Methods

  • 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

  • close(): void
  • connect(sigName: "notify::fd", callback: ((...args: any[]) => void)): number
  • connect(sigName: "notify::flags", callback: ((...args: any[]) => void)): number
  • connect(sigName: string, callback: ((...args: any[]) => void)): number
  • Parameters

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

          • Rest ...args: any[]

          Returns void

    Returns number

  • Parameters

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

          • Rest ...args: any[]

          Returns void

    Returns number

  • Parameters

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

        • Parameters

          • Rest ...args: any[]

          Returns void

    Returns number

  • emit(sigName: "notify::fd", ...args: any[]): void
  • emit(sigName: "notify::flags", ...args: any[]): void
  • emit(sigName: string, ...args: any[]): void
  • 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

  • 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

  • getFd(): number
  • 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

  • getSize(): [boolean, number, number]
  • Reads the pseudo terminal's window size.

    If getting the window size failed, error will be set to a #GIOError.

    Returns [boolean, number, number]

  • 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

  • Initializes the object implementing the interface.

    This method is intended for language bindings. If writing in C, g_initable_new() should typically be used instead.

    The object must be initialized before any real use after initial construction, either with this function or g_async_initable_init_async().

    Implementations may also support cancellation. If cancellable is not %NULL, then initialization can be cancelled by triggering the cancellable object from another thread. If the operation was cancelled, the error %G_IO_ERROR_CANCELLED will be returned. If cancellable is not %NULL and the object doesn't support cancellable initialization the error %G_IO_ERROR_NOT_SUPPORTED will be returned.

    If the object is not initialized, or initialization returns with an error, then all operations on the object except g_object_ref() and g_object_unref() are considered to be invalid, and have undefined behaviour. See the [introduction][ginitable] for more details.

    Callers should not assume that a class which implements #GInitable can be initialized multiple times, unless the class explicitly documents itself as supporting this. Generally, a class’ implementation of init() can assume (and assert) that it will only be called once. Previously, this documentation recommended all #GInitable implementations should be idempotent; that recommendation was relaxed in GLib 2.54.

    If a class explicitly supports being initialized multiple times, it is recommended that the method is idempotent: multiple calls with the same arguments should return the same results. Only the first call initializes the object; further calls return the result of the first call.

    One reason why a class might need to support idempotent initialization is if it is designed to be used via the singleton pattern, with a #GObjectClass.constructor that sometimes returns an existing instance. In this pattern, a caller would expect to be able to call g_initable_init() on the result of g_object_new(), regardless of whether it is in fact a new instance.

    Parameters

    • Optional cancellable: Gio.Cancellable

      optional #GCancellable object, %NULL to ignore.

    Returns boolean

  • isFloating(): boolean
  • 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

    • 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

  • 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

  • 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

  • setSize(rows: number, columns: number): boolean
  • Attempts to resize the pseudo terminal's window size. If successful, the OS kernel will send SIGWINCH to the child process group.

    If setting the window size failed, error will be set to a #GIOError.

    Parameters

    • rows: number

      the desired number of rows

    • columns: number

      the desired number of columns

    Returns boolean

  • setUtf8(utf8: boolean): boolean
  • Tells the kernel whether the terminal is UTF-8 or not, in case it can make use of the info. Linux 2.6.5 or so defines IUTF8 to make the line discipline do multibyte backspace correctly.

    Parameters

    • utf8: boolean

      whether or not the pty is in UTF-8 mode

    Returns boolean

  • spawnAsync(workingDirectory: string, argv: string[], envv: string[], spawnFlags: GLib.SpawnFlags, timeout: number, cancellable: Gio.Cancellable): void
  • Like vte_pty_spawn_with_fds_async(), except that this function does not allow passing file descriptors to the child process. See vte_pty_spawn_with_fds_async() for more information.

    Parameters

    • workingDirectory: string

      the name of a directory the command should start in, or %NULL to use the current working directory

    • argv: string[]

      child's argument vector

    • envv: string[]

      a list of environment variables to be added to the environment before starting the process, or %NULL

    • spawnFlags: GLib.SpawnFlags

      flags from #GSpawnFlags

    • timeout: number

      a timeout value in ms, -1 for the default timeout, or G_MAXINT to wait indefinitely

    • cancellable: Gio.Cancellable

      a #GCancellable, or %NULL

    Returns void

  • spawnWithFdsAsync(workingDirectory: string, argv: string[], envv: string[], fds: number[], mapFds: number[], spawnFlags: GLib.SpawnFlags, timeout: number, cancellable: Gio.Cancellable): void
  • Starts the specified command under the pseudo-terminal pty. The argv and envv lists should be %NULL-terminated. The "TERM" environment variable is automatically set to a default value, but can be overridden from envv. pty_flags controls logging the session to the specified system log files.

