StatusBar의 DrawItem 이벤트를 처리할 메서드를 나타냅니다.

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

구문

‘선언
Public Delegate Sub StatusBarDrawItemEventHandler ( _
    sender As Object, _
    sbdevent As StatusBarDrawItemEventArgs _
)
‘사용 방법
Dim instance As New StatusBarDrawItemEventHandler(AddressOf HandlerMethod)

public delegate void StatusBarDrawItemEventHandler (
    Object sender,
    StatusBarDrawItemEventArgs sbdevent
)

public delegate void StatusBarDrawItemEventHandler (
    Object^ sender, 
    StatusBarDrawItemEventArgs^ sbdevent
)

/** @delegate */
public delegate void StatusBarDrawItemEventHandler (
    Object sender, 
    StatusBarDrawItemEventArgs sbdevent
)

JScript에서는 대리자를 사용할 수 있지만 새로 선언할 수는 없습니다.

매개 변수

sender
이벤트 소스입니다.

sbdevent
이벤트 데이터가 들어 있는 StatusBarDrawItemEventArgs입니다.

설명

StatusBarDrawItemEventHandler 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.

예제

다음 코드 예제에서는 StatusBarPanel.Style 속성, StatusBarDrawItemEventHandler 대리자, StatusBarDrawItemEventArgs 클래스, StatusBarPanelStyle 열거형 및 Panel 속성을 사용하는 방법을 보여 줍니다. 이 예제를 실행하려면 폼에 다음 코드를 붙여넣고 폼의 생성자나 Load 이벤트 처리 메서드에서 InitializeStatusBarPanels 메서드를 호출합니다.
