Method
GioMenuItemset_attribute

Declaration [src]
void
g_menu_item_set_attribute (
  GMenuItem* menu_item,
  const gchar* attribute,
  const gchar* format_string,
  ...
)
Description [src]
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.
If format_string is non-NULL then the proper position parameters
are collected to create a GVariant instance to use as the attribute
value.  If it is NULL then the positional parameterrs are ignored
and the named attribute is unset.
See also g_menu_item_set_attribute_value() for an equivalent call
that directly accepts a GVariant.
