[C# Form] 아날로그 디지털시계

아날로그와 디지털 시계를 Form으로 만들어 보겠습니다.

Form을 사용할 때는 GDI+를 사용합니다.

디자인은 위와 같습니다. 메뉴 하나와 타이머 컨트롤을 사용하겠습니다. 또한 그림을 그리기 위한 Panel을 사용했습니다..

소스코드는 다음과 같습니다.

using System;
using System.Drawing;
using System.Windows.Forms;
 
namespace WindowsFormsApplication1
{
    public partial class Form1 : Form
    {
        Graphics g;
        private bool aClock_Flag = false;
        private Point Center;
        private double radius;
        private int hourHand;
        private int minHand;
        private int secHand;
        public Form1()
        {
            InitializeComponent();
            this.Text = "2016 FormClock";
            this.DoubleBuffered = true;
            g = panel1.CreateGraphics();
 
            panel1.Width = 200;
            panel1.Height = 200;
 
            panel1.BackColor = Color.White;
            this.BackColor = Color.White;
            
            aClockSetting();
            TimerSetting();
        }

        {
            timer1.Interval = 1000;     // 1초에 한번씩
            timer1.Tick += Timer1_Tick;
            timer1.Start();
        }

                g.DrawString(time, font1, brush1, new Point(0, 80));
            }

실행화면은 다음과 같습니다.
