나의 개발 노트

이전 시간에 일/주차/년월 정보의 Header를 구성하는 YearMonthWeekNoDayHeader.cs 파일 설정과 내용을 살펴 보았다. 오늘은 실제 일/주차/년월 정보의 Header를 그리는 YearMonthWeekNoDayHeaderGenerator.cs 파일을 살펴보기로 하자.

실제 WANIGrid의 Header 영역을 직접 생성하는 클래스 중 기본 WANIGrid의 Header를 생성하는 클래스인  DefaultHeaderGenerator.cs를 살펴 보았다.

이번에는 일/주차/년월 Header를 생성하는 YearMonthWeekNoDayHeaderGenerator.cs를 만들어 볼 것이다.

YearMonthWeekNoDayHeaderGenerator클래스는 HeaderGenerator클래스를 상속 받아서 구현한다.

YearMonthWeekNoDayHeaderGenerator클래스에는 고정 컬럼이 있을 경우와 없을 경우의 DrawHeaders라는 메소드외에 몇몇 메소드들을 재정의해서 Header영역을 그리는 부분을 구현해야 한다.

실제 Header 영역에 text를 출력하기 위한 DrawTextUtil이라는 클래스를 추가한다.

DrawTextUtil 클래스는 Header영역의 텍스트를 출력하기 위한 클래스로 헤드 영역의 Rectangle 사이즈에 맞는 폰트 사이즈를 계산해서 적정한 크기의 Header Title을 출력하는 역할을 한다.

추가된 YearMonthWeekNoDayHeaderGenerator 클래스를 반영하기 위해 Grid 클래스(Grid.cs)에서 추가 및 보완해야 할 부분을 살펴보자.

YearMonthWeekNoDayHeaderGenerator 영역에서 헤더 영역의 주차/년월 정보를 그리기 위해서 생성했던 Dictionary 변수를 Grid클래스를 통해서 접근할 수 있도록 변수 및 속성(Property)를 추가한다.

    private Dictionary<int, List> dicWeekDay = null; //주차
    private Dictionary<string, List> dicMonthDay = null; //년월

    public Dictionary<int, List> DicWeekDay
    {
        get { return dicWeekDay; }
        set { dicWeekDay = value; }
    }

    public Dictionary<string, List> DicMonthDay
    {
        get { return dicMonthDay; }
        set { dicMonthDay = value; }
    }

WANIGrid클래스에서 Header 영역을 그리기 위해 호출하는 DrawHeader 메소드의 파라미터를 추가한다.

추가된 파라미터는 고정컬럼을 수정할지/수정을 하지 못하도록 할 것인지를 결정하는 bool 값이다.

고정컬럼이 지정되어져 있을 경우, 고정컬럼에 대한 수정 여부를 넘겨주는 값이다.

    public void DrawHeader(Graphics graphics, Rectangle rect, int clientWidth, int colFixed, bool fixedColEditable)
    {
        if (headerGen != null)
        {
            if (colFixed < 0) colFixed = 0;
            if (colFixed == 0)
            {                    
                headerGen.DrawHeaders(firstVisibleCol, lastVisibleCol, clientWidth, graphics, rect);
            }
            else
            {
                headerGen.DrawHeaders(colFixed, firstVisibleCol, lastVisibleCol, clientWidth, graphics, rect, fixedColEditable);
            }
        }
    }

지금까지는 새로 추가된 HeaderGenerator인 YearMonthWeekNoDayHeaderGenerator클래스에 대해서 살펴 보았다.

다음에는 이렇게 추가한 Header영역의 클래스를 기반으로 WANIGrid클래스(WANIGrid.cs)에서의 추가/보완 사항들을 하나씩 살펴보기로 하자.
