The following example creates a
GraphicsPath object
path, adds two figures to
path (arcs), closes all figures, and then draws
path.
C++
VOID Example_CloseAllFigures(HDC hdc)
{
Graphics graphics(hdc);
Rect rect1(20, 20, 50, 100);
Rect rect2(40, 40, 50, 100);
GraphicsPath path;
path.AddArc(rect1, 0.0f, 180.0f); // first figure
path.StartFigure();
path.AddArc(rect2, 0.0f, 180.0f); // second figure
path.CloseAllFigures();
// Draw the path.
Pen pen(Color(255, 255, 0, 0));
graphics.DrawPath(&pen, &path);
}

LOCAL hStatus AS LONG
