EShellViewClass contains a number of important settings for subclasses.

GObjectClass `parent_class`; | The parent class structure.
const gchar *`label`; | The initial value for the switcher action's "label" property. See `e_shell_view_get_action()`.
const gchar *`icon_name`; | The initial value for the switcher action's "icon-name" property. See `e_shell_view_get_action()`.
const gchar *`ui_definition`; | Base name of the UI definintion file to add when the shell view is activated.
const gchar *`ui_manager_id`; | The GtkUIManager ID for EPluginUI. Plugins should use to this ID in their "eplug" files to add menu and toolbar items to the shell view.
GType `search_context_type`; | GType of the search context, which should be an instance of ERuleContextClass or a custom subclass.
ERuleContext *`search_context`; | A unique `search_context_type` instance is created automatically for each subclass and shared across all instances of that subclass.
const gchar *`search_options`; | Widget path in the UI definition to the search options popup menu. The menu gets shown when the user clicks the "find" icon in the search entry.
const gchar *`search_rules`; | Base name of the XML file containing predefined search rules for this shell view. The XML files are usually named something like <filename> <emphasis>view</emphasis>types.xml</filename>.
GalViewCollection *`view_collection`; | A unique GalViewCollection instance is created for each subclass and shared across all instances of that subclass. That much is done automatically for subclasses, but subclasses are still responsible for adding the appropriate GalView factories to the view collection.
EShellBackend *`shell_backend`; | The corresponding EShellBackend for the shell view.
`new_shell_content` () | Factory method for the shell view's EShellContent. See `e_shell_view_get_shell_content()`.
`new_shell_sidebar` () | Factory method for the shell view's EShellSidebar. See `e_shell_view_get_shell_sidebar()`.
`new_shell_taskbar` () | Factory method for the shell view's EShellTaskbar. See `e_shell_view_get_shell_taskbar()`.
`new_shell_searchbar` () | Factory method for the shell view's EShellSearchbar. See `e_shell_view_get_searchbar()`.
`construct_searchbar` () | Class method to create, configure and pack a search bar widget. The search bar differs in normal shell mode versus "express" mode.
`get_search_name` () | Class method to obtain a suitable name for the current search criteria. Subclasses should rarely need to override the default behavior.
`toggled` () | Class method for the "toggled" signal. Subclasses should rarely need to override the default behavior.
`clear_search` () | Class method for the "clear-search" signal. The default method sets the "search-rule" to `NULL` and then emits the "execute-search" signal.
`custom_search` () | Class method for the "custom-search" signal. This is emitted prior to executing an advanced or saved search. The default method sets the "search-rule" property and then emits the "execute-search" signal.
`execute_search` () | Class method for the "execute-search" signal. There is no default behavior; subclasses should override this.
`update_actions` () | Class method for the "update-actions" signal. There is no default behavior; subclasses should override this.

### e_shell_view_get_name ()

    const gchar *       e_shell_view_get_name               (EShellView *shell_view);

Returns the view name for `shell_view`, which is also the name of the corresponding EShellBackend (see the <structfield>name</structfield> field in EShellBackendInfo).

`shell_view` : | an EShellView
Returns : | the view name for `shell_view`

### e_shell_view_get_action ()

    GtkAction *         e_shell_view_get_action             (EShellView *shell_view);

Returns the switcher action for `shell_view`.

An EShellWindow creates a GtkRadioAction for each registered subclass of EShellView. This action gets passed to the EShellSwitcher, which displays a button that proxies the action. The icon at the top of the sidebar also proxies the action. When `shell_view` is active, the action's icon becomes the EShellWindow icon.

`shell_view` : | an EShellView
Returns : | the switcher action for `shell_view`

### e_shell_view_get_title ()

    const gchar *       e_shell_view_get_title              (EShellView *shell_view);

Returns the title for `shell_view`. When `shell_view` is active, the shell view's title becomes the EShellWindow title.

