[ image: %./images/dossier.gif nom: "employé sans titre" date-creation: 01-Nov-2003 date-modification: 16-Nov-2003 data-chk: 1 ] ] ou donnee: reduce[ context [ image: %./images/dossier.gif nom: "employé sans titre" date-creation: 01-Nov-2003 date-modification: 16-Nov-2003 data-chk: 1 ] ] * Heigth => hauteur de la ligne détail * action-selection => permet d'indiquer l'action à faire lors de la selection exemple : action-selection [ result-text-area/text: mold record-selected show result-text-area ] * table-colors => permet d'indiquer 3 couleurs : 1: couleur ligne impaire 2: couleur ligne paire 3: couleur de selection si les couleurs sont a none alors la face devient transparente * table-field-edge => permet d'indiquer le edge de chaque field du detail } Version: 0.0.0.1 History: [ 0.0.0.1 {Toujours en construction} ] ] ;fonction pour capter le scroll-line a partir de screen-face evt-scroll: func [ face event /local face-x ][ either (event/type == 'scroll-line) [ if not empty?
