The following example creates a
GraphicsPath object
path, adds two rectangles to
path, and then draws
path.
C++
VOID Example_AddRectangles(HDC hdc)
{
Graphics graphics(hdc);
RectF rects[] = {RectF(20.0f, 20.0f, 100.0f, 50.0f),
RectF(30.0f, 30.0f, 50.0f, 100.0f)};
GraphicsPath path;
path.AddRectangles(rects, 2);
// Draw the path.
Pen pen(Color(255, 255, 0, 0));
graphics.DrawPath(&pen, &path);
}
