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

    • 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

  • disconnect(id: number): void
  • Draw page page_nr for printing on the the Cairo context encapsuled in context.

    This method has been designed to be called in the handler of the #GtkPrintOperation::draw_page signal as shown in the following example:

    // Signal handler for the GtkPrintOperation::draw_page signal

    static void draw_page (GtkPrintOperation *operation, GtkPrintContext *context, gint page_nr, gpointer user_data) { GtkSourcePrintCompositor *compositor;

    compositor = GTK_SOURCE_PRINT_COMPOSITOR (user_data);

    gtk_source_print_compositor_draw_page (compositor,
    context,
    page_nr);

    }

    Parameters

    • context: Gtk.PrintContext

      the #GtkPrintContext encapsulating the context information that is required when drawing the page for printing.

    • page_nr: number

      the number of the page to print.

    Returns void

  • emit(sigName: "notify::body-font-name", ...args: any[]): void
  • emit(sigName: "notify::buffer", ...args: any[]): void
  • emit(sigName: "notify::footer-font-name", ...args: any[]): void
  • emit(sigName: "notify::header-font-name", ...args: any[]): void
  • emit(sigName: "notify::highlight-syntax", ...args: any[]): void
  • emit(sigName: "notify::line-numbers-font-name", ...args: any[]): void
  • emit(sigName: "notify::n-pages", ...args: any[]): void
  • emit(sigName: "notify::print-footer", ...args: any[]): void
  • emit(sigName: "notify::print-header", ...args: any[]): void
  • emit(sigName: "notify::print-line-numbers", ...args: any[]): void
  • emit(sigName: "notify::tab-width", ...args: any[]): void
  • emit(sigName: "notify::wrap-mode", ...args: any[]): void
  • emit(sigName: string, ...args: any[]): void
  • 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_body_font_name(): string
  • Returns the name of the font used to print the text body. The returned string must be freed with g_free().

    Returns string

  • get_bottom_margin(unit: Gtk.Unit): number
  • get_data(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

  • get_footer_font_name(): string
  • Returns the name of the font used to print the page footer. The returned string must be freed with g_free().

    Returns string

  • get_header_font_name(): string
  • Returns the name of the font used to print the page header. The returned string must be freed with g_free().

    Returns string

  • get_highlight_syntax(): boolean
  • Determines whether the printed text will be highlighted according to the buffer rules. Note that highlighting will happen only if the buffer to print has highlighting activated.

    Returns boolean

  • get_left_margin(unit: Gtk.Unit): number
  • get_line_numbers_font_name(): string
  • Returns the name of the font used to print line numbers on the left margin. The returned string must be freed with g_free().

    Returns string

  • get_n_pages(): number
  • get_pagination_progress(): number
  • get_print_footer(): boolean
  • Determines if a footer is set to be printed for each page. A footer will be printed if this function returns %TRUE and some format strings have been specified with gtk_source_print_compositor_set_footer_format().

    Returns boolean

  • get_print_header(): boolean
  • Determines if a header is set to be printed for each page. A header will be printed if this function returns %TRUE and some format strings have been specified with gtk_source_print_compositor_set_header_format().

    Returns boolean

  • get_print_line_numbers(): number
  • Returns the interval used for line number printing. If the value is 0, no line numbers will be printed. The default value is 1 (i.e. numbers printed in all lines).

    Returns 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_right_margin(unit: Gtk.Unit): number
  • get_tab_width(): number
  • get_top_margin(unit: Gtk.Unit): 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

  • 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

  • Paginate the document associated with the compositor.

    In order to support non-blocking pagination, document is paginated in small chunks. Each time gtk_source_print_compositor_paginate() is invoked, a chunk of the document is paginated. To paginate the entire document, gtk_source_print_compositor_paginate() must be invoked multiple times. It returns %TRUE if the document has been completely paginated, otherwise it returns %FALSE.

    This method has been designed to be invoked in the handler of the #GtkPrintOperation::paginate signal, as shown in the following example:

    // Signal handler for the GtkPrintOperation::paginate signal

    static gboolean paginate (GtkPrintOperation *operation, GtkPrintContext *context, gpointer user_data) { GtkSourcePrintCompositor *compositor;

    compositor = GTK_SOURCE_PRINT_COMPOSITOR (user_data);

    if (gtk_source_print_compositor_paginate (compositor, context))
    {
    gint n_pages;

    n_pages = gtk_source_print_compositor_get_n_pages (compositor);
    gtk_print_operation_set_n_pages (operation, n_pages);

    return TRUE;
    }

    return FALSE;

    }

    If you don't need to do pagination in chunks, you can simply do it all in the #GtkPrintOperation::begin-print handler, and set the number of pages from there, like in the following example:

    // Signal handler for the GtkPrintOperation::begin-print signal

    static void begin_print (GtkPrintOperation *operation, GtkPrintContext *context, gpointer user_data) { GtkSourcePrintCompositor *compositor; gint n_pages;

    compositor = GTK_SOURCE_PRINT_COMPOSITOR (user_data);

    while (!gtk_source_print_compositor_paginate (compositor, context));

    n_pages = gtk_source_print_compositor_get_n_pages (compositor);
    gtk_print_operation_set_n_pages (operation, n_pages);

    }

    Parameters

    • context: Gtk.PrintContext

      the #GtkPrintContext whose parameters (e.g. paper size, print margins, etc.) are used by the the compositor to paginate the document.

