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

  • emit(sigName: "started", ...args: any[]): void
  • emit(sigName: "update", ...args: any[]): void
  • emit(sigName: "finished", ...args: any[]): void
  • emit(sigName: "begin-clear", ...args: any[]): void
  • emit(sigName: "end-clear", ...args: any[]): void
  • emit(sigName: "notify::limit", ...args: any[]): void
  • emit(sigName: "notify::sort-mode", ...args: any[]): void
  • emit(sigName: "notify::repository", ...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

  • Calls func on each node in model in a depth-first fashion.

    If func returns %TRUE, then the tree ceases to be walked, and gtk_tree_model_foreach() returns.

    Parameters

    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

  • getColumnType(index: number): GType<unknown>
  • 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

  • Returns a set of flags supported by this interface.

    The flags are a bitwise combination of #GtkTreeModelFlags. The flags supported should not change during the lifetime of the tree_model.

    Returns Gtk.TreeModelFlags

  • getInclude(): OId[]
  • getIterFromString(pathString: string): [boolean, Gtk.TreeIter]
  • Sets iter to a valid iterator pointing to path_string, if it exists. Otherwise, iter is left invalid and %FALSE is returned.

    Parameters

    • pathString: string

      a string representation of a #GtkTreePath-struct

    Returns [boolean, Gtk.TreeIter]

  • getLimit(): number
  • getNColumns(): number
  • getPermanentLanes(): OId[]
  • 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

  • Generates a string representation of the iter.

    This string is a “:” separated list of numbers. For example, “4:10:0:3” would be an acceptable return value for this string.

    Parameters

    Returns string

  • Initializes and sets value to that at column.

    When done with value, g_value_unset() needs to be called to free any allocated memory.

    Parameters

    • iter: Gtk.TreeIter

      the #GtkTreeIter-struct

    • column: number

      the column to lookup the value at

    Returns any

  • 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

  • isFloating(): boolean
  • Sets iter to point to the first child of parent.

    If parent has no children, %FALSE is returned and iter is set to be invalid. parent will remain a valid node after this function has been called.

    If parent is %NULL returns the first node, equivalent to gtk_tree_model_get_iter_first (tree_model, iter);

    Parameters

    • parent: Gtk.TreeIter

      the #GtkTreeIter-struct, or %NULL

    Returns [boolean, Gtk.TreeIter]

  • Returns the number of children that iter has.

    As a special case, if iter is %NULL, then the number of toplevel nodes is returned.

    Parameters

    Returns number

  • Sets iter to point to the node following it at the current level.

    If there is no next iter, %FALSE is returned and iter is set to be invalid.

    Parameters

    Returns boolean

  • Sets iter to be the child of parent, using the given index.

    The first index is 0. If n is too big, or parent has no children, iter is set to an invalid iterator and %FALSE is returned. parent will remain a valid node after this function has been called. As a special case, if parent is %NULL, then the n-th root node is set.

    Parameters

    • parent: Gtk.TreeIter

      the #GtkTreeIter-struct to get the child from, or %NULL.

    • n: number

      the index of the desired child

    Returns [boolean, Gtk.TreeIter]

  • Sets iter to be the parent of child.

    If child is at the toplevel, and doesn’t have a parent, then iter is set to an invalid iterator and %FALSE is returned. child will remain a valid node after this function has been called.

    iter will be initialized before the lookup is performed, so child and iter cannot point to the same memory location.

    Parameters

    Returns [boolean, Gtk.TreeIter]

  • Sets iter to point to the previous node at the current level.

    If there is no previous iter, %FALSE is returned and iter is set to be invalid.

