Örnekler

Aşağıdaki örnekte yönteminin nasıl kullanılacağı gösterilmektedir GetStrokeCaps . Bu örneği çalıştırmak için kodu bir Windows Formuna yapıştırın. Formun Paint olayını işleyip formun Paint olay işleme yönteminden çağrısı DrawCaps yapın ve olarak geçirin ePaintEventArgs.

    GraphicsPath hPath = new GraphicsPath();

    // Create the outline for our custom end cap.

    hPath.AddLine(new Point(5, 1), new Point(3, 1));

    // Construct the hook-shaped end cap.
    CustomLineCap HookCap = new CustomLineCap(null, hPath);

    // Set the start cap and end cap of the HookCap to be rounded.
    HookCap.SetStrokeCaps(LineCap.Round, LineCap.Round);

    // Create a pen and set end custom start and end
    // caps to the hook cap.
    Pen customCapPen = new Pen(Color.Black, 5);
    customCapPen.CustomStartCap = HookCap;
    customCapPen.CustomEndCap = HookCap;

    // the hook cap.
