ToolStripManager prend en charge ToolStriples tâches liées pour des applications entières, telles que la fusion, les paramètres et les options du convertisseur. La méthode surchargée Merge combine des ToolStrip contrôles entre eux, et la méthode surchargée annule RevertMerge une opération de fusion.
Utilisez la ToolStripRenderer classe avec la ToolStripManager classe pour obtenir encore plus de contrôle et de personnalisation sur le style de peinture et de disposition.
