Remarques

Si la Orientation propriété a la valeur Horizontal , le contenu enfant forme les lignes horizontales en premier et, si nécessaire, forme des piles verticales de lignes.If the Orientation property is set to Horizontal, child content forms horizontal rows first and if necessary forms vertical stacks of rows. Si la Orientation propriété a la valeur Vertical , le contenu enfant est d’abord positionné dans une colonne verticale et, s’il n’y a pas assez d’espace, l’encapsulage se produit et des colonnes supplémentaires sont ajoutées à la dimension horizontale.If the Orientation property is set to Vertical, child content is first positioned in a vertical column, and if there is not enough space, wrapping occurs and additional columns in the horizontal dimension are added.
