Placez du contenu non interactif à l’intérieur, fournissez un accessible-name et calculez preferred-width depuis ce contenu. Choisissez ControlWidth.fill pour remplir la ligne.
activated signale une action acceptée ; disabled et busy empêchent son déclenchement. Entrée agit à l’appui, Espace au relâchement et cancel-press() annule un appui en cours.
