#GDesktopAppInfo is an implementation of #GAppInfo 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.

Index

Constructors

  • Parameters

    Returns 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).

    Parameters

    • desktopId: string

      the desktop file id

    Returns DesktopAppInfo

Properties

filename: string

The origin filename of this #GDesktopAppInfo

gTypeInstance: TypeInstance
name: string

Methods

  • addSupportsType(contentType: string): boolean
  • Adds a content type to the application information to indicate the application is capable of opening files with the given content type.

    Parameters

    • contentType: string

      a string.

    Returns boolean

  • Creates a binding between source_property on source and target_property on target.

    Whenever the source_property is changed the target_property is updated using the same value. For instance:

      g_object_bind_property (action, "active", widget, "sensitive", 0);
    

    Will result in the "sensitive" property of the widget #GObject instance to be updated with the same value of the "active" property of the action #GObject instance.

    If flags contains %G_BINDING_BIDIRECTIONAL then the binding will be mutual: if target_property on target changes then the source_property on source will be updated as well.

    The binding will automatically be removed when either the source or the target instances are finalized. To remove the binding without affecting the source and the target you can just call g_object_unref() on the returned #GBinding instance.

    Removing the binding by calling g_object_unref() on it must only be done if the binding, source and target are only used from a single thread and it is clear that both source and target outlive the binding. Especially it is not safe to rely on this if the binding, source or target can be finalized from different threads. Keep another reference to the binding and use g_binding_unbind() instead to be on the safe side.

    A #GObject can have multiple bindings.

    Parameters

    • sourceProperty: string

      the property on source to bind

    • target: GObject.Object

      the target #GObject

    • targetProperty: string

      the property on target to bind

    • flags: BindingFlags

      flags to pass to #GBinding

    Returns Binding

  • Creates a binding between source_property on source and target_property on target, allowing you to set the transformation functions to be used by the binding.

    This function is the language bindings friendly version of g_object_bind_property_full(), using #GClosures instead of function pointers.

    Parameters

    • sourceProperty: string

      the property on source to bind

    • target: GObject.Object

      the target #GObject

    • targetProperty: string

      the property on target to bind

    • flags: BindingFlags

      flags to pass to #GBinding

    • transformTo: TClosure<any, any>

      a #GClosure wrapping the transformation function from the source to the target, or %NULL to use the default

    • transformFrom: TClosure<any, any>

      a #GClosure wrapping the transformation function from the target to the source, or %NULL to use the default

    Returns Binding

  • canDelete(): boolean
  • canRemoveSupportsType(): boolean
  • connect(sigName: "notify::filename", callback: ((...args: any[]) => void)): number
  • connect(sigName: string, callback: ((...args: any[]) => void)): number
  • Parameters

    • sigName: "notify::filename"
    • callback: ((...args: any[]) => void)
        • (...args: any[]): void
        • Parameters

          • Rest ...args: any[]

          Returns void

    Returns number

  • Parameters

    • sigName: string
    • callback: ((...args: any[]) => void)
        • (...args: any[]): void
        • Parameters

          • Rest ...args: any[]

          Returns void

    Returns number

  • delete(): boolean
  • Tries to delete a #GAppInfo.

    On some platforms, there may be a difference between user-defined #GAppInfos which can be deleted, and system-wide ones which cannot. See g_app_info_can_delete().

    Returns boolean

  • emit(sigName: "notify::filename", ...args: any[]): void
  • emit(sigName: string, ...args: any[]): void
  • Checks if two #GAppInfos are equal.

    Note that the check may not compare each individual field, and only does an identity check. In case detecting changes in the contents is needed, program code must additionally compare relevant fields.

    Parameters

    • appinfo2: AppInfo

      the second #GAppInfo.

    Returns boolean

  • forceFloating(): void
  • This function is intended for #GObject implementations to re-enforce a [floating][floating-ref] object reference. Doing this is seldom required: all #GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling g_object_ref_sink().

    Returns void

  • freezeNotify(): void
  • Increases the freeze count on object. If the freeze count is non-zero, the emission of "notify" signals on object is stopped. The signals are queued until the freeze count is decreased to zero. Duplicate notifications are squashed so that at most one #GObject::notify signal is emitted for each property modified while the object is frozen.

