Hiermee stelt u de limieten in die worden gebruikt voor het starten en beëindigen van regels waaruit deze aangepaste limiet bestaat.

public:
 void SetStrokeCaps(System::Drawing::Drawing2D::LineCap startCap, System::Drawing::Drawing2D::LineCap endCap);
public void SetStrokeCaps(System.Drawing.Drawing2D.LineCap startCap, System.Drawing.Drawing2D.LineCap endCap);

Public Sub SetStrokeCaps (startCap As LineCap, endCap As LineCap)

Parameters

startCap
LineCap

De LineCap opsomming die aan het begin van een regel binnen deze limiet wordt gebruikt.

endCap
LineCap

De LineCap opsomming die aan het einde van een regel binnen deze limiet wordt gebruikt.

Voorbeelden

In het volgende voorbeeld ziet u hoe u de SetStrokeCaps methode gebruikt. Als u dit voorbeeld wilt uitvoeren, plakt u de code in een Windows formulier. De gebeurtenis van het formulier Paint verwerken en aanroepen DrawCaps vanuit de methode voor gebeurtenisafhandeling van het formulier Paint , waarbij deze wordt doorgegeven e als PaintEventArgs.


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);
}
