我需要能够使用鼠标点击位置绘制多边形。这是我的当前代码:
//the drawshape varible is called when a button is pressed to select use of this tool
if (DrawShape == 4)
{
Point[] pp = new Point[3];
pp[0] = new Point(e.Location.X, e.Location.Y);
pp[1] = new Point(e.Location.X, e.Location.Y);
pp[2] = new Point(e.Location.X, e.Location.Y);
Graphics G = this.CreateGraphics();
G.DrawPolygon(Pens.Black, pp);
}
谢谢
