MouseEventHandler 대리자

폼, 컨트롤 또는 기타 구성 요소의 MouseDown, MouseUp 또는 MouseMove 이벤트를 처리할 메서드를 나타냅니다.

네임스페이스: System.Windows.Forms
어셈블리: System.Windows.Forms(system.windows.forms.dll)

구문

‘선언
Public Delegate Sub MouseEventHandler ( _
    sender As Object, _
    e As MouseEventArgs _
)
‘사용 방법
Dim instance As New MouseEventHandler(AddressOf HandlerMethod)
public delegate void MouseEventHandler (
    Object sender,
    MouseEventArgs e
)
public delegate void MouseEventHandler (
    Object^ sender, 
    MouseEventArgs^ e
)
/** @delegate */
public delegate void MouseEventHandler (
    Object sender, 
    MouseEventArgs e
)
JScript에서는 대리자를 사용할 수 있지만 새로 선언할 수는 없습니다.

매개 변수

  • sender
    이벤트 소스입니다.

설명

MouseEventHandler 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. 대리자로 이벤트를 처리하는 방법에 대한 자세한 내용은 이벤트 및 대리자를 참조하십시오.

예제

다음 코드 예제에서는 여러 마우스 이벤트를 사용하여 Panel에서 마우스의 이동 경로를 그리는 방법을 보여 줍니다. MouseMoveMouseDown 이벤트가 발생하면 각 GraphicsPath에 선 세그먼트가 추가됩니다. 그래픽을 업데이트하기 위해 MouseDownMouseUp 이벤트가 발생할 때마다 Panel에 대해 Invalidate 메서드가 호출됩니다. 또한 MouseWheel 이벤트가 발생할 때 그래픽 경로가 위 또는 아래로 스크롤됩니다. MouseHover 같은 다른 마우스 이벤트도 화면에서 식별됩니다. 또한 SystemInformation 클래스의 마우스에 대한 추가 정보도 화면에 표시됩니다.