    Note also that %G_SPAWN_STDOUT_TO_DEV_NULL, %G_SPAWN_STDERR_TO_DEV_NULL, and %G_SPAWN_CHILD_INHERITS_STDIN are not supported in spawn_flags, since stdin, stdout and stderr of the child process will always be connected to the PTY. Also %G_SPAWN_LEAVE_DESCRIPTORS_OPEN is not supported; and %G_SPAWN_DO_NOT_REAP_CHILD will always be added to spawn_flags.

    If fds is not %NULL, the child process will map the file descriptors from fds according to map_fds; n_map_fds must be less or equal to n_fds. This function will take ownership of the file descriptors in fds; you must not use or close them after this call. All file descriptors in fds must have the FD_CLOEXEC flag set on them; it will be unset in the child process before calling man:execve(2). Note also that no file descriptor may be mapped to stdin, stdout, or stderr (file descriptors 0, 1, or 2), since these will be assigned to the PTY. All open file descriptors apart from those mapped as above will be closed when execve() is called.

    Beginning with 0.60, and on linux only, and unless %VTE_SPAWN_NO_SYSTEMD_SCOPE is passed in spawn_flags, the newly created child process will be moved to its own systemd user scope; and if %VTE_SPAWN_REQUIRE_SYSTEMD_SCOPE is passed, and creation of the systemd user scope fails, the whole spawn will fail. You can override the options used for the systemd user scope by providing a systemd override file for 'vte-spawn-.scope' unit. See man:systemd.unit(5) for further information.

    See vte_pty_new(), and vte_terminal_watch_child() for more information.

    Parameters

    • workingDirectory: string

      the name of a directory the command should start in, or %NULL to use the current working directory

    • argv: string[]

      child's argument vector

    • envv: string[]

      a list of environment variables to be added to the environment before starting the process, or %NULL

    • fds: number[]

      an array of file descriptors, or %NULL

    • mapFds: number[]

      an array of integers, or %NULL

    • spawnFlags: GLib.SpawnFlags

      flags from #GSpawnFlags

    • timeout: number

      a timeout value in ms, -1 for the default timeout, or G_MAXINT to wait indefinitely

    • cancellable: Gio.Cancellable

      a #GCancellable, or %NULL

    Returns void

  • 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

  • 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
  • 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 #VtePty for the PTY master fd.

    No entry will be made in the lastlog, utmp or wtmp system files.

    Note that the newly created #VtePty will take ownership of fd and close it on finalize.

    Parameters

    • fd: number

      a file descriptor to the PTY

    • cancellable: Gio.Cancellable

      a #GCancellable, or %NULL

    Returns Pty

  • Allocates a new pseudo-terminal.

    You can later use fork() or the g_spawn_async() family of functions to start a process on the PTY.

    If using fork(), you MUST call vte_pty_child_setup() in the child.

    If using g_spawn_async() and friends, you MUST either use vte_pty_child_setup() directly as the child setup function, or call vte_pty_child_setup() from your own child setup function supplied.

    When using vte_terminal_spawn_sync() with a custom child setup function, vte_pty_child_setup() will be called before the supplied function; you must not call it again.

    Also, you MUST pass the %G_SPAWN_DO_NOT_REAP_CHILD flag.

    Note also that %G_SPAWN_STDOUT_TO_DEV_NULL, %G_SPAWN_STDERR_TO_DEV_NULL, and %G_SPAWN_CHILD_INHERITS_STDIN are not supported, since stdin, stdout and stderr of the child process will always be connected to the PTY.

    Note that you should set the PTY's size using vte_pty_set_size() before spawning the child process, so that the child process has the correct size from the start instead of starting with a default size and then shortly afterwards receiving a SIGWINCH signal. You should prefer using vte_terminal_pty_new_sync() which does this automatically.

    Parameters

    Returns Pty

  • 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
