setAttributeValue

open fun setAttributeValue(attribute: String, value: <Error class: unknown class>? = null)

Sets or unsets an attribute on @menu_item.

The attribute to set or unset is specified by @attribute. This can be one of the standard attribute names %G_MENU_ATTRIBUTE_LABEL, %G_MENU_ATTRIBUTE_ACTION, %G_MENU_ATTRIBUTE_TARGET, or a custom attribute name. Attribute names are restricted to lowercase characters, numbers and '-'. Furthermore, the names must begin with a lowercase character, must not end with a '-', and must not contain consecutive dashes.

must consist only of lowercase ASCII characters, digits and '-'.

If @value is non-null then it is used as the new value for the attribute. If @value is null then the attribute is unset. If the @value #GVariant is floating, it is consumed.

See also g_menu_item_set_attribute() for a more convenient way to do the same.
