[PATCH 3/3 v3] Menu: add box style entry
Jean-Christophe PLAGNIOL-VILLARD

Fri Sep 17 09:45:54 EDT 2010
this will allow you to create a box style entry
via C API by specifying the type as
struct menu_entry me = {
.display "test",
.type = MENU_ENTRY_BOX,
.box_state = 1,
.action = action_to_run,
}
and via shell
menu -e -a -m <menu> -c <command> [-R] [-b 0|1] -d <description>
menu -e -a -m <menu> -u submenu -d [-b 0|1] <description>
-b with 0 for not selected and 1 for selected
and -c for the command to run when changing state