    This is necessary for accessors that modify multiple properties to prevent premature notification while the object is still being modified.

    Returns void

  • getActionName(actionName: string): string
  • 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.

    Parameters

    • actionName: string

      the name of the action as from g_desktop_app_info_list_actions()

    Returns string

  • getBoolean(key: string): boolean
  • Looks up a boolean value in the keyfile backing info.

    The key is looked up in the "Desktop Entry" group.

    Parameters

    • key: string

      the key to look up

    Returns boolean

  • getCategories(): string
  • getCommandline(): string
  • getData(key?: string): object
  • Gets a named field from the objects table of associations (see g_object_set_data()).

    Parameters

    • Optional key: string

      name of the key for that association

    Returns object

  • getDescription(): string
  • getDisplayName(): string
  • Gets the display name of the application. The display name is often more descriptive to the user than the name itself.

    Returns string

  • getExecutable(): string
  • getFilename(): string
  • 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.

    Returns string

  • getGenericName(): string
  • getId(): string
  • Gets the ID of an application. An id is a string that identifies the application. The exact format of the id is platform dependent. For instance, on Unix this is the desktop file id from the xdg menu specification.

    Note that the returned ID may be %NULL, depending on how the appinfo has been constructed.

    Returns string

  • getIsHidden(): boolean
  • A desktop file is hidden if the Hidden key in it is set to True.

    Returns boolean

  • getKeywords(): string[]
  • getLocaleString(key: string): string
  • Looks up a localized string value in the keyfile backing info translated to the current locale.

    The key is looked up in the "Desktop Entry" group.

    Parameters

    • key: string

      the key to look up

    Returns string

  • getName(): string
  • getNodisplay(): boolean
  • 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 boolean

  • getProperty(propertyName?: string, value?: any): void
  • Gets a property of an object.

    The value can be:

    • an empty #GValue initialized by %G_VALUE_INIT, which will be automatically initialized with the expected type of the property (since GLib 2.60)
    • a #GValue initialized with the expected type of the property
    • a #GValue initialized with a type to which the expected type of the property can be transformed

    In general, a copy is made of the property contents and the caller is responsible for freeing the memory by calling g_value_unset().

    Note that g_object_get_property() is really intended for language bindings, g_object_get() is much more convenient for C programming.

    Parameters

    • Optional propertyName: string

      the name of the property to get

    • Optional value: any

      return location for the property value

    Returns void

  • getQdata(quark: number): object
  • This function gets back user data pointers stored via g_object_set_qdata().

    Parameters

    • quark: number

      A #GQuark, naming the user data pointer

    Returns object

  • getShowIn(desktopEnv: string): boolean
  • 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.

    Parameters

    • desktopEnv: string

      a string specifying a desktop name

    Returns boolean

  • getStartupWmClass(): string
  • Retrieves the StartupWMClass field from info. This represents the WM_CLASS property of the main window of the application, if launched through info.

    Returns string

  • getString(key: string): string
  • Looks up a string value in the keyfile backing info.

    The key is looked up in the "Desktop Entry" group.

    Parameters

    • key: string

      the key to look up

    Returns string

  • getStringList(key: string): string[]
  • Looks up a string list value in the keyfile backing info.

    The key is looked up in the "Desktop Entry" group.

    Parameters

    • key: string

      the key to look up

    Returns string[]

  • getSupportedTypes(): string[]
  • Retrieves the list of content types that app_info claims to support. If this information is not provided by the environment, this function will return %NULL. This function does not take in consideration associations added with g_app_info_add_supports_type(), but only those exported directly by the application.

    Returns string[]

  • getv(names: string[], values: any[]): void
  • Gets n_properties properties for an object. Obtained properties will be set to values. All properties must be valid. Warnings will be emitted and undefined behaviour may result if invalid properties are passed in.

    Parameters

    • names: string[]

      the names of each property to get

    • values: any[]

      the values of each property to get

    Returns void

  • hasKey(key: string): boolean
  • Returns whether key exists in the "Desktop Entry" group of the keyfile backing info.

