System.Windows.Forms.ControlPaint 클래스의 FillReversibleRectangle 메서드를 이용해서 반전

            Rectangle highLight = this.btn_test.Bounds;
            highLight.Location = this.PointToScreen(this.btn_test.Bounds.Location);

            ControlPaint.FillReversibleRectangle(highLight, Color.Black);

            timer.Tick += new EventHandler(timer_Tick);
            timer.Interval = 500;
        }

        private void Form1_Activated(object sender, EventArgs e)

        }

        private void Form1_Deactivate(object sender, EventArgs e)

    }
}

 

private Timer timer = new Timer();

타이머를 통한 Rectangle 동작은 유지하되,

폼의 활성 / 비활성 상태에 따른 제어를 하도록 코드를 일부 수정하였습니다.

그리고 활성화, 비활성화에대한 이벤트를 추가하여, 타이머를 제어하도록 하였습니다.

 

private void Form1_Activated(object sender, EventArgs e)
{
timer.Start();
}

private void Form1_Deactivate(object sender, EventArgs e)
{
timer.Stop();
}