`shell_view` : | an EShellView
Returns : | the title for `shell_view`

### e_shell_view_set_title ()

    void                e_shell_view_set_title              (EShellView *shell_view,
                                                             const gchar *title);

Sets the title for `shell_view`. When `shell_view` is active, the shell view's title becomes the EShellWindow title.

`title` : | a title for `shell_view`

### e_shell_view_get_view_id ()

    const gchar *       e_shell_view_get_view_id            (EShellView *shell_view);

Returns the ID of the currently selected GalView.

EShellView subclasses are responsible for keeping this property in sync with their GalViewInstance. EShellView itself just provides a place to store the view ID, and emits a "notify" signal when the property changes.

`shell_view` : | an EShellView
Returns : | the ID of the current GalView

### e_shell_view_set_view_id ()

    void                e_shell_view_set_view_id            (EShellView *shell_view,

`view_id` : | a GalView ID

### e_shell_view_new_view_instance ()

    GalViewInstance *   e_shell_view_new_view_instance      (EShellView *shell_view,
                                                             const gchar *instance_id);

Convenience function creates a new GalViewInstance from the GalViewCollection in `shell_view`'s EShellViewClass.

`shell_view` : | an EShellView
Returns : | a GalViewInstance, or `NULL`

### e_shell_view_set_view_instance ()

    void                e_shell_view_set_view_instance      (EShellView *shell_view,

    gboolean            e_shell_view_is_active              (EShellView *shell_view);

Returns `TRUE` if `shell_view` is active. That is, if it's currently visible in its EShellWindow. An EShellWindow can only display one shell view at a time.

Technically this just checks the "active" property of the shell view's switcher action. See `e_shell_view_get_action()`.

`shell_view` : | an EShellView
Returns : | `TRUE` if `shell_view` is active

### e_shell_view_get_page_num ()

`shell_view` : | an EShellView
Returns : | the notebook page number for `shell_view`

### e_shell_view_set_page_num ()

    void                e_shell_view_set_page_num           (EShellView *shell_view,

Returns : | the searchbar widget for `shell_view`

### e_shell_view_get_search_name ()

    gchar *             e_shell_view_get_search_name        (EShellView *shell_view);

Returns a newly-allocated string containing a suitable name for the current search criteria. This is used as the suggested name in the Save Search dialog. Free the returned string with `g_free()`.

`shell_view` : | an EShellView
Returns : | a name for the current search criteria

### e_shell_view_get_search_rule ()

    EFilterRule *       e_shell_view_get_search_rule        (EShellView *shell_view);

    void                e_shell_view_set_search_rule        (EShellView *shell_view,
                                                             EFilterRule *search_rule);

Sets the search criteria used to generate the current search results. Note that this will not trigger a search. `e_shell_view_execute_search()` must be called explicitly.

`shell_view` : | an EShellView
`search_rule` : | an EFilterRule

### e_shell_view_get_search_query ()

    gchar *             e_shell_view_get_search_query       (EShellView *shell_view);

Converts the "search-rule" property to a newly-allocated S-expression string. If the "search-rule" property is `NULL` the function returns `NULL`.

`shell_view` : | an EShellView
Returns : | an S-expression string, or `NULL`

### e_shell_view_get_size_group ()

    GtkSizeGroup *      e_shell_view_get_size_group         (EShellView *shell_view);

Returns a GtkSizeGroup that EShellContent and EShellSidebar use to keep the search bar and sidebar banner vertically aligned. The rest of the application should have no need for this.

Note, this is only available during EShellView construction.

`shell_view` : | an EShellView

    EShellContent *     e_shell_view_get_shell_content      (EShellView *shell_view);

Returns the EShellContent instance for `shell_view`.

By default, EShellView creates a plain EShellContent during initialization. But EShellView subclasses can override the <structfield>new_shell_content</structfield> factory method in EShellViewClass to create a custom EShellContent.

`shell_view` : | an EShellView
Returns : | the EShellContent instance for `shell_view`

### e_shell_view_get_shell_sidebar ()