    Parameters

    • key: string

      the key to look up

    Returns boolean

  • isFloating(): boolean
  • Launches the application. Passes files to the launched application as arguments, using the optional context to get information about the details of the launcher (like what screen it is on). On error, error will be set accordingly.

    To launch the application without arguments pass a %NULL files list.

    Note that even if the launch is successful the application launched can fail to start if it runs into problems during startup. There is no way to detect this.

    Some URIs can be changed when passed through a GFile (for instance unsupported URIs with strange formats like mailto:), so if you have a textual URI you want to pass in as argument, consider using g_app_info_launch_uris() instead.

    The launched application inherits the environment of the launching process, but it can be modified with g_app_launch_context_setenv() and g_app_launch_context_unsetenv().

    On UNIX, this function sets the GIO_LAUNCHED_DESKTOP_FILE environment variable with the path of the launched desktop file and GIO_LAUNCHED_DESKTOP_FILE_PID to the process id of the launched process. This can be used to ignore GIO_LAUNCHED_DESKTOP_FILE, should it be inherited by further processes. The DISPLAY and DESKTOP_STARTUP_ID environment variables are also set, based on information provided in context.

    Parameters

    Returns boolean

  • 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.

    Parameters

    • actionName: string

      the name of the action as from g_desktop_app_info_list_actions()

    • launchContext: Gio.AppLaunchContext

      a #GAppLaunchContext

    Returns void

  • Launches the application. This passes the uris to the launched application as arguments, using the optional context to get information about the details of the launcher (like what screen it is on). On error, error will be set accordingly.

    To launch the application without arguments pass a %NULL uris list.

    Note that even if the launch is successful the application launched can fail to start if it runs into problems during startup. There is no way to detect this.

    Parameters

    • uris: string[]

      a #GList containing URIs to launch.

    • context: Gio.AppLaunchContext

      a #GAppLaunchContext or %NULL

    Returns boolean

  • 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.

    Parameters

    Returns boolean

  • launchUrisAsManagerWithFds(uris: string[], launchContext: Gio.AppLaunchContext, spawnFlags: GLib.SpawnFlags, stdinFd: number, stdoutFd: number, stderrFd: number): boolean
  • 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.

    Parameters

    • uris: string[]

      List of URIs

    • launchContext: Gio.AppLaunchContext

      a #GAppLaunchContext

    • spawnFlags: GLib.SpawnFlags

      #GSpawnFlags, used for each process

    • stdinFd: number

      file descriptor to use for child's stdin, or -1

    • stdoutFd: number

      file descriptor to use for child's stdout, or -1

    • stderrFd: number

      file descriptor to use for child's stderr, or -1

    Returns boolean

  • Async version of g_app_info_launch_uris().

    The callback is invoked immediately after the application launch, but it waits for activation in case of D-Bus–activated applications and also provides extended error information for sandboxed applications, see notes for g_app_info_launch_default_for_uri_async().

    Parameters

    Returns void

  • listActions(): string[]
  • 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 string[]

  • notify(propertyName: string): void
  • Emits a "notify" signal for the property property_name on object.

    When possible, eg. when signaling a property change from within the class that registered the property, you should use g_object_notify_by_pspec() instead.

    Note that emission of the notify signal may be blocked with g_object_freeze_notify(). In this case, the signal emissions are queued and will be emitted (in reverse order) when g_object_thaw_notify() is called.

    Parameters

    • propertyName: string

      the name of a property installed on the class of object.

    Returns void

  • Emits a "notify" signal for the property specified by pspec on object.

    This function omits the property name lookup, hence it is faster than g_object_notify().

