Struct gio::DesktopAppInfo

source ·
pub struct DesktopAppInfo { /* private fields */ }
Available on non-Windows and non-macOS only.
Expand description

GDesktopAppInfo is an implementation of AppInfo based on desktop files.

Note that <gio/gdesktopappinfo.h> belongs to the UNIX-specific GIO interfaces, thus you have to use the gio-unix-2.0.pc pkg-config file when using it.

§Properties

§filename

The origin filename of this #GDesktopAppInfo

Readable | Writeable | Construct Only

§Implements

Implementations§

source§

impl DesktopAppInfo

source

pub fn search(search_string: &str) -> Vec<Vec<GString>>

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 None 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.

§search_string

the search string to use

§Returns

a list of strvs. Free each item with g_strfreev() and free the outer list with g_free().

source§

impl DesktopAppInfo

source

pub fn new(desktop_id: &str) -> Option<DesktopAppInfo>

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).

§desktop_id

the desktop file id

§Returns

a new #GDesktopAppInfo, or None if no desktop file with that id exists.

source

pub fn from_filename(filename: impl AsRef<Path>) -> Option<DesktopAppInfo>

Creates a new #GDesktopAppInfo.

§filename

the path of a desktop file, in the GLib filename encoding

§Returns

a new #GDesktopAppInfo or None on error.

source

pub fn from_keyfile(key_file: &KeyFile) -> Option<DesktopAppInfo>

Creates a new #GDesktopAppInfo.

§key_file

an opened #GKeyFile

§Returns

a new #GDesktopAppInfo or None on error.

source

pub fn action_name(&self, action_name: &str) -> GString

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.

§action_name

the name of the action as from g_desktop_app_info_list_actions()

§Returns

the locale-specific action name

source

pub fn boolean(&self, key: &str) -> bool

Looks up a boolean value in the keyfile backing @self.

The @key is looked up in the “Desktop Entry” group.

§key

the key to look up

§Returns

the boolean value, or false if the key is not found

source

pub fn categories(&self) -> Option<GString>

Gets the categories from the desktop file.

§Returns

The unparsed Categories key from the desktop file; i.e. no attempt is made to split it by ‘;’ or validate it.

source

pub fn filename(&self) -> Option<PathBuf>

When @self 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 None.

§Returns

The full path to the file for @self, or None if not known.

source

pub fn generic_name(&self) -> Option<GString>

Gets the generic name from the desktop file.

§Returns

The value of the GenericName key

source

pub fn is_hidden(&self) -> bool

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

§Returns

true if hidden, false otherwise.

source

pub fn keywords(&self) -> Vec<GString>

Gets the keywords from the desktop file.

§Returns

The value of the Keywords key

source

pub fn locale_string(&self, key: &str) -> Option<GString>

Looks up a localized string value in the keyfile backing @self translated to the current locale.

The @key is looked up in the “Desktop Entry” group.

§key

the key to look up

§Returns

a newly allocated string, or None if the key is not found

source

pub fn is_nodisplay(&self) -> bool

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().

§Returns

The value of the NoDisplay key

source

pub fn shows_in(&self, desktop_env: Option<&str>) -> bool

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 None, 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 @self will include this check (with None for @desktop_env) as well as additional checks.

§desktop_env

a string specifying a desktop name

§Returns

true if the @self should be shown in @desktop_env according to the OnlyShowIn and NotShowIn keys, false otherwise.

source

pub fn startup_wm_class(&self) -> Option<GString>

Retrieves the StartupWMClass field from @self. This represents the WM_CLASS property of the main window of the application, if launched through @self.

§Returns

the startup WM class, or None if none is set in the desktop file.

source

pub fn string(&self, key: &str) -> Option<GString>

Looks up a string value in the keyfile backing @self.

The @key is looked up in the “Desktop Entry” group.

§key

the key to look up

§Returns

a newly allocated string, or None if the key is not found

source

pub fn string_list(&self, key: &str) -> Vec<GString>

Available on crate feature v2_60 only.

Looks up a string list value in the keyfile backing @self.

The @key is looked up in the “Desktop Entry” group.

§key

the key to look up

§Returns

a None-terminated string array or None if the specified key cannot be found. The array should be freed with g_strfreev().

source

pub fn has_key(&self, key: &str) -> bool

Returns whether @key exists in the “Desktop Entry” group of the keyfile backing @self.

§key

the key to look up

§Returns

true if the @key exists

source

pub fn launch_action( &self, action_name: &str, launch_context: Option<&impl IsA<AppLaunchContext>> )

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-None, 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.

§action_name

the name of the action as from g_desktop_app_info_list_actions()

§launch_context

a #GAppLaunchContext

source

pub fn launch_uris_as_manager( &self, uris: &[&str], launch_context: Option<&impl IsA<AppLaunchContext>>, spawn_flags: SpawnFlags, user_setup: Option<Box_<dyn FnOnce() + 'static>>, pid_callback: Option<&mut dyn FnMut(&DesktopAppInfo, Pid)> ) -> Result<(), 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.

§uris

List of URIs

§launch_context

a #GAppLaunchContext

§spawn_flags

#GSpawnFlags, used for each process

§user_setup

a #GSpawnChildSetupFunc, used once for each process.

§user_setup_data

User data for @user_setup

§pid_callback

Callback for child processes

§pid_callback_data

User data for @callback

§Returns

true on successful launch, false otherwise.

source

pub fn list_actions(&self) -> Vec<GString>

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.

§Returns

a list of strings, always non-None

source

pub fn implementations(interface: &str) -> Vec<DesktopAppInfo>

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.

§interface

the name of the interface

§Returns

a list of #GDesktopAppInfo objects.
