Method
GioMenuItemset_action_and_target
Declaration
void
g_menu_item_set_action_and_target (
GMenuItem* menu_item,
const gchar* action,
const gchar* format_string,
...
)
Description
Sets or unsets the “action” and “target” attributes of menu_item
.
If action
is NULL
then both the “action” and “target” attributes
are unset (and format_string
is ignored along with the positional parameters).
If action
is non-NULL
then the “action” attribute is set.
format_string
is then inspected. If it is non-NULL
then the proper
position parameters are collected to create a GVariant
instance to
use as the target value. If it is NULL
then the positional
parameters are ignored and the “target” attribute is unset.
See also g_menu_item_set_action_and_target_value()
for an equivalent
call that directly accepts a GVariant
. See
g_menu_item_set_detailed_action()
for a more convenient version that
works with string-typed targets.
See also g_menu_item_set_action_and_target_value()
for a
description of the semantics of the action and target attributes.