    Returns boolean

  • 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

  • run_dispose(): 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

  • set_body_font_name(font_name: string): void
  • Sets the default font for the printed text.

    font_name should be a string representation of a font description Pango can understand. (e.g. "Monospace 10"). See pango_font_description_from_string() for a description of the format of the string representation.

    This function cannot be called anymore after the first call to the gtk_source_print_compositor_paginate() function.

    Parameters

    • font_name: string

      the name of the default font for the body text.

    Returns void

  • set_bottom_margin(margin: number, unit: Gtk.Unit): void
  • Sets the bottom margin used by compositor.

    Parameters

    • margin: number

      the new bottom margin in units of unit.

    • unit: Gtk.Unit

      the units for margin.

    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_footer_font_name(font_name: string): void
  • Sets the font for printing the page footer. If %NULL is supplied, the default font (i.e. the one being used for the text) will be used instead.

    font_name should be a string representation of a font description Pango can understand. (e.g. "Monospace 10"). See pango_font_description_from_string() for a description of the format of the string representation.

    This function cannot be called anymore after the first call to the gtk_source_print_compositor_paginate() function.

    Parameters

    • font_name: string

      the name of the font for the footer text, or %NULL.

    Returns void

  • set_footer_format(separator: boolean, left: string, center: string, right: string): void

  • Sets the font for printing the page header. If %NULL is supplied, the default font (i.e. the one being used for the text) will be used instead.

    font_name should be a string representation of a font description Pango can understand. (e.g. "Monospace 10"). See pango_font_description_from_string() for a description of the format of the string representation.

    This function cannot be called anymore after the first call to the gtk_source_print_compositor_paginate() function.

    Parameters

    • font_name: string

      the name of the font for header text, or %NULL.

    Returns void

  • set_header_format(separator: boolean, left: string, center: string, right: string): void
  • Sets strftime like header format strings, to be printed on the left, center and right of the top of each page. The strings may include strftime(3) codes which will be expanded at print time. A subset of strftime() codes are accepted, see g_date_time_format() for more details on the accepted format specifiers. Additionally the following format specifiers are accepted:

    • #N: the page number
    • #Q: the page count.

    separator specifies if a solid line should be drawn to separate the header from the document text.

    If %NULL is given for any of the three arguments, that particular string will not be printed.

    For the header to be printed, in addition to specifying format strings, you need to enable header printing with gtk_source_print_compositor_set_print_header().

    This function cannot be called anymore after the first call to the gtk_source_print_compositor_paginate() function.

    Parameters

    • print: boolean

      %TRUE if you want the header to be printed.

    Returns void

  • set_print_line_numbers(interval: number): void
  • Sets the interval for printed line numbers. If interval is 0 no numbers will be printed. If greater than 0, a number will be printed every interval lines (i.e. 1 will print all line numbers).

    Maximum accepted value for interval is 100.

    This function cannot be called anymore after the first call to the gtk_source_print_compositor_paginate() function.

    Parameters

    • interval: number

      interval for printed line numbers.

    Returns void

  • set_property(property_name: string, value?: any): void
  • set_right_margin(margin: number, unit: Gtk.Unit): void
  • Sets the right margin used by compositor.

    Parameters

    • margin: number

    • unit: Gtk.Unit

      the units for margin.

    Returns void

  • set_tab_width(width: number): void
  • Sets the width of tabulation in characters for printed text.

    This function cannot be called anymore after the first call to the gtk_source_print_compositor_paginate() function.

    Parameters

    • width: number

      width of tab in characters.

    Returns void

  • set_top_margin(margin: number, unit: Gtk.Unit): void
  • Sets the line wrapping mode for the printed text.

    This function cannot be called anymore after the first call to the gtk_source_print_compositor_paginate() function.

    Parameters

    Returns void

  • steal_data(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

  • 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

  • vfunc_constructed(): void
  • vfunc_dispatch_properties_changed(n_pspecs: number, pspecs: ParamSpec): void
  • vfunc_dispose(): void
  • vfunc_finalize(): void
  • vfunc_get_property(property_id: number, value?: any, pspec?: ParamSpec): 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

    Returns void

  • vfunc_set_property(property_id: number, value?: any, pspec?: ParamSpec): 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

  • 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

    • g_iface: TypeInterface

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

    Returns ParamSpec[]

  • Creates a new print compositor that can be used to print the buffer associated with view. This constructor sets some configuration properties to make the printed output match view as much as possible. The properties set are #GtkSourcePrintCompositor:tab-width, #GtkSourcePrintCompositor:highlight-syntax, #GtkSourcePrintCompositor:wrap-mode, #GtkSourcePrintCompositor:body-font-name and #GtkSourcePrintCompositor:print-line-numbers.

    Parameters

    • view: GtkSource.View

      a #GtkSourceView to get configuration from.

    Returns GtkSource.PrintCompositor

  • 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
