MenuItem.setAttributeValue

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 gio.menu_item.MenuItem.setAttribute for a more convenient way to do the same.
