Methods

  • Like dee_model_append() but intended for language bindings or situations where you work with models on a meta level and may not have a prior knowledge of the column schemas of the models. See also dee_model_build_row().

    Parameters

    • row_members: GLib.Variant[]

      An array of #GVariants with type signature matching those of the column schemas of self. If any of the variants have floating references they will be consumed

    Returns Dee.ModelIter

  • begin_changeset(): void
  • Notify listeners that the model is about to be changed, which means that multiple row additions / changes / removals will follow. The default implementation of this method will emit the ::changeset-started signal.

    It is not stricly necessary to enclose every change to a model in a dee_model_begin_changeset() and dee_model_end_changeset() calls, but doing so is highly recommended and allows implementing various optimizations.

    The usual way to perform multiple changes to a model is as follows:

    void update_model (DeeModel *model) { GVariant **added_row_data1 = ...; GVariant **added_row_data2 = ...;

    dee_model_begin_changeset (model);

    dee_model_remove (model, dee_model_get_first_iter (model)); dee_model_append_row (model, added_row_data1); dee_model_append_row (model, added_row_data2);

    dee_model_end_changeset (model); }

    Returns void

  • 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

    • source_property: string

      the property on source to bind

    • target: GObject.Object

      the target #GObject

    • target_property: 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

    • source_property: string

      the property on source to bind

    • target: GObject.Object

      the target #GObject

    • target_property: string

      the property on target to bind

    • flags: BindingFlags

      flags to pass to #GBinding

    • transform_to: TClosure<any, any>

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

    • transform_from: TClosure<any, any>

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

    Returns Binding

  • clear(): void
  • connect(sigName: string, callback: ((...args: any[]) => void)): number
  • connect_after(sigName: string, callback: ((...args: any[]) => void)): number
  • disconnect(id: number): void
  • emit(sigName: string, ...args: any[]): void
  • end_changeset(): void
  • Notify listeners that all changes have been committed to the model. The default implementation of this method will emit the ::changeset-finished signal.

    See also dee_model_begin_changeset().

    Returns void

  • Build an externalized form of self which can be used together with dee_serializable_parse_external() to rebuild a copy of self.

    It is important to note that the variant returned from this method does not have the same type signature as returned from a call to dee_serializable_serialize(). Externalization will wrap the serialized data in a container format with versioning information and headers with type information.

    Returns GLib.Variant

  • Finds a row in self according to the sorting specified by cmp_func. This method will assume that self is already sorted by cmp_func.

    If you use this method for searching you should only use dee_model_insert_row_sorted() to insert rows in the model.

    Parameters

    • row_spec: GLib.Variant[]

      An array of #GVariants with type signature matching those of the column schemas of self. No references will be taken on the variants.

    • cmp_func: CompareRowFunc

      Callback used for comparison or rows

    Returns [Dee.ModelIter, boolean]

  • Like dee_model_find_row_sorted(), but uses DeeCompareRowSizedFunc and therefore doesn't cause trouble when used from introspected languages.

    Finds a row in self according to the sorting specified by cmp_func. This method will assume that self is already sorted by cmp_func.

    If you use this method for searching you should only use dee_model_insert_row_sorted() (or dee_model_insert_row_sorted_with_sizes()) to insert rows in the model.

    Parameters

    • row_spec: GLib.Variant[]

      An array of #GVariants with type signature matching those of the column schemas of self. No references will be taken on the variants.

    • cmp_func: CompareRowSizedFunc

      Callback used for comparison or rows

    Returns [Dee.ModelIter, boolean]

  • force_floating(): 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

  • freeze_notify(): 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

  • get_column_index(column_name: string): number
  • get_column_names(): string[]
  • get_column_schema(column: number): string
  • get_data(key?: string): object
  • get_field_schema(field_name: string): [string, number]
  • get_n_columns(): number
  • get_n_rows(): number
  • get_property(property_name?: 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 property_name: string

      the name of the property to get

    • Optional value: any

      return location for the property value

    Returns void

  • get_qdata(quark: number): object
  • get_schema(): string[]
  • get_seqnum(): number
  • get_vardict_schema(column: number): HashTable<string | number | symbol, string | number | boolean>
  • 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

  • inc_seqnum(): number
  • As dee_model_insert(), but intended for language bindings or situations where you work with models on a meta level and may not have a priori knowledge of the column schemas of the models. See also dee_model_build_row().

