&lt;p&gt;
The &lt;b&gt;viewer&lt;/b&gt; element defines the configuration for a common viewer. The extension
may provide a custom popup menu id, override whether the viewer provides link with
editor support, provides a filter dialog, and/or provides an &quot;Available customizations&quot;
dialog. In addition, nested configuration elements give full control over the structure
and behavior of the popup context menu.
&lt;p&gt;
&lt;b&gt;viewerContentBinding&lt;/b&gt; binds defined content extensions (through the &lt;b&gt;navigatorContent&lt;/b&gt;
extension point) to viewers. &lt;b&gt;viewerContentBinding&lt;/b&gt; also binds a
&lt;b&gt;linkHelper&lt;/b&gt; extension point to a viewer.
Any content extension bound to a viewer is described as &lt;i&gt;visible&lt;/i&gt;. A
content service (&lt;code&gt;org.eclipse.ui.navigator.INavigatorContentService&lt;/code&gt;)
will not return any extensions which are not visible for
its viewer id.

Clients must define one or more &lt;b&gt;viewerContentBinding&lt;/b&gt; elements to describe which content extensions, common filters, and link helpers are &lt;i&gt;visible&lt;/i&gt; to the viewer. A content extension or common filter is &lt;i&gt;visible&lt;/i&gt; if the id of the content extension or common filter matches an &lt;b&gt;includes&lt;/b&gt; statement under a &lt;b&gt;viewerContentBinding&lt;/b&gt; and is not excluded by an &lt;b&gt;excludes&lt;/b&gt; statement. If a content extension or common filter is not &lt;i&gt;visible&lt;/i&gt; to a viewer, then the extension will never be asked for content by a content service for that viewer or be presented to the user in the available filters dialog.
&lt;br&gt;&lt;br&gt;
Clients may define an &lt;b&gt;includes&lt;/b&gt; element to select which extensions are &lt;i&gt;visible&lt;/i&gt; to the viewer, and similarly an &lt;b&gt;excludes&lt;/b&gt; element for extensions that should not be made &lt;i&gt;visible&lt;/i&gt; to the viewer. Clients may further define the extensions that should be explicitly queried for root elements (through ITreeContentProvider.getElements()) by the &quot;isRoot&quot; attribute. If one or more &lt;b&gt;contentExtension&lt;/b&gt; elements have &quot;isRoot&quot; set to true within the &lt;b&gt;includes&lt;/b&gt; statement, only those extensions will be queried for root elements. The &quot;isRoot&quot; attribute has no effect for exclusions.
&lt;br&gt;&lt;br&gt;
A viewer may have multiple viewerContentBindings defined, and their includes/excludes statements will be aggregated to produce the final behavior.

A popupMenu element may only be defined if the &quot;popupMenuId&quot; attribute of the
&lt;b&gt;viewer&lt;/b&gt; element is not specified.
&lt;br&gt;&lt;br&gt;
The &lt;b&gt;popupMenu&lt;/b&gt; element allows further customization of the context menu associated
with the viewer. For the options to be applied correctly, an instance of the viewer
must delegate to a &lt;code&gt;org.eclipse.ui.navigator.NavigatorActionService&lt;/code&gt;, which behaves
like a normal &lt;code&gt;org.eclipse.ui.ActionGroup&lt;/code&gt;. See the documentation for this API class
for more information on exploiting this functionality. For clients that use an
instance of &lt;code&gt;org.eclipse.ui.navigator.CommonNavigator&lt;/code&gt; do not need to do any extra work.
&lt;br&gt;&lt;br&gt;
A &lt;b&gt;popupMenu&lt;/b&gt; declares one or more &lt;b&gt;insertionPoints&lt;/b&gt; that will be used by contributors to
organize their contributions into a meaningful, more user-friendly, consistent list.
