DESCRIPTION.

Efface un controle du conteneur et supprime sa configuration.

SYNTAXE.

widget.place_forget ( )

widget ⇨ controle quelconque de l'interface [ OBLIGATOIRE ]

.place_forget ( ) ⇨ appel de la méthode [ OBLIGATOIRE ]

REMARQUES.

Après l'appel de la méthode tkinter.place_forget ( ), le controle appelant, widget, n'est plus visible dans son conteneur, mais il reste un enfant de ce conteneur. Il pourra être rendu de nouveau visible, avec la méthode tkinter.place ( ), en lui attribuant une nouvelle configuration, car ses options définis précédemment seront perdues.

EXEMPLE.
