samp&gt; and adds an additional method that allows the 
delegate to initialize with the view instance it is contributing into.
&lt;/p&gt;
&lt;p&gt;
This extension point can be used to contribute actions into menus previously created by the target view. Omitting the menu path attribute will result in adding the new menu or action at the end of the pulldown menu.
&lt;/p&gt;
&lt;p&gt;
The enablement criteria for an action extension is initially defined by &lt;samp&gt;enablesFor&lt;/samp&gt;, and also either &lt;samp&gt;selection&lt;/samp&gt; or &lt;samp&gt;enablement&lt;/samp&gt;. However, once the action delegate has been instantiated, it may control the action enable state directly within its &lt;samp&gt;selectionChanged&lt;/samp&gt; method.
&lt;/p&gt;
&lt;p&gt;
Action and menu labels may contain special characters that encode mnemonics using the following rules:
&lt;ol&gt;
&lt;li&gt;
Mnemonics are specified using the ampersand (&apos;&amp;amp;&apos;) character in front
of a selected character in the translated text. Since ampersand is not
allowed in XML strings, use &lt;samp&gt;&amp;amp;amp;&lt;/samp&gt; character entity.&lt;/li&gt;
&lt;/ol&gt;
If two or more actions are contributed to a menu or toolbar by a single extension the actions will appear in the reverse order of how they are listed in the plugin.xml file. This behavior is admittedly unintuitive.  However, it was discovered after the  Eclipse Platform API was frozen.  Changing the behavior now would break every plug-in which relies upon the existing behavior.
&lt;p&gt;
The &lt;samp&gt;selection&lt;/samp&gt; and &lt;samp&gt;enablement&lt;/samp&gt; elements are mutually exclusive. The &lt;samp&gt;enablement&lt;/samp&gt; element can replace the &lt;samp&gt;selection&lt;/samp&gt; element using the sub-elements &lt;samp&gt;objectClass&lt;/samp&gt; and &lt;samp&gt;objectState&lt;/samp&gt;. For example, the following:
&lt;pre&gt;
 &lt;selection
  class=&quot;org.eclipse.core.resources.IFile&quot;
