TabControl.GetTabRect(Int32) 메서드

정의

네임스페이스:

System.Windows.Forms

어셈블리:

System.Windows.Forms.dll

이 탭 컨트롤에 지정된 탭에 대한 경계 사각형을 반환합니다.

public:
 System::Drawing::Rectangle GetTabRect(int index);

public System.Drawing.Rectangle GetTabRect (int index);

member this.GetTabRect : int -> System.Drawing.Rectangle

Public Function GetTabRect (index As Integer) As Rectangle

매개 변수

index

Int32

필요한 탭의 인덱스(0부터 시작)입니다.

반환

Rectangle

지정한 탭의 경계를 나타내는 Rectangle입니다.

예외

ArgumentOutOfRangeException

인덱스가 0보다 작은 경우

또는

인덱스가 Count보다 크거나 같은 경우

예제

다음 코드 예제에서는 하나의 TabPage를 사용하여 를 TabControl 만듭니다. 이 예제에서는 메서드를 GetTabRect 사용하여 탭 영역을 나타내는 을 tabPage1 가져옵니다Rectangle. 는 myTabRectRectangle 이벤트에 의해 DrawItem 그려집니다.

이 예제에서는 System.Drawing 및 System.Windows.Forms 네임스페이스를 사용합니다.
