Exemples

L’exemple de code suivant montre comment utiliser la GetPartSize(IDeviceContext, ThemeSizeType) méthode dans un contrôle personnalisé pour obtenir les tailles d’une barre de titre de fenêtre, du bouton Fermer , des bordures et de la poignée de dimensionnement spécifiées par le style visuel. Ces tailles sont utilisées pour calculer les tailles des Rectangle objets utilisés pour dessiner les VisualStyleElement objets qui représentent ces parties de fenêtre. Cet exemple de code fait partie d’un exemple plus large fourni pour la vue d’ensemble de la VisualStyleRenderer classe.

    // by the visual style.
