설명

DrawItem 이벤트는 소유자가 그린 StatusBarPanel의 시각적 측면이 변경될 때 발생합니다. StatusBarDrawItemEventArgs는 패널을 그리는 데 사용할 Graphics 개체, 패널을 그릴 Rectangle 개체, 패널 확인 번호, 해당 패널에 대한 상태 정보 그리고 그릴 패널을 지정합니다. DrawItem 이벤트에 대한 이벤트 처리기에서 이 클래스가 제공하는 데이터를 사용하여 응용 프로그램의 StatusBar 컨트롤에 사용자가 그린 패널을 만들 수 있습니다.

예제

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