.. currentmodule:: gi.repository.Gio



.. data:: DBUS_METHOD_INVOCATION_HANDLED
   :value: True

   The value returned by handlers of the signals generated by
   the ``gdbus-codegen`` tool to indicate that a method call has been
   handled by an implementation. It is equal to :const:`True`, but using
   this macro is sometimes more readable.

   In code that needs to be backwards-compatible with older GLib,
   use :const:`True` instead, often written like this:


   .. code-block::
       :dedent:

         g_dbus_method_invocation_return_error (invocation, ...);
         return TRUE;    // handled







.. data:: DBUS_METHOD_INVOCATION_UNHANDLED
   :value: False

   The value returned by handlers of the signals generated by
   the ``gdbus-codegen`` tool to indicate that a method call has not been
   handled by an implementation. It is equal to :const:`False`, but using
   this macro is sometimes more readable.

   In code that needs to be backwards-compatible with older GLib,
   use :const:`False` instead.

   "(invalid unicode)" if the filename was in an invalid encoding).

   Corresponding :obj:`~gi.repository.Gio.FileAttributeType` is :const:`~gi.repository.Gio.FileAttributeType.STRING`.







.. data:: FILE_ATTRIBUTE_STANDARD_FAST_CONTENT_TYPE
   :value: standard::fast-content-type

   A key in the "standard" namespace for getting the fast content type.

   regular content type.

   Corresponding :obj:`~gi.repository.Gio.FileAttributeType` is :const:`~gi.repository.Gio.FileAttributeType.STRING`.







.. data:: FILE_ATTRIBUTE_STANDARD_ICON
   :value: standard::icon

.. data:: FILE_ATTRIBUTE_STANDARD_IS_SYMLINK
   :value: standard::is-symlink

   A key in the "standard" namespace for checking if the file is a symlink.
   Typically the actual type is something else, if we followed the symlink
   to get the type.

   On Windows NTFS mountpoints are considered to be symlinks as well.

   Corresponding :obj:`~gi.repository.Gio.FileAttributeType` is :const:`~gi.repository.Gio.FileAttributeType.BOOLEAN`.







.. data:: FILE_ATTRIBUTE_STANDARD_IS_VIRTUAL
   :value: standard::is-virtual

   Corresponding :obj:`~gi.repository.Gio.FileAttributeType` is :const:`~gi.repository.Gio.FileAttributeType.BOOLEAN`.







.. data:: FILE_ATTRIBUTE_STANDARD_NAME
   :value: standard::name

   A key in the "standard" namespace for getting the name of the file.

   The name is the on-disk filename which may not be in any known encoding,
   and can thus not be generally displayed as is. It is guaranteed to be set on
   every file.

   Use :const:`~gi.repository.Gio.FILE_ATTRIBUTE_STANDARD_DISPLAY_NAME` if you need to display the
   name in a user interface.

   Corresponding :obj:`~gi.repository.Gio.FileAttributeType` is :const:`~gi.repository.Gio.FileAttributeType.BYTE_STRING`.







.. data:: FILE_ATTRIBUTE_STANDARD_SIZE
   :value: standard::size

   A key in the "standard" namespace for setting the sort order of a file.

   Corresponding :obj:`~gi.repository.Gio.FileAttributeType` is :const:`~gi.repository.Gio.FileAttributeType.INT32`.

   An example use would be in file managers, which would use this key
   to set the order files are displayed. Files with smaller sort order
   should be sorted first, and files without sort order as if sort order
   was zero.







.. data:: FILE_ATTRIBUTE_STANDARD_SYMBOLIC_ICON
   :value: standard::symbolic-icon

   A key in the "standard" namespace for getting the symbolic icon for the file.