    Parameters

    • pos: number

      The index to insert the row on. The existing row will be pushed down.

    • row_members: GLib.Variant[]

      An array of #GVariants with type signature matching those of the column schemas of self. If any of the variants have floating references they will be consumed.

    Returns Dee.ModelIter

  • As dee_model_insert_before(), but intended for language bindings or situations where you work with models on a meta level and may not have a priori knowledge of the column schemas of the models. See also dee_model_build_row().

    Parameters

    • iter: Dee.ModelIter

      An iter pointing to the row before which to insert the new one

    • row_members: GLib.Variant[]

      An array of #GVariants with type signature matching those of the column schemas of self. If any of the variants have floating references they will be consumed.

    Returns Dee.ModelIter

  • Inserts a row in self according to the sorting specified by cmp_func. If you use this method for insertion you should not use other methods as this method assumes the model to be already sorted by cmp_func.

    Parameters

    • row_members: GLib.Variant[]

      An array of #GVariants with type signature matching those of the column schemas of self. If any of the variants have floating references they will be consumed.

    • cmp_func: CompareRowFunc

      Callback used for comparison or rows

    Returns Dee.ModelIter

  • Inserts a row in self according to the sorting specified by cmp_func. If you use this method for insertion you should not use other methods as this method assumes the model to be already sorted by cmp_func.

    Parameters

    • row_members: GLib.Variant[]

      An array of #GVariants with type signature matching those of the column schemas of self. If any of the variants have floating references they will be consumed.

    • cmp_func: CompareRowSizedFunc

      Callback used for comparison or rows

    Returns Dee.ModelIter

  • is_floating(): boolean
  • notify(property_name: 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

    • property_name: 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

  • Like dee_model_prepend() but intended for language bindings or situations where you work with models on a meta level and may not have a priori knowledge of the column schemas of the models. See also dee_model_build_row().

    Parameters

    • row_members: GLib.Variant[]

      An array of #GVariants with type signature matching those of the column schemas of self. If any of the variants have floating references they will be consumed.

    Returns Dee.ModelIter

  • 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

  • Register a new tag on a #DeeModel. A tag is an extra value attached to a given row on a model. The tags are invisible to all that doesn't have the tag handle returned by this method. #DeeModel implementations must ensure that dee_model_get_tag() is an O(1) operation.

    Tags can be very useful in associating some extra data to a row in a model and have that automatically synced when the model changes. If you're writing a tiled view for a model you might want to tag each row with the tile widget for that row. That way you have very convenient access to the tile widget given any row in the model.

    The private nature of tags and the fact that you can store arbitrary pointers and binary data in them also means that they are not serialized if you utilize a model implementation that exposes the #DeeSerializable interface.

    Parameters

    • tag_destroy: GLib.DestroyNotify

      Function called when a tagged row is removed from the model. This function will also be called on all tagged rows when the model is finalized.

    Returns ModelTag

  • register_vardict_schema(column: number, schemas: HashTable<string | number | symbol, string | number | boolean>): void
  • Register schema for fields in a model containing column with variant dictionary schema ('a{sv}'). The keys registered with this function can be later used with dee_model_build_named_row() function, as well as dee_model_get_value_by_name(). Note that it is possible to register the same field name for multiple columns, in which case you need to use fully-qualified "column_name::field" name in the calls to dee_model_build_named_row() and dee_model_get_field_schema().

