[José Roca]

The following example creates a Pen object, sets the line join style, and draws a rectangle. The code then resets the line join style and draws a second rectangle.

VOID Example_SetLineJoin(HDC hdc)
{
   Graphics graphics(hdc);

   // Create a pen.
   Pen pen(Color(255, 0, 0, 255), 15);

   // Set the join style, and draw a rectangle.
   pen.SetLineJoin(LineJoinRound);
   graphics.DrawRectangle(&pen, 20, 20, 150, 100);

   // Reset the join style, and draw a second rectangle.
   pen.SetLineJoin(LineJoinBevel);
   graphics.DrawRectangle(&pen, 200, 20, 150, 100);