    One way to avoid using g_object_notify() from within the class that registered the properties, and using g_object_notify_by_pspec() instead, is to store the GParamSpec used with g_object_class_install_property() inside a static array, e.g.:

      enum
    {
    PROP_0,
    PROP_FOO,
    PROP_LAST
    };

    static GParamSpec *properties[PROP_LAST];

    static void
    my_object_class_init (MyObjectClass *klass)
    {
    properties[PROP_FOO] = g_param_spec_int ("foo", "Foo", "The foo",
    0, 100,
    50,
    G_PARAM_READWRITE);
    g_object_class_install_property (gobject_class,
    PROP_FOO,
    properties[PROP_FOO]);
    }

    and then notify a change on the "foo" property with:

      g_object_notify_by_pspec (self, properties[PROP_FOO]);
    

    Parameters

    • pspec: ParamSpec

      the #GParamSpec of a property installed on the class of object.

    Returns void

  • off(sigName: "notify::filename", callback: ((...args: any[]) => void)): EventEmitter
  • off(sigName: string, callback: ((...args: any[]) => void)): EventEmitter

    • sigName: string
    • callback: ((...args: any[]) => void)
        • (...args: any[]): void

          • Rest ...args: any[]

          Returns void

    • Optional after: boolean

    Returns EventEmitter

  • Increases the reference count of object.

    Since GLib 2.56, if GLIB_VERSION_MAX_ALLOWED is 2.56 or greater, the type of object will be propagated to the return type (using the GCC typeof() extension), so any casting the caller needs to do on the return type must be explicit.

    Returns GObject.Object

  • Increase the reference count of object, and possibly remove the [floating][floating-ref] reference, if object has a floating reference.

    In other words, if the object is floating, then this call "assumes ownership" of the floating reference, converting it to a normal reference by clearing the floating flag while leaving the reference count unchanged. If the object is not floating, then this call adds a new normal reference increasing the reference count by one.

    Since GLib 2.56, the type of object will be propagated to the return type under the same conditions as for g_object_ref().

    Returns GObject.Object

  • removeSupportsType(contentType: string): boolean
  • runDispose(): void
  • Releases all references to other objects. This can be used to break reference cycles.

    This function should only be called from object system implementations.

    Returns void

  • setAsDefaultForExtension(extension: string): boolean
  • Sets the application as the default handler for the given file extension.

    Parameters

    • extension: string

      a string containing the file extension (without the dot).

    Returns boolean

  • setAsDefaultForType(contentType: string): boolean
  • setAsLastUsedForType(contentType: string): boolean
  • Sets the application as the last used application for a given type. This will make the application appear as first in the list returned by g_app_info_get_recommended_for_type(), regardless of the default application for that content type.

    Parameters

    • contentType: string

      the content type.

    Returns boolean

  • setData(key: string, data?: object): void
  • Each object carries around a table of associations from strings to pointers. This function lets you set an association.

    If the object already had an association with that name, the old association will be destroyed.

    Internally, the key is converted to a #GQuark using g_quark_from_string(). This means a copy of key is kept permanently (even after object has been finalized) — so it is recommended to only use a small, bounded set of values for key in your program, to avoid the #GQuark storage growing unbounded.

    Parameters

    • key: string

      name of the key

    • Optional data: object

      data to associate with that key

    Returns void

  • setProperty(propertyName: string, value?: any): void
  • Sets a property on an object.

    Parameters

    • propertyName: string

      the name of the property to set

    • Optional value: any

      the value

    Returns void

  • shouldShow(): boolean
  • stealData(key?: string): object
  • Remove a specified datum from the object's data associations, without invoking the association's destroy handler.

    Parameters

    • Optional key: string

      name of the key

    Returns object

  • stealQdata(quark: number): object
  • This function gets back user data pointers stored via g_object_set_qdata() and removes the data from object without invoking its destroy() function (if any was set). Usually, calling this function is only required to update user data pointers with a destroy notifier, for example:

    void
    object_add_to_user_list (GObject *object,
    const gchar *new_string)
    {
    // the quark, naming the object data
    GQuark quark_string_list = g_quark_from_static_string ("my-string-list");
    // retrieve the old string list
    GList *list = g_object_steal_qdata (object, quark_string_list);

    // prepend new string
    list = g_list_prepend (list, g_strdup (new_string));
    // this changed 'list', so we need to set it again
    g_object_set_qdata_full (object, quark_string_list, list, free_string_list);
    }
    static void
    free_string_list (gpointer data)
    {
    GList *node, *list = data;

    for (node = list; node; node = node->next)
    g_free (node->data);
    g_list_free (list);
    }

    Using g_object_get_qdata() in the above example, instead of g_object_steal_qdata() would have left the destroy function set, and thus the partial string list would have been freed upon g_object_set_qdata_full().

