Constructors

Properties

$gtype: GType<GLib.Error>
FAILED_RENDERING: number

Rendering is not according to expecations

FAILED_UPDATE: number

An animation could not be updated

IGNORED_ELEMENT: number

An XML element is ignored, but it should not affect rendering (this error code is used for metadata and exension elements)

INVALID_ATTRIBUTE: number

An attribute is invalid (either because it is not part of SVG, or because it is not implemented in GTK, or its value is problematic)

INVALID_ELEMENT: number

An XML element is invalid (either because it is not part of SVG, or because it is in the wrong place, or because it not implemented in GTK)

INVALID_REFERENCE: number

A reference does not point to a suitable element

INVALID_SYNTAX: number

The XML syntax is broken in some way

LIMITS_EXCEEDED: number

An implementation limit has been hit, such as the number of loaded shapes.

MISSING_ATTRIBUTE: number

A required attribute is missing

NOT_IMPLEMENTED: number

The SVG uses features that are not supported by Gtk.Svg. It may be advisable to use a different SVG renderer.

Methods - Inherited from GLib

  • Returns true if error matches domain and code, false otherwise. In particular, when error is null, false will be returned.

    If domain contains a FAILED (or otherwise generic) error code, you should generally not check for it explicitly, but should instead treat any not-explicitly-recognized error code as being equivalent to the FAILED code. This way, if the domain is extended in the future to provide a more specific error code for a certain case, your code will still work.

    Parameters

    • domain: number | (new (...args: any[]) => GLib.Error)

      an error domain

    • code: number

      an error code

    Returns boolean

    whether error has domain and code

  • This function registers an extended GLib.Error domain. error_type_name will be duplicated. Otherwise does the same as g_error_domain_register_static().

    Parameters

    • error_type_name: string

      string to create a GLib.Quark from

    • error_type_private_size: number

      size of the private error data in bytes

    • error_type_init: ErrorInitFunc

      function initializing fields of the private error data

    • error_type_copy: ErrorCopyFunc

      function copying fields of the private error data

    • error_type_clear: ErrorClearFunc

      function freeing fields of the private error data

    Returns number

  • This function registers an extended GLib.Error domain.

    error_type_name should not be freed. error_type_private_size must be greater than 0.

    error_type_init receives an initialized GLib.Error and should then initialize the private data.

    error_type_copy is a function that receives both original and a copy GLib.Error and should copy the fields of the private error data. The standard GLib.Error fields are already handled.

    error_type_clear receives the pointer to the error, and it should free the fields of the private error data. It should not free the struct itself though.

    Normally, it is better to use G_DEFINE_EXTENDED_ERROR(), as it already takes care of passing valid information to this function.

    Parameters

    • error_type_name: string

      static string to create a GLib.Quark from

    • error_type_private_size: number

      size of the private error data in bytes

    • error_type_init: ErrorInitFunc

      function initializing fields of the private error data

    • error_type_copy: ErrorCopyFunc

      function copying fields of the private error data

    • error_type_clear: ErrorClearFunc

      function freeing fields of the private error data

    Returns number
