参数
示例
下面的代码示例旨在与 Windows 窗体一起使用,它需要 PaintEventArgse
OnPaint 事件对象。 该代码执行以下操作:
创建描述三角形的四个点的数组。
创建路径并添加行数组。
绘制屏幕的路径。
请注意,第一个点后面的每一行都使用上一个点作为起点,新点作为终结点。
private:
void AddLinesExample( PaintEventArgs^ e )
{
// Create a symetrical triangle using an array of points.
array<Point>^ myArray = {Point(30,30),Point(60,60),Point(0,60),Point(30,30)};
//Create a path and add lines.
GraphicsPath^ myPath = gcnew GraphicsPath;
myPath->AddLines( myArray );
// Draw the path to the screen.
Pen^ myPen = gcnew Pen( Color::Black,2.0f );
e->Graphics->DrawPath( myPen, myPath );
}
private void AddLinesExample(PaintEventArgs e)
{
// Create a symmetrical triangle using an array of points.
Point[] myArray =
{
new Point(30,30),
new Point(60,60),
new Point(0,60),
new Point(30,30)
};
//Create a path and add lines.
GraphicsPath myPath = new GraphicsPath();
myPath.AddLines(myArray);
// Draw the path to the screen.
Pen myPen = new Pen(Color.Black, 2);
e.Graphics.DrawPath(myPen, myPath);
}
Public Sub AddLinesExample(ByVal e As PaintEventArgs)
'Create a symmetrical triangle using an array of points.
Dim myArray As Point() = {New Point(30, 30), New Point(60, 60), _
New Point(0, 60), New Point(30, 30)}
Dim myPath As New GraphicsPath
myPath.AddLines(myArray)
' Draw the path to the screen.
Dim myPen As New Pen(Color.Black, 2)
e.Graphics.DrawPath(myPen, myPath)
End Sub
注解
如果图中有上一条线或曲线,则会添加一条线来连接上一段的终点。该线的起点。
points
参数指定终结点数组。 前两行指定第一行。 每个附加点指定其起点是上一行的终结点的线段的终结点。
