Drawing Filled Polygon with Border
Draw Filled Triangle with Border
We will create an array of points, then use a brush to draw a filled polygon at the point clicked. Then we will use a pen to draw a border around the triangle.
Add this code to the MouseClick event:
private void Form1_MouseClick(object sender, MouseEventArgs e)
{
// Get the graphics of the form.
Graphics g = this.CreateGraphics();
// Create a green pen.
Pen myPen = new Pen(Color.DarkGreen,3);
// Create a blue brush.
SolidBrush myBrush= new SolidBrush(Color.CornflowerBlue);
// Create 3 points, and make array.
Point pt1 = new Point(e.X-15, e.Y);
Point pt2 = new Point(e.X+15, e.Y);
Point pt3 = new Point(e.X, e.Y + 15);
Point[] points = { pt1, pt2, pt3};
// Fill a triangle using the array of points.
g.FillPolygon(myBrush, points);
// Draw a triangle using the array of points.
g.DrawPolygon(myPen, points);
}
To Do: Experiment! Try drawing other polygons with the center at the point clicked.
