struct EShellView
struct EShellView;
Contains only private data that should be read and manipulated using the functions below.

EShellViewClass contains a number of important settings for subclasses.
The parent class structure. | |
The initial value for the switcher action's
"label" property. See
e_shell_view_get_action() . |
|
The initial value for the switcher action's
"icon-name" property. See
e_shell_view_get_action() . |
|
Base name of the UI definintion file to add when the shell view is activated. | |
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 of the search context, which should be an instance of ERuleContextClass or a custom subclass. | |
A unique search_context_type instance is created
automatically for each subclass and shared across
all instances of that subclass. |
|
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. | |
Base name of the XML file containing predefined
search rules for this shell view. The XML files
are usually named something like
viewtypes.xml . |
|
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 * |
The corresponding EShellBackend for the shell view. |
Factory method for the shell view's EShellContent.
See e_shell_view_get_shell_content() . |
|
Factory method for the shell view's EShellSidebar.
See e_shell_view_get_shell_sidebar() . |
|
Factory method for the shell view's EShellTaskbar.
See e_shell_view_get_shell_taskbar() . |
|
Class method for the "toggled" signal. Subclasses should rarely need to override the default behavior. | |
Class method for the "clear-search"
signal. The default method sets the
"search-rule" to NULL and then emits
the "execute-search" signal. |
|
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. | |
Class method for the "execute-search" signal. There is no default behavior; subclasses should override this. | |
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 name
field in EShellBackendInfo).
|
an EShellView |

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.

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
|
e_shell_view_set_title ()
void e_shell_view_set_title (EShellView *shell_view

a title for shell_view
|
e_shell_view_get_view_id ()
const gchar * e_shell_view_get_view_id (EShellView *shell_view
);

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.
|
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

visible in its EShellWindow. An EShellWindow can only display one
shell view at a time.

the shell view's switcher action. See e_shell_view_get_action()
.

an EShellView |
Returns : |
TRUE if shell_view is active |
e_shell_view_get_page_num ()
gint e_shell_view_get_page_num (EShellView *shell_view

e_shell_view_set_page_num ()
void e_shell_view_set_page_num (EShellView *shell_view

GtkNotebook page number for shell_view
. The rest of the application
must never call this because it could mess up shell view switching.

);
Emits the "update-actions" signal.
EShellView subclasses should implement the
update_actions
method in EShellViewClass
to update the various GtkActions based on the current
EShellSidebar and EShellContent selections. The
"update-actions" signal is typically emitted just before
showing a popup menu or just after the user selects an item in the
shell view.
Emission can be blocked by e_shell_view_block_update_actions()
.

the UI definition loaded into shell_view
's user interface
manager. The menu will be shown at the current mouse cursor position.

showing the menu to give shell_view
and any plugins that extend
shell_view
a chance to update the menu's actions.

The "custom-search"
signal
void user_function (EShellView *shell_view,
EFilterRule *custom_rule,
gpointer user_data) : Run Last