    Parameters

    • quark: number

      A #GQuark, naming the user data pointer

    Returns object

  • supportsFiles(): boolean
  • supportsUris(): boolean
  • thawNotify(): void
  • Reverts the effect of a previous call to g_object_freeze_notify(). The freeze count is decreased on object and when it reaches zero, queued "notify" signals are emitted.

    Duplicate notifications for each property are squashed so that at most one #GObject::notify signal is emitted for each property, in the reverse order in which they have been queued.

    It is an error to call this function when the freeze count is zero.

    Returns void

  • unref(): void
  • Decreases the reference count of object. When its reference count drops to 0, the object is finalized (i.e. its memory is freed).

    If the pointer to the #GObject may be reused in future (for example, if it is an instance variable of another object), it is recommended to clear the pointer to %NULL rather than retain a dangling pointer to a potentially invalid #GObject instance. Use g_clear_object() for this.

    Returns void

  • watchClosure(closure: TClosure<any, any>): void
  • This function essentially limits the life time of the closure to the life time of the object. That is, when the object is finalized, the closure is invalidated by calling g_closure_invalidate() on it, in order to prevent invocations of the closure with a finalized (nonexisting) object. Also, g_object_ref() and g_object_unref() are added as marshal guards to the closure, to ensure that an extra reference count is held on object during invocation of the closure. Usually, this function will be called on closures that use this object as closure data.

    Parameters

    • closure: TClosure<any, any>

      #GClosure to watch

    Returns void

  • compatControl(what: number, data: object): number
  • 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.

    Parameters

    • interface: string

      the name of the interface

    Returns DesktopAppInfo[]

  • Find the #GParamSpec with the given name for an interface. Generally, the interface vtable passed in as g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek().

    Parameters

    • gIface: TypeInterface

      any interface vtable for the interface, or the default vtable for the interface

    • propertyName: string

      name of a property to look up.

    Returns ParamSpec

  • Add a property to an interface; this is only useful for interfaces that are added to GObject-derived types. Adding a property to an interface forces all objects classes with that interface to have a compatible property. The compatible property could be a newly created #GParamSpec, but normally g_object_class_override_property() will be used so that the object class only needs to provide an implementation and inherits the property description, default value, bounds, and so forth from the interface property.

    This function is meant to be called from the interface's default vtable initialization function (the class_init member of #GTypeInfo.) It must not be called after after class_init has been called for any object types implementing this interface.

    If pspec is a floating reference, it will be consumed.

    Parameters

    • gIface: TypeInterface

      any interface vtable for the interface, or the default vtable for the interface.

    • pspec: ParamSpec

      the #GParamSpec for the new property

    Returns void

  • Lists the properties of an interface.Generally, the interface vtable passed in as g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek().

    Parameters

    • gIface: TypeInterface

      any interface vtable for the interface, or the default vtable for the interface

    Returns ParamSpec[]

  • 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).

    Parameters

    • desktopId: string

      the desktop file id

    Returns DesktopAppInfo

  • Creates a new #GDesktopAppInfo.

    Parameters

    • filename: string

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

    Returns DesktopAppInfo

  • Creates a new instance of a #GObject subtype and sets its properties.

    Construction parameters (see %G_PARAM_CONSTRUCT, %G_PARAM_CONSTRUCT_ONLY) which are not explicitly specified are set to their default values.

    Parameters

    • objectType: GType<unknown>

      the type id of the #GObject subtype to instantiate

    • parameters: GObject.Parameter[]

      an array of #GParameter

    Returns GObject.Object

  • search(searchString: string): 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.

    Parameters

    • searchString: string

      the search string to use

    Returns string[]

  • setDesktopEnv(desktopEnv: string): void
  • 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.

    Parameters

    • desktopEnv: string

      a string specifying what desktop this is

    Returns void
