例

GetStrokeCaps メソッドの使用方法を次の例に示します。 この例を実行するには、コードを Windows フォームに貼り付けます。 フォームのイベントを処理し、フォームのPaintイベント処理メソッドから を呼び出しDrawCaps、 としてPaintEventArgs渡しますePaint。


protected void DrawCaps(PaintEventArgs e)
{
    GraphicsPath hPath = new GraphicsPath();

    // Create the outline for our custom end cap.
    hPath.AddLine(new Point(0, 0), new Point(0, 5));
    hPath.AddLine(new Point(0, 5), new Point(5, 1));
    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;

    // Create a second pen using the start and end caps from
    // the hook cap.
    Pen capPen = new Pen(Color.Red, 10);
    LineCap startCap;
    LineCap endCap;
    HookCap.GetStrokeCaps(out startCap, out endCap);
    capPen.StartCap = startCap;
    capPen.EndCap = endCap;

    // Create a line to draw.
    Point[] points = { new Point(100, 100), new Point(200, 50), 
        new Point(250, 300) };

    // Draw the lines.
    e.Graphics.DrawLines(capPen, points);
    e.Graphics.DrawLines(customCapPen, points);
}

Protected Sub DrawCaps(ByVal e As PaintEventArgs)
    Dim hPath As New GraphicsPath()

    ' Create the outline for our custom end cap.
    hPath.AddLine(New Point(0, 0), New Point(0, 5))
    hPath.AddLine(New Point(0, 5), New Point(5, 1))
    hPath.AddLine(New Point(5, 1), New Point(3, 1))

    ' Construct the hook-shaped end cap.
    Dim HookCap As New CustomLineCap(Nothing, hPath)

    ' Set the start cap and end cap of the HookCap to be rounded.

    ' caps to the hook cap.

    ' the hook cap.
    Dim capPen As New Pen(Color.Red, 10)
    Dim startCap As LineCap
    Dim endCap As LineCap
    HookCap.GetStrokeCaps(startCap, endCap)
    capPen.StartCap = startCap
    capPen.EndCap = endCap

    ' Create a line to draw.
    Dim points As Point() = {New Point(100, 100), New Point(200, 50), _
        New Point(250, 300)}

    ' Draw the lines.

    e.Graphics.DrawLines(customCapPen, points)