&lt;br&gt;
If clients only specify the &quot;popupMenuId&quot; attribute of the &lt;b&gt;viewer&lt;/b&gt; element, then the
set of &lt;b&gt;insertionPoints&lt;/b&gt; used by the context menu will default to the following list
in the given order:
&lt;br&gt;
&lt;pre&gt;
&quot;group.new&quot; separator=&quot;true&quot;
&quot;group.goto&quot;
&quot;group.open&quot; separator=&quot;true&quot;
&quot;group.openWith&quot;
&quot;group.show&quot; separator=&quot;true&quot;
&quot;group.edit&quot; separator=&quot;true&quot;
&quot;group.reorganize&quot;
&quot;group.port&quot;
&quot;group.generate&quot; separator=&quot;true&quot;
&quot;group.search&quot; separator=&quot;true&quot;
&quot;group.build&quot; separator=&quot;true&quot;
&quot;additions&quot; separator=&quot;true&quot;
&quot;group.properties&quot; separator=&quot;true&quot;
&lt;/pre&gt;
&lt;br&gt;&lt;br&gt;
Clients that wish to refer to these values programmatically may use the corresponding constants in &lt;code&gt;org.eclipse.ui.navigator.ICommonMenuConstants&lt;/code&gt;.
&lt;br&gt;&lt;br&gt;
Clients that wish to customize their menus are encouraged to start with this list and add or remove insertion points as necessary. Clients are also
encouraged to follow the pattern of beginning each group name with &quot;group.&quot;.
&lt;br&gt;&lt;br&gt;
If the &lt;b&gt;popupMenu&lt;/b&gt; element is specified and contains NO &lt;b&gt;insertionPoint&lt;/b&gt; children elements, then the context menu will have no published insertion points. Of course, programmatic clients are not restricted from adding their own insertion points as necessary. Clients defining viewers are encouraged to publish their insertion points for documentation purposes and clarity for downstream extensions to their viewers/navigators, or to explicitly document which insertion points are considered API and which are considered internal.

The following example configures the popup menu id for a viewer.
&lt;p&gt;
&lt;pre&gt;
&lt;extension
point=&quot;org.eclipse.ui.navigator.viewer&quot;&gt;
&lt;viewer
id=&quot;org.eclipse.testViewer&quot;
popupMenuId=&quot;org.eclipse.testViewer#PopupMenu&quot;/&gt;
&lt;/extension&gt;
&lt;/pre&gt;
&lt;/p&gt;
&lt;p&gt;
Since the &lt;b&gt;popupMenu&lt;/b&gt; child element of viewer is not used in the above example, the default set of
&lt;b&gt;insertionPoints&lt;/b&gt; will be used. This set is defined as follows. See the documentation for
the &lt;b&gt;popupMenu&lt;/b&gt; element for more information.
&lt;p&gt;
&lt;pre&gt;
&quot;group.new&quot; separator=&quot;true&quot;
&quot;group.goto&quot;
&quot;group.open&quot; separator=&quot;true&quot;
&quot;group.openWith&quot;
&quot;group.show&quot; separator=&quot;true&quot;
&quot;group.edit&quot; separator=&quot;true&quot;
&quot;group.reorganize&quot;
&quot;group.port&quot;
&quot;group.generate&quot; separator=&quot;true&quot;
&quot;group.search&quot; separator=&quot;true&quot;
&quot;group.build&quot; separator=&quot;true&quot;
&quot;additions&quot; separator=&quot;true&quot;
&quot;group.properties&quot; separator=&quot;true&quot;
&lt;/pre&gt;
&lt;/p&gt;
&lt;p&gt;
The following example demonstrates a viewer configuration which declares custom
&lt;b&gt;popupMenu/insertionPoints&lt;/b&gt;, but restricts object and viewer contributions
with the &quot;allowsPlatformContributions&quot; attribute. Clients may only contribute
to the defined menu via &lt;code&gt;org.eclipse.ui.navigator.CommonActionProvider&lt;/code&gt;s declared
for the viewer (either top-level or associated with content extensions).
