#### Functions

###### eog_application_get_instance

Returns a singleton instance of `EogApplication` currently running. If not running yet, it will create one.

#### Instance methods

###### eog_application_close_all_windows

No description available.

###### eog_application_open_file_list

Opens a list of files in a `EogWindow`. If an `EogWindow` displaying the first image in the list is already open, this will be used. Otherwise, an empty `EogWindow` is used, either already existing or newly created. If the EOG_STARTUP_SINGLE_WINDOW flag is set, the files are opened in the first `EogWindow` and no new one is opened.

###### eog_application_open_uri_list

Opens a list of images, from a list of URIs. See `eog_application_open_file_list()` for details.

###### eog_application_open_uris

Opens a list of images, from a list of URI strings. See `eog_application_open_file_list()` for details.

###### eog_application_open_window

Opens and presents an empty `EogWindow` to the user. If there is an empty window already open, this will be used. Otherwise, a new one will be instantiated.

#### Signals

##### Signals inherited from GtkApplication (3)

###### GtkApplication::query-end

Emitted when the session manager is about to end the session, only if `GtkApplication::register-session` is `TRUE`. Applications can connect to this signal and call `gtk_application_inhibit()` with `GTK_APPLICATION_INHIBIT_LOGOUT` to delay the end of the session until state has been saved.

since: 3.24.8

Emitted when a `GtkWindow` is added to `application` through gtk_application_add_window().

since: 3.2

###### GtkApplication::window-removed

Emitted when a `GtkWindow` is removed from `application`, either as a side-effect of being destroyed or explicitly through gtk_application_remove_window().

since: 3.2

##### Signals inherited from GApplication (7)

###### GApplication::activate

The ::activate signal is emitted on the primary instance when an activation occurs. See g_application_activate().

###### GApplication::command-line

The ::command-line signal is emitted on the primary instance when a commandline is not handled locally. See `g_application_run()` and the `GApplicationCommandLine` documentation for more information.

###### GApplication::handle-local-options

The ::handle-local-options signal is emitted on the local instance after the parsing of the commandline options has occurred.

since: 2.40

###### GApplication::name-lost

The ::name-lost signal is emitted only on the registered primary instance when a new instance has taken over. This can only happen if the application is using the `G_APPLICATION_ALLOW_REPLACEMENT` flag.

since: 2.60

###### GApplication::open

The ::open signal is emitted on the primary instance when there are files to open. See `g_application_open()` for more information.

###### GApplication::shutdown

The ::shutdown signal is emitted only on the registered primary instance immediately after the main loop terminates.

###### GApplication::startup

The ::startup signal is emitted on the primary instance immediately after registration. See g_application_register().

##### Signals inherited from GObject (1)

###### GObject::notify

Signals that the state of the named action has changed.
