## 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 ()

    GalViewInstance *
    e_shell_view_new_view_instance (EShellView *shell_view,

EShellView subclasses are responsible for creating and configuring a GalViewInstance and handing it off so the `shell_view` can monitor it and perform common actions on it.

#### 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,

Clears the current search. See `e_shell_view_clear_search()` for details.

#### Parameters

shell_view | the EShellView which emitted the signal |
user_data | user data set when the signal handler was connected. |

Flags: Run Last

### The `“custom-search”` signal

    void
    user_function (EShellView  *shell_view,
                   EFilterRule *custom_rule,
                   gpointer     user_data)

Emitted when an advanced or saved search is about to be executed. See `e_shell_view_custom_search()` for details.

#### Parameters

shell_view | the EShellView which emitted the signal |
custom_rule | criteria for the custom search |
user_data | user data set when the signal handler was connected. |

Flags: Run Last

### The `“execute-search”` signal

    void
    user_function (EShellView *shell_view,
                   gpointer    user_data)

EShellView subclasses should override the <structfield>execute_search</structfield> method in EShellViewClass to execute the current search conditions.

#### Parameters

shell_view | the EShellView which emitted the signal |
user_data | user data set when the signal handler was connected. |

Flags: Run First

### The `“toggled”` signal

    void
    user_function (EShellView *shell_view,
                   gpointer    user_data)

Emitted when `shell_view` is activated or deactivated. Use `e_shell_view_is_active()` to find out which event has occurred. The shell view being deactivated is always notified before the shell view being activated.

By default, EShellView adds the UI definition file given in the <structfield>ui_definition</structfield> field of EShellViewClass on activation, and removes the UI definition on deactivation.

#### Parameters

shell_view | the EShellView which emitted the signal |
user_data | user data set when the signal handler was connected. |

Flags: Run First

### The `“update-actions”` signal

    void
    user_function (EShellView *shell_view,
                   gpointer    user_data)

EShellView subclasses should override the <structfield>update_actions</structfield> method in EShellViewClass to update sensitivities, labels, or any other aspect of the GtkAction<!-- -->s they have registered.

Plugins can also connect to this signal to be notified when to update their own GtkAction<!-- -->s.

#### Parameters

shell_view | the EShellView which emitted the signal |
user_data | user data set when the signal handler was connected. |

Flags: Run First