&lt;p&gt;
Note that the &quot;popupMenuId&quot; attribute is not concurrently specified with the
&lt;b&gt;popupMenu&lt;/b&gt; element. Only one or the other, but not both, is a valid configuration.
&lt;p&gt;
&lt;pre&gt;
&lt;extension
point=&quot;org.eclipse.ui.navigator.viewer&quot;&gt;
&lt;viewer
viewerId=&quot;org.eclipse.ui.navigator.resourceContent&quot;&gt;
&lt;popupMenu
allowsPlatformContributions=&quot;false&quot;
id=&quot;org.eclipse.ui.navigator.resourceContent#PopupMenu&quot;&gt;
&lt;insertionPoint name=&quot;group.new&quot;/&gt;
&lt;insertionPoint
name=&quot;group.open&quot;
separator=&quot;true&quot;/&gt;
&lt;insertionPoint name=&quot;group.openWith&quot;/&gt;
&lt;insertionPoint
name=&quot;group.port&quot;
separator=&quot;true&quot;/&gt;
&lt;insertionPoint
name=&quot;additions&quot;
separator=&quot;true&quot;/&gt;
&lt;insertionPoint
name=&quot;group.properties&quot;
separator=&quot;true&quot;/&gt;
&lt;/popupMenu&gt;
&lt;/viewer&gt;
&lt;viewerContentBinding
viewerId=&quot;org.eclipse.ui.navigator.resourceContent&quot;&gt;
&lt;includes&gt;
&lt;contentExtension pattern=&quot;org.eclipse.ui.navigator.resourceContent&quot; /&gt;
&lt;/includes&gt;
&lt;/viewerContentBinding&gt;
&lt;/extension&gt;
&lt;/pre&gt;
&lt;/p&gt;
&lt;p&gt;
The following example declares that one content extension (id: &quot;org.eclipse.ui.navigator.resourceContent&quot;) is bound to a viewer matching the id &quot;org.eclipse.ui.navigator.resourceContent&quot;. (In this example the content extension and viewer ids match, but this is not required.)
&lt;p&gt;
&lt;pre&gt;
&lt;extension
point=&quot;org.eclipse.ui.navigator.viewer&quot;&gt;
&lt;viewerContentBinding
viewerId=&quot;org.eclipse.ui.navigator.resourceContent&quot;&gt;
&lt;includes&gt;
&lt;contentExtension pattern=&quot;org.eclipse.ui.navigator.resourceContent&quot; /&gt;
&lt;/includes&gt;
&lt;/viewerContentBinding&gt;
&lt;/extension&gt;
&lt;/pre&gt;
&lt;/p&gt;
&lt;p&gt;
The following example declares a &lt;b&gt;viewerActionBinding&lt;/b&gt; for all &lt;b&gt;actionProvider&lt;/b&gt;s (not
nested under a &lt;b&gt;navigatorContent&lt;/b&gt; extension) that match the regular expression
&quot;org.acme.actions.*&quot; but not &quot;org.acme.actions.tests.*&quot;. This expression
will make any &lt;b&gt;actionProvider&lt;/b&gt; whose id begins with &quot;org.acme.actions.&quot; but not &quot;org.acme.actions.tests.&quot; &lt;i&gt;visible&lt;/i&gt; to the viewer with the id &quot;org.acme.viewer&quot;.
Of course, the &lt;b&gt;viewerActionBindings&lt;/b&gt; only apply to &lt;b&gt;actionProvider&lt;/b&gt; elements that
are not nested under a &lt;b&gt;navigatorContent&lt;/b&gt; element. The &lt;i&gt;visibility&lt;/i&gt; of nested
&lt;b&gt;actionProvider&lt;/b&gt; elements is controlled by &lt;b&gt;viewerContentBindings&lt;/b&gt; for the enclosing
&lt;b&gt;navigatorContent&lt;/b&gt; element.
