J'utilise ce code pour créer un contrôle d'armature et introduire une bande avec barre d'outils dans la barre d'armature.
Mais lorsque la fenêtre est affichée, je ne peux pas voir la barre d'outils. et quand je vérifie la hauteur de la barre d'armature, dans cette ligne de code: int height = wp.rcNormalPosition.bottom - wp.rcNormalPosition.top;
Je trouve que la hauteur des barres d'armature n'est que de 4 pixels.Création d'un contrôle d'armature et introduction d'une bande avec barre d'outils dans la barre d'armature