    Parameters

    • column: number

      the column index to register the schemas with

    • schemas: HashTable<string | number | symbol, string | number | boolean>

      hashtable with keys specifying names of the fields and values defining their schema

    Returns void

  • run_dispose(): void
  • Build a clean serialized representation of self. The signature of the returned variant is entirely determined by the underlying implementation. You can recreate a serialized instance by calling dee_serializable_parse() provided that you know the correct #GType for the serialized instance.

    Returns GLib.Variant

  • set_column_names_full(column_names: string[]): void
  • Set column names used by self. This method must be called exactly once, but only after setting a schema of the model. Note that some constructors will do this for you.

    Parameters

    • column_names: string[]

      A list of column names terminated by a %NULL

    Returns void

  • set_data(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

  • set_property(property_name: string, value?: any): void
  • Sets all columns in the row iter points to, to those found in row_members. The variants in row_members must match the types defined in the model's schema.

    Parameters

    • iter: Dee.ModelIter

      a #DeeModelIter

    • row_members: GLib.Variant[]

      And array of #GVariants with type signature matching those from the model schema. If any of the variants have floating references these will be consumed

    Returns void

  • set_schema_full(column_schemas: string[]): void
  • Set the #GVariant types and the number of columns used by self. This method must be called exactly once before using self. Note that some constructors will do this for you.

    Parameters

    • column_schemas: string[]

      A list of #GVariant type strings terminated by a %NULL

    Returns void

  • set_seqnum(seqnum: number): void
  • Set a tag on a row in a model. This function is guaranteed to be O(1). See also dee_model_register_tag().

    If tag is already set on this row the existing tag value will be destroyed with the #GDestroyNotify passed to the dee_model_register_tag().

    Parameters

    • iter: Dee.ModelIter

      The row to set the tag on

    • tag: ModelTag

      The tag handle for the tag as obtained from dee_model_register_tag()

    • value: object

      The value to set for tag. Note that %NULL represents an unset tag

    Returns void

  • Sets the data in column for the row iter points to, to value. The type of value must be convertible to the type of the column.

    When this method call completes the model will emit ::row-changed. You can edit the model in place without triggering the change signals by calling dee_model_set_value_silently().

    Parameters

    • iter: Dee.ModelIter

      a #DeeModelIter

    • column: number

      column number to set the value

    • value: GLib.Variant

      New value for cell. If value is a floating reference the model will assume ownership of the variant

    Returns void

  • steal_data(key?: string): object
  • steal_qdata(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

  • thaw_notify(): 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

  • Like dee_model_append() but intended for language bindings or situations where you work with models on a meta level and may not have a prior knowledge of the column schemas of the models. See also dee_model_build_row().

    virtual

    Parameters

    • row_members: GLib.Variant[]

      An array of #GVariants with type signature matching those of the column schemas of self. If any of the variants have floating references they will be consumed

    Returns Dee.ModelIter

  • vfunc_begin_changeset(): void
  • Notify listeners that the model is about to be changed, which means that multiple row additions / changes / removals will follow. The default implementation of this method will emit the ::changeset-started signal.

    It is not stricly necessary to enclose every change to a model in a dee_model_begin_changeset() and dee_model_end_changeset() calls, but doing so is highly recommended and allows implementing various optimizations.

    The usual way to perform multiple changes to a model is as follows:

    void update_model (DeeModel *model) { GVariant **added_row_data1 = ...; GVariant **added_row_data2 = ...;

    dee_model_begin_changeset (model);

    dee_model_remove (model, dee_model_get_first_iter (model)); dee_model_append_row (model, added_row_data1); dee_model_append_row (model, added_row_data2);

    dee_model_end_changeset (model); }

    virtual

    Returns void

  • vfunc_changeset_finished(): void
  • vfunc_changeset_started(): void
  • vfunc_clear(): void
  • vfunc_constructed(): void
  • vfunc_dispatch_properties_changed(n_pspecs: number, pspecs: ParamSpec): void
  • vfunc_dispose(): void
  • vfunc_end_changeset(): void
  • vfunc_finalize(): void
  • Finds a row in self according to the sorting specified by cmp_func. This method will assume that self is already sorted by cmp_func.

