下面的代码示例演示了对 ToolStripManager 及其部分成员的调用。

toolStrip1->RenderMode = 
    ToolStripRenderMode::ManagerRenderMode;
ToolStripManager::Renderer = gcnew RedTextRenderer;

toolStrip1.RenderMode = ToolStripRenderMode.ManagerRenderMode;
ToolStripManager.Renderer = new RedTextRenderer();

toolStrip1.RenderMode = ToolStripRenderMode.ManagerRenderMode
ToolStripManager.Renderer = New RedTextRenderer()

注解

ToolStripManager 支持整个应用程序的 ToolStrip 相关任务，例如合并、设置和呈现器选项。 重载 Merge 方法将控件彼此合并 ToolStrip ，重载 RevertMerge 方法撤消合并操作。

将 ToolStripRenderer 类与 类结合使用 ToolStripManager ，以获得对绘制和布局样式的更多控制和可自定义性。
