Utilisation de la classe GlobalizationSettings pour des étiquettes personnalisées de sous total et autres étiquettes de graphique circulaire avec JavaScript via C++
Scénarios d’utilisation possibles
Les API Aspose.Cells ont exposé la classe GlobalizationSettings afin de gérer les scénarios où l’utilisateur souhaite utiliser des étiquettes personnalisées pour les sous-totaux dans une feuille de calcul. De plus, la classe GlobalizationSettings peut également être utilisée pour modifier l’étiquette Autre pour le graphique à secteurs lors du rendu de la feuille de calcul ou du graphique.
Introduction à la classe GlobalizationSettings
La classe GlobalizationSettings offre actuellement les 3 méthodes suivantes qui peuvent être surchargées dans une classe personnalisée pour obtenir les étiquettes souhaitées pour les sous-totaux ou pour rendre un texte personnalisé pour l’étiquette Autre d’un graphique à secteurs.
- GlobalizationSettings.totalName(ConsolidationFunction) : Obtient le nom total de la fonction.
- GlobalizationSettings.grandTotalName(ConsolidationFunction) : Obtient le nom du total général de la fonction.
Étiquettes personnalisées pour les sous-totaux
La classe GlobalizationSettings peut être utilisée pour personnaliser les étiquettes de sous-totaux en surchargeant les méthodes GlobalizationSettings.totalName(ConsolidationFunction) & GlobalizationSettings.grandTotalName(ConsolidationFunction) comme démontré ci-après.

Pour injecter des étiquettes personnalisées, il est nécessaire d’assigner la propriété WorkbookSettings.globalizationSettings à une instance de la classe CustomSettings définie ci-dessus avant d’ajouter les sous-totaux à la feuille de calcul.
