Description

Functions

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).

Parameters

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.

Parameters

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.

Parameters

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.

Parameters

shell_view

an EShellView

 

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.

Parameters

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,

Selects the GalView whose ID is equal to view_id .

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.

Parameters

shell_view

an EShellView

 

view_id

a GalView ID

 

e_shell_view_new_view_instance ()

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

Parameters

shell_view

an EShellView

 

instance_id

a name for the GalViewInstance

 

Returns

a new GalViewInstance


e_shell_view_get_view_instance ()

GalViewInstance *
e_shell_view_get_view_instance (EShellView *shell_view);

Parameters

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,

Returns

TRUE if shell_view is active

Runs the func in a dedicated thread. Any error is propagated to UI. The cancellable passed into the func is a CamelOperation, thus the caller can overwrite progress and description message on it.

Parameters

shell_view

an EShellView instance

 

description

user-friendly description of the job, to be shown in UI

 

alert_ident

in case of an error, this alert identificator is used for EAlert construction

 

alert_arg_0

in case of an error, use this string as the first argument to the EAlert construction; the second argument is the actual error message; can be NULL, in which case only the error message is passed to the EAlert construction.

[allow-none]

func

function to be run in a dedicated thread

 

user_data

custom data passed into func ; can be NULL.

[allow-none]

free_user_data

function to be called on user_data , when the job is over; can be NULL.

[allow-none]

Returns

Newly created EActivity on success. The caller is responsible to g_object_unref() it when done with it.

Note: The free_user_data , if set, is called in the main thread.

Note: This function can be called only from the main thread.

EShellViewClass contains a number of important settings for subclasses.

Members

const gchar *label;

The initial value for the switcher action's “label” property. See e_shell_view_get_action().

 

const gchar *icon_name;

const gchar *ui_definition;

Base name of the UI definintion file to add when the shell view is activated.

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().

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.