&lt;p&gt;
&lt;pre&gt;
&lt;extension
point=&quot;org.eclipse.ui.navigator.viewer&quot;&gt;
&lt;viewerActionBinding
viewerId=&quot;org.acme.viewer&quot;&gt;
&lt;includes&gt;
&lt;actionExtension pattern=&quot;org.acme.actions.*&quot; /&gt;
&lt;/includes&gt;
&lt;excludes&gt;
&lt;actionExtension pattern=&quot;org.acme.actions.tests.*&quot; /&gt;
&lt;/excludes&gt;
&lt;/viewerActionBinding&gt;
&lt;/extension&gt;
&lt;/pre&gt;
&lt;/p&gt;
&lt;p&gt;
The following example makes any actionProvider with no &quot;id&quot; attribute &lt;i&gt;visible&lt;/i&gt;
to the viewer &quot;org.acme.viewer&quot;. The &lt;b&gt;actionProvider&lt;/b&gt;s with no &quot;id&quot; attribute
have a default id of &quot;org.eclipse.ui.navigator.actionProvider.X&quot;. Of course,
the &lt;b&gt;viewerActionBindings&lt;/b&gt; only apply to &lt;b&gt;actionProvider&lt;/b&gt; elements that
are not nested under a &lt;b&gt;navigatorContent&lt;/b&gt; element. The &lt;i&gt;visibility&lt;/i&gt; of nested
&lt;b&gt;actionProvider&lt;/b&gt; elements is controlled by &lt;b&gt;viewerContentBinding&lt;/b&gt;s for the enclosing
&lt;b&gt;navigatorContent&lt;/b&gt; element.
&lt;p&gt;
&lt;pre&gt;
&lt;extension
point=&quot;org.eclipse.ui.navigator.viewer&quot;&gt;
&lt;viewerActionBinding
viewerId=&quot;org.acme.viewer&quot;&gt;
&lt;includes&gt;
&lt;actionExtension pattern=&quot;org.eclipse.ui.navigator.actionProvider.*&quot; /&gt;
&lt;/includes&gt;
&lt;/viewerActionBinding&gt;
&lt;/extension&gt;
&lt;/pre&gt;
&lt;/p&gt;
&lt;p&gt;
The following example demonstrates the standard properties available to the viewer.
&lt;/p&gt;
&lt;p&gt;
&lt;pre&gt;
&lt;extension
point=&quot;org.eclipse.ui.navigator.viewer&quot;&gt;
&lt;viewer
popupMenuId=&quot;org.eclipse.ui.tests.navigator.TestView#PopupMenu&quot;
viewerId=&quot;org.eclipse.ui.tests.navigator.TestView&quot;&gt;
&lt;options&gt;
&lt;!-- Hide the &quot;Available Extensions&quot; tab in the &quot;Available Customizations&quot;
dialog (available from the &quot;Filters&quot; action --&gt;
&lt;property
name=&quot;org.eclipse.ui.navigator.hideAvailableExtensionsTab&quot;
value=&quot;true&quot;/&gt;
&lt;!-- Hide the &quot;Available Customizations&quot; dialog completely. This includes hiding the
filters and the available content extensions. --&gt;
&lt;property
name=&quot;org.eclipse.ui.navigator.hideAvailableCustomizationsDialog&quot;
value=&quot;true&quot;/&gt;
&lt;!-- Hide the &quot;Link with Editor&quot; action from the toolbar of the viewer --&gt;
&lt;property
name=&quot;org.eclipse.ui.navigator.hideLinkWithEditorAction&quot;
value=&quot;true&quot;/&gt;
&lt;!-- Hide the &quot;Collapse All&quot; action from the toolbar of the viewer --&gt;
&lt;property
name=&quot;org.eclipse.ui.navigator.hideCollapseAllAction&quot;
value=&quot;true&quot;/&gt;
&lt;/options&gt;
&lt;/viewer&gt;
&lt;/extension&gt;
&lt;/pre&gt;
