Contoh

Contoh kode berikut dirancang untuk digunakan dengan Formulir Windows, dan memerlukan PaintEventArgse, yang merupakan parameter penanganan Paint aktivitas. Kode melakukan tindakan berikut:

• Membuat pena hitam.

• Membuat array tujuh titik untuk simpul poligon.

• Menggambar poligon ke layar.

public:
   void DrawPolygonPoint( PaintEventArgs^ e )
   {
      // Create pen.
      Pen^ blackPen = gcnew Pen( Color::Black,3.0f );

      // Create points that define polygon.
      Point point1 = Point(50,50);
      Point point2 = Point(100,25);
      Point point3 = Point(200,5);
      Point point4 = Point(250,50);
      Point point5 = Point(300,100);
      Point point6 = Point(350,200);
      Point point7 = Point(250,250);
      array<Point>^ curvePoints = {point1,point2,point3,point4,point5,point6,point7};

      // Draw polygon to screen.
      e->Graphics->DrawPolygon( blackPen, curvePoints );
   }

public void DrawPolygonPoint(PaintEventArgs e)
{
             
    // Create pen.
    Pen blackPen = new Pen(Color.Black, 3);
             
    // Create points that define polygon.
    Point point1 = new Point(50,  50);
    Point point2 = new Point(100,  25);
    Point point3 = new Point(200,   5);
    Point point4 = new Point(250,  50);
    Point point5 = new Point(300, 100);
    Point point6 = new Point(350, 200);
    Point point7 = new Point(250, 250);
    Point[] curvePoints =
             {
                 point1,
                 point2,
                 point3,
                 point4,
                 point5,
                 point6,
                 point7
             };
             
    // Draw polygon to screen.
    e.Graphics.DrawPolygon(blackPen, curvePoints);
}

Public Sub DrawPolygonPoint(ByVal e As PaintEventArgs)

    ' Create pen.
    Dim blackPen As New Pen(Color.Black, 3)

    ' Create points that define polygon.
    Dim point1 As New Point(50, 50)
    Dim point2 As New Point(100, 25)
    Dim point3 As New Point(200, 5)
    Dim point4 As New Point(250, 50)
    Dim point5 As New Point(300, 100)
    Dim point6 As New Point(350, 200)
    Dim point7 As New Point(250, 250)
    Dim curvePoints As Point() = {point1, point2, point3, point4, _
    point5, point6, point7}

    ' Draw polygon to screen.
    e.Graphics.DrawPolygon(blackPen, curvePoints)
End Sub

Keterangan

Setiap pasangan dua titik berturut-turut dalam array menentukan sisi poligon. Selain itu, jika titik terakhir dan titik pertama array tidak bertepatan, mereka menentukan sisi terakhir poligon.
