範例
下列程式代碼範例的設計目的是要與 Windows Forms 搭配使用,而且需要 PaintEventArgse
OnPaint 事件物件。 程式代碼會執行下列動作:
建立定義多邊形的點陣列。
建立路徑,並將多邊形新增至路徑。
繪製畫面的路徑。
private:
void AddPolygonExample( PaintEventArgs^ e )
{
// Create an array of points.
array<Point>^ myArray = {Point(23,20),Point(40,10),Point(57,20),Point(50,40),Point(30,40)};
// Create a GraphicsPath object and add a polygon.
GraphicsPath^ myPath = gcnew GraphicsPath;
myPath->AddPolygon( myArray );
// Draw the path to the screen.
Pen^ myPen = gcnew Pen( Color::Black,2.0f );
e->Graphics->DrawPath( myPen, myPath );
}
private void AddPolygonExample(PaintEventArgs e)
{
// Create an array of points.
Point[] myArray =
{
new Point(23, 20),
new Point(40, 10),
new Point(57, 20),
new Point(50, 40),
new Point(30, 40)
};
// Create a GraphicsPath object and add a polygon.
GraphicsPath myPath = new GraphicsPath();
myPath.AddPolygon(myArray);
// Draw the path to the screen.
Pen myPen = new Pen(Color.Black, 2);
e.Graphics.DrawPath(myPen, myPath);
}
Public Sub AddPolygonExample(ByVal e As PaintEventArgs)
' Create an array of points.
Dim myArray As Point() = {New Point(23, 20), New Point(40, 10), _
New Point(57, 20), New Point(50, 40), New Point(30, 40)}
' Create a GraphicsPath object and add a polygon.
Dim myPath As New GraphicsPath
myPath.AddPolygon(myArray)
' Draw the path to the screen.
Dim myPen As New Pen(Color.Black, 2)
e.Graphics.DrawPath(myPen, myPath)
End Sub
備註
points
陣列中的點會指定多邊形的頂點。 如果陣列中的第一個點與最後一個點不同,這兩個點會連線到關閉多邊形。
適用於
AddPolygon(PointF[])