    Parameters

    Returns 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

  • on(sigName: "started", callback: CommitModel_StartedSignalCallback, after?: boolean): EventEmitter
  • on(sigName: "update", callback: CommitModel_UpdateSignalCallback, after?: boolean): EventEmitter
  • on(sigName: "finished", callback: CommitModel_FinishedSignalCallback, after?: boolean): EventEmitter
  • on(sigName: "begin-clear", callback: CommitModel_BeginClearSignalCallback, after?: boolean): EventEmitter
  • on(sigName: "end-clear", callback: CommitModel_EndClearSignalCallback, after?: boolean): EventEmitter
  • on(sigName: "notify::limit", callback: ((...args: any[]) => void), after?: boolean): EventEmitter

  • on(sigName: "notify::repository", callback: ((...args: any[]) => void), after?: boolean): EventEmitter
  • on(sigName: string, callback: ((...args: any[]) => void), after?: boolean): EventEmitter
  • once(sigName: "started", callback: CommitModel_StartedSignalCallback, after?: boolean): EventEmitter
  • once(sigName: "update", callback: CommitModel_UpdateSignalCallback, after?: boolean): EventEmitter
  • once(sigName: "finished", callback: CommitModel_FinishedSignalCallback, after?: boolean): EventEmitter
  • once(sigName: "begin-clear", callback: CommitModel_BeginClearSignalCallback, after?: boolean): EventEmitter
  • once(sigName: "end-clear", callback: CommitModel_EndClearSignalCallback, after?: boolean): EventEmitter
  • once(sigName: "notify::limit", callback: ((...args: any[]) => void), after?: boolean): EventEmitter
  • once(sigName: "notify::sort-mode", callback: ((...args: any[]) => void), after?: boolean): EventEmitter
  • once(sigName: "notify::repository", callback: ((...args: any[]) => void), after?: boolean): EventEmitter
  • once(sigName: string, callback: ((...args: any[]) => void), after?: boolean): 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

  • Lets the tree ref the node.

    This is an optional method for models to implement. To be more specific, models may ignore this call as it exists primarily for performance reasons.

    This function is primarily meant as a way for views to let caching models know when nodes are being displayed (and hence, whether or not to cache that node). Being displayed means a node is in an expanded branch, regardless of whether the node is currently visible in the viewport. For example, a file-system based model would not want to keep the entire file-hierarchy in memory, just the sections that are currently being displayed by every current view.

    A model should be expected to be able to get an iter independent of its reffed state.

    Parameters

    Returns void

  • 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

  • reload(): void
  • Emits the #GtkTreeModel::row-deleted signal on tree_model.

    This should be called by models after a row has been removed. The location pointed to by path should be the location that the row previously was at. It may not be a valid location anymore.

    Nodes that are deleted are not unreffed, this means that any outstanding references on the deleted node should not be released.

    Parameters

    • path: Gtk.TreePath

      a #GtkTreePath-struct pointing to the previous location of the deleted row

    Returns void

  • Emits the #GtkTreeModel::row-has-child-toggled signal on tree_model. This should be called by models after the child state of a node changes.

    Parameters

    • path: Gtk.TreePath

      a #GtkTreePath-struct pointing to the changed row

    • iter: Gtk.TreeIter

      a valid #GtkTreeIter-struct pointing to the changed row

    Returns void

  • Emits the #GtkTreeModel::rows-reordered signal on tree_model.

    This should be called by models when their rows have been reordered.

    Parameters

    • path: Gtk.TreePath

      a #GtkTreePath-struct pointing to the tree node whose children have been reordered

    • iter: Gtk.TreeIter

      a valid #GtkTreeIter-struct pointing to the node whose children have been reordered, or %NULL if the depth of path is 0

    • newOrder: number[]

      an array of integers mapping the current position of each child to its old position before the re-ordering, i.e. new_order``[newpos] = oldpos

    Returns void

  • 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

  • setExclude(ids: OId[]): void
  • setInclude(ids: OId[]): void
  • setLimit(value: number): void
  • setPermanentLanes(value: OId[]): 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

  • size(): number
  • 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

  • Lets the tree unref the node.

    This is an optional method for models to implement. To be more specific, models may ignore this call as it exists primarily for performance reasons. For more information on what this means, see gtk_tree_model_ref_node().

    Please note that nodes that are deleted are not unreffed.

    Parameters

    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 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
