예제

다음 코드 예제에서는 사용자 지정 그리기 방법은 ToolTip합니다.The following code example demonstrates how to custom draw the ToolTip. 이 예에서는 만듭니다는 ToolTip 3 연결 Button 컨트롤에 있는 Form.The example creates a ToolTip and associates it to three Button controls located on the Form. 예제에서는 합니다 OwnerDraw 속성을 true로 처리 합니다 Draw 이벤트입니다.The example sets the OwnerDraw property to true and handles the Draw event. Draw 이벤트 처리기는 ToolTip 는 사용자 지정 단추에 따라 다르게 그려집니다를 ToolTip 나타난 것 처럼 표시 되는 DrawToolTipEventArgs.AssociatedControl 속성.In the Draw event handler, the ToolTip is custom drawn differently depending on what button the ToolTip is being displayed for as indicated by the DrawToolTipEventArgs.AssociatedControl property.
