[C# 실습, 사용자 정의 컨트롤 제작 예광탄] 레코드 코팅

1. 앞에서 작성하였던 RCMachine.cs와 CotingEventArgs.cs 파일로 구성한 클래스 라이브러리를 만듭니다.

2. Windows Forms 앱(.NET Framework) 프로젝트("RCManchine_공장_예광탄")를 생성합니다.

3. 생성한 프로젝트에 사용자 정의 컨트롤(Windows Forms)을 추가합니다. 파일명: RCMachineControl.cs

4. DPanel 클래스를 추가합니다.

   더블 버퍼링이 가능한 패널을 정의한 클래스입니다.

DPanel.cs

namespace RCManchine_공장_예광탄
{
    public class DPanel:System.Windows.Forms.Panel
    {
        public DPanel()
        {
            SetStyle(System.Windows.Forms.ControlStyles.OptimizedDoubleBuffer | 
                System.Windows.Forms.ControlStyles.UserPaint | 
                System.Windows.Forms.ControlStyles.AllPaintingInWmPaint
                , true);
            UpdateStyles();
        }
    }
}

5. RCMachineControl에 자식 컨트롤을 배치합니다.

pn으로 시작하는 컨트롤은 Panel로 배치하세요.

RCMachineControl 자식 컨트롤 배치

6. RCMachineControlDesigner.cs 파일에 가서 InitializeComponent 메서드의 앞쪽 코드 중에 Panel 개체 생성 코드를 DPanel 생성 코드로 수정합니다.

7. RCMachineControl.cs 에 코드를 작성합니다.

- RCMachine 형식 개체를 참조하는 멤버 필드와 이를 설정하고 가져오기할 속성을 정의합니다. 

- RCMachine 개에의 상태에 따라 컨트롤 속성을 변경할 수 있게 구현합니다.

8. Form1.cs 에 RCMachineControl을 배치하고 컨트롤 이름을 rccon이라 지정합니다.

 Form1에 Load이벤트 핸들러를 등록하여 RCMachine 개체 생성 및 rccon에 생성한 개체를 설정하는 코드를 추가합니다.

Form1.cs

using System;
using System.Windows.Forms;
using 콘솔_예광탄;

namespace RCManchine_공장_예광탄
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            RCMachine rc = new RCMachine();
            rc.RArea = 100;
            rc.CoatingLiq = 2;
            rc.CRadius = 3;
            rc.SpinSpeed = 100;
            rc.SourceCnt = 10;
            rccon.RCMachine = rc;
            rc.Start();
        }
    }
}
