示例
下面的代码示例设计用于 Windows 窗体,它需要 PaintEventArgse
,这是 Paint 事件处理程序的参数。 该代码执行以下操作:
创建黑色笔。
创建线条段点数组。
将连接的线条段绘制到屏幕。
public:
void DrawLinesPoint( PaintEventArgs^ e )
{
// Create pen.
Pen^ pen = gcnew Pen( Color::Black,3.0f );
// Create array of points that define lines to draw.
array<Point>^ points = {Point(10,10),Point(10,100),Point(200,50),Point(250,300)};
//Draw lines to screen.
e->Graphics->DrawLines( pen, points );
}
public void DrawLinesPoint(PaintEventArgs e)
{
// Create pen.
Pen pen = new Pen(Color.Black, 3);
// Create array of points that define lines to draw.
Point[] points =
{
new Point(10, 10),
new Point(10, 100),
new Point(200, 50),
new Point(250, 300)
};
//Draw lines to screen.
e.Graphics.DrawLines(pen, points);
}
Public Sub DrawLinesPoint(ByVal e As PaintEventArgs)
' Create pen.
Dim blackPen As New Pen(Color.Black, 3)
' Create array of points that define lines to draw.
Dim points As Point() = {New Point(10, 10), New Point(10, 100), _
New Point(200, 50), New Point(250, 300)}
'Draw lines to screen.
e.Graphics.DrawLines(blackPen, points)
End Sub
注解
此方法绘制连接结束点数组的一系列线条。 数组中的前两个点指定第一行。 每个附加点指定一个线段的终点,其起点是上一行段的终点。
