g_desktop_app_info_new_from_filename ()

GDesktopAppInfo *
g_desktop_app_info_new_from_filename (const char *filename);

Creates a new GDesktopAppInfo.

g_desktop_app_info_new_from_keyfile ()

GDesktopAppInfo *
g_desktop_app_info_new_from_keyfile (GKeyFile *key_file);

Creates a new GDesktopAppInfo.

Since: 2.18

g_desktop_app_info_new ()

GDesktopAppInfo *
g_desktop_app_info_new (const char *desktop_id);

Creates a new GDesktopAppInfo based on a desktop file id.

A desktop file id is the basename of the desktop file, including the .desktop extension. GIO is looking for a desktop file with this name in the applications subdirectories of the XDG data directories (i.e. the directories specified in the XDG_DATA_HOME and XDG_DATA_DIRS environment variables). GIO also supports the prefix-to-subdirectory mapping that is described in the Menu Spec (i.e. a desktop id of kde-foo.desktop will match /usr/share/applications/kde/foo.desktop).

g_desktop_app_info_get_filename ()

const char *
g_desktop_app_info_get_filename (GDesktopAppInfo *info);

When info was created from a known filename, return it. In some situations such as the GDesktopAppInfo returned from g_desktop_app_info_new_from_keyfile(), this function will return NULL.

Since: 2.24

g_desktop_app_info_get_is_hidden ()

gboolean
g_desktop_app_info_get_is_hidden (GDesktopAppInfo *info);

A desktop file is hidden if the Hidden key in it is set to True.

g_desktop_app_info_get_nodisplay ()

gboolean
g_desktop_app_info_get_nodisplay (GDesktopAppInfo *info);

Gets the value of the NoDisplay key, which helps determine if the application info should be shown in menus. See G_KEY_FILE_DESKTOP_KEY_NO_DISPLAY and g_app_info_should_show().

Since: 2.30

g_desktop_app_info_get_show_in ()

gboolean
g_desktop_app_info_get_show_in (GDesktopAppInfo *info,
                                const gchar *desktop_env);

Checks if the application info should be shown in menus that list available applications for a specific name of the desktop, based on the OnlyShowIn and NotShowIn keys.

desktop_env should typically be given as NULL, in which case the XDG_CURRENT_DESKTOP environment variable is consulted. If you want to override the default mechanism then you may specify desktop_env , but this is not recommended.

Note that g_app_info_should_show() for info will include this check (with NULL for desktop_env ) as well as additional checks.

Since: 2.30

Since: 2.34

g_desktop_app_info_set_desktop_env ()

void
g_desktop_app_info_set_desktop_env (const char *desktop_env);

Sets the name of the desktop that the application is running in. This is used by g_app_info_should_show() and g_desktop_app_info_get_show_in() to evaluate the OnlyShowIn and NotShowIn desktop entry fields.

Should be called only once; subsequent calls are ignored.

g_desktop_app_info_get_string ()

GDesktopAppLaunchCallback ()

void
(*GDesktopAppLaunchCallback) (GDesktopAppInfo *appinfo,
                              GPid pid,
                              gpointer user_data);

During invocation, g_desktop_app_info_launch_uris_as_manager() may create one or more child processes. This callback is invoked once for each, providing the process ID.

g_desktop_app_info_launch_uris_as_manager ()

gboolean
g_desktop_app_info_launch_uris_as_manager
                               (GDesktopAppInfo *appinfo,
                                GList *uris,
                                GAppLaunchContext *launch_context,
                                GSpawnFlags spawn_flags,
                                GSpawnChildSetupFunc user_setup,
                                gpointer user_setup_data,
                                GDesktopAppLaunchCallback pid_callback,
                                gpointer pid_callback_data,
                                GError **error);

This function performs the equivalent of g_app_info_launch_uris(), but is intended primarily for operating system components that launch applications. Ordinary applications should use g_app_info_launch_uris().

If the application is launched via GSpawn, then spawn_flags , user_setup and user_setup_data are used for the call to g_spawn_async(). Additionally, pid_callback (with pid_callback_data ) will be called to inform about the PID of the created process. See g_spawn_async_with_pipes() for information on certain parameter conditions that can enable an optimized posix_spawn() codepath to be used.

If application launching occurs via some other mechanism (eg: D-Bus activation) then spawn_flags , user_setup , user_setup_data , pid_callback and pid_callback_data are ignored.

g_desktop_app_info_launch_uris_as_manager_with_fds ()

gboolean
g_desktop_app_info_launch_uris_as_manager_with_fds
                               (GDesktopAppInfo *appinfo,
                                GList *uris,
                                GAppLaunchContext *launch_context,
                                GSpawnFlags spawn_flags,
                                GSpawnChildSetupFunc user_setup,
                                gpointer user_setup_data,
                                GDesktopAppLaunchCallback pid_callback,
                                gpointer pid_callback_data,
                                gint stdin_fd,
                                gint stdout_fd,
                                gint stderr_fd,
                                GError **error);

Equivalent to g_desktop_app_info_launch_uris_as_manager() but allows you to pass in file descriptors for the stdin, stdout and stderr streams of the launched process.

If application launching occurs via some non-spawn mechanism (e.g. D-Bus activation) then stdin_fd , stdout_fd and stderr_fd are ignored.

g_desktop_app_info_list_actions ()

const gchar * const *
g_desktop_app_info_list_actions (GDesktopAppInfo *info);

Returns the list of "additional application actions" supported on the desktop file, as per the desktop file specification.

As per the specification, this is the list of actions that are explicitly listed in the "Actions" key of the [Desktop Entry] group.

Since: 2.38

g_desktop_app_info_get_action_name ()

gchar *
g_desktop_app_info_get_action_name (GDesktopAppInfo *info,
                                    const gchar *action_name);

Gets the user-visible display name of the "additional application action" specified by action_name .

This corresponds to the "Name" key within the keyfile group for the action.

Since: 2.38

g_desktop_app_info_launch_action ()

void
g_desktop_app_info_launch_action (GDesktopAppInfo *info,
                                  const gchar *action_name,
                                  GAppLaunchContext *launch_context);

Activates the named application action.

You may only call this function on action names that were returned from g_desktop_app_info_list_actions().

Note that if the main entry of the desktop file indicates that the application supports startup notification, and launch_context is non-NULL, then startup notification will be used when activating the action (and as such, invocation of the action on the receiving side must signal the end of startup notification when it is completed). This is the expected behaviour of applications declaring additional actions, as per the desktop file specification.

As with g_app_info_launch() there is no way to detect failures that occur while using this function.

Since: 2.38

g_desktop_app_info_search ()

gchar ***
g_desktop_app_info_search (const gchar *search_string);

Searches desktop files for ones that match search_string .

The return value is an array of strvs. Each strv contains a list of applications that matched search_string with an equal score. The outer list is sorted by score so that the first strv contains the best-matching applications, and so on. The algorithm for determining matches is undefined and may change at any time.

None of the search results are subjected to the normal validation checks performed by g_desktop_app_info_new() (for example, checking that the executable referenced by a result exists), and so it is possible for g_desktop_app_info_new() to return NULL when passed an app ID returned by this function. It is expected that calling code will do this when subsequently creating a GDesktopAppInfo for each result.

g_desktop_app_info_get_implementations ()

GList *
g_desktop_app_info_get_implementations
                               (const gchar *interface);

Gets all applications that implement interface .

An application implements an interface if that interface is listed in the Implements= line of the desktop file of the application.

Since: 2.42
