Contoh kode berikut menunjukkan panggilan ke ToolStripManager dan beberapa anggotanya.

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

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

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

Keterangan

ToolStripManager mendukung tugas terkait ToolStrip untuk seluruh aplikasi, seperti penggabungan, pengaturan, dan opsi perender. Metode yang kelebihan Merge beban menggabungkan ToolStrip kontrol satu sama lain, dan metode yang kelebihan RevertMerge beban membatalkan operasi penggabungan.

ToolStripRenderer Gunakan kelas dengan ToolStripManager kelas untuk mendapatkan kontrol dan penyesuaian yang lebih besar daripada gaya lukisan dan tata letak.