    If you use this method for searching you should only use dee_model_insert_row_sorted() to insert rows in the model.

    virtual

    Parameters

If you're writing a tiled view for a model you might want to tag each row with the tile widget for that row. That way you have very convenient access to the tile widget given any row in the model.

    The private nature of tags and the fact that you can store arbitrary pointers and binary data in them also means that they are not serialized if you utilize a model implementation that exposes the #DeeSerializable interface.

    virtual

    Parameters

    • tag_destroy: GLib.DestroyNotify

      Function called when a tagged row is removed from the model. This function will also be called on all tagged rows when the model is finalized.

    Returns ModelTag

  • vfunc_register_vardict_schema(num_column: number, schemas: HashTable<string | number | symbol, string | number | boolean>): void
  • Register schema for fields in a model containing column with variant dictionary schema ('a{sv}'). The keys registered with this function can be later used with dee_model_build_named_row() function, as well as dee_model_get_value_by_name(). Note that it is possible to register the same field name for multiple columns, in which case you need to use fully-qualified "column_name::field" name in the calls to dee_model_build_named_row() and dee_model_get_field_schema().

    virtual

    Parameters

    • num_column: number
    • schemas: HashTable<string | number | symbol, string | number | boolean>

      hashtable with keys specifying names of the fields and values defining their schema

    Returns void

  • Build a clean serialized representation of self. The signature of the returned variant is entirely determined by the underlying implementation. You can recreate a serialized instance by calling dee_serializable_parse() provided that you know the correct #GType for the serialized instance.

    virtual

    Returns GLib.Variant

  • vfunc_set_column_names_full(column_names: string[]): void
  • Set column names used by self. This method must be called exactly once, but only after setting a schema of the model. Note that some constructors will do this for you.

    virtual

    Parameters

    • column_names: string[]

      A list of column names terminated by a %NULL

    Returns void

  • vfunc_set_property(property_id: number, value?: any, pspec?: ParamSpec): void
  • Sets all columns in the row iter points to, to those found in row_members. The variants in row_members must match the types defined in the model's schema.

    virtual

    Parameters

    • iter: Dee.ModelIter

      a #DeeModelIter

    • row_members: GLib.Variant[]

      And array of #GVariants with type signature matching those from the model schema. If any of the variants have floating references these will be consumed

    Returns void

  • vfunc_set_schema_full(column_schemas: string[]): void
  • Set the #GVariant types and the number of columns used by self. This method must be called exactly once before using self. Note that some constructors will do this for you.

    virtual

    Parameters

    • column_schemas: string[]

      A list of #GVariant type strings terminated by a %NULL

    Returns void

  • Set a tag on a row in a model. This function is guaranteed to be O(1). See also dee_model_register_tag().

    If tag is already set on this row the existing tag value will be destroyed with the #GDestroyNotify passed to the dee_model_register_tag().

    virtual

    Parameters

    • iter: Dee.ModelIter

      The row to set the tag on

    • tag: ModelTag

      The tag handle for the tag as obtained from dee_model_register_tag()

    • value: object

      The value to set for tag. Note that %NULL represents an unset tag

    Returns void

  • Sets the data in column for the row iter points to, to value. The type of value must be convertible to the type of the column.

    When this method call completes the model will emit ::row-changed. You can edit the model in place without triggering the change signals by calling dee_model_set_value_silently().

    virtual

    Parameters

    • iter: Dee.ModelIter

      a #DeeModelIter

    • column: number

      column number to set the value

    • value: GLib.Variant

      New value for cell. If value is a floating reference the model will assume ownership of the variant

    Returns void

  • watch_closure(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

  • compat_control(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

    • g_iface: TypeInterface

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

    • property_name: 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

    • g_iface: TypeInterface

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

    • pspec: ParamSpec

      the #GParamSpec for the new property

    Returns void

  • 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

    • object_type: GType<unknown>

      the type id of the #GObject subtype to instantiate

    • parameters: GObject.Parameter[]

      an array of #GParameter

    Returns GObject.Object
