Examples
The following code example is designed for use with Windows Forms, and it requires PaintEventArgs e
, which is a parameter of the Paint event handler. The code performs the following actions:
Creates a black pen.
Creates an array of seven points for the vertices of the polygon.
Draws the polygon to the screen.
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
Remarks
Every pair of two consecutive points in the array specifies a side of the polygon. In addition, if the last point and the first point of the array do not coincide, they specify the last side of the polygon.
