C++ (Cpp) DrawTwoLinesExact Examples

Example #1

void
Canvas::DrawButton(PixelRect rc, bool down)
{
  const Pen old_pen = pen;

  Color gray = IsDithered()
    ? (down ? COLOR_BLACK : COLOR_WHITE)
    : COLOR_LIGHT_GRAY;
  DrawFilledRectangle(rc, gray);

  Pen bright(1, IsDithered() ? COLOR_BLACK : LightColor(gray));
  Pen dark(1, IsDithered() ? COLOR_BLACK : DarkColor(gray));

  Select(down ? dark : bright);
  DrawTwoLinesExact(rc.left, rc.bottom - 2, rc.left, rc.top,
                    rc.right - 2, rc.top);
  DrawTwoLinesExact(rc.left + 1, rc.bottom - 3, rc.left + 1, rc.top + 1,
                    rc.right - 3, rc.top + 1);

  Select(down ? bright : dark);
  DrawTwoLinesExact(rc.left + 1, rc.bottom - 1, rc.right - 1, rc.bottom - 1,
                    rc.right - 1, rc.top + 1);
  DrawTwoLinesExact(rc.left + 2, rc.bottom - 2, rc.right - 2, rc.bottom - 2,
                    rc.right - 2, rc.top + 2);

  pen = old_pen;
}
