ScrollEventHandler 대리자
DataGridView, ScrollBar, TrackBar 또는 DataGrid의 Scroll 이벤트를 처리하는 메서드를 나타냅니다.
네임스페이스: System.Windows.Forms
어셈블리: System.Windows.Forms(system.windows.forms.dll)
구문
‘선언
Public Delegate Sub ScrollEventHandler ( _
sender As Object, _
e As ScrollEventArgs _
)
‘사용 방법
Dim instance As New ScrollEventHandler(AddressOf HandlerMethod)
public delegate void ScrollEventHandler (
Object sender,
ScrollEventArgs e
)
public delegate void ScrollEventHandler (
Object^ sender,
ScrollEventArgs^ e
)
/** @delegate */
public delegate void ScrollEventHandler (
Object sender,
ScrollEventArgs e
)
JScript에서는 대리자를 사용할 수 있지만 새로 선언할 수는 없습니다.
매개 변수
- sender
이벤트 소스입니다.
- e
이벤트 데이터가 들어 있는 ScrollEventArgs입니다.
설명
ScrollEventArgs 대리자를 만드는 경우 이벤트를 처리할 메서드를 결정합니다. 이벤트를 이벤트 처리기와 연결하려면 대리자의 인스턴스를 해당 이벤트에 추가합니다. 대리자를 제거하지 않는 경우 이벤트가 발생할 때마다 이벤트 처리기가 호출됩니다. 이벤트 처리기 대리자에 대한 자세한 내용은 이벤트 및 대리자를 참조하십시오.
