DockPattern.SetDockPosition(DockPosition) 메서드

정의

네임스페이스:

System.Windows.Automation

어셈블리:

UIAutomationClient.dll

도킹 컨테이너 내 요청된 DockPosition에서 AutomationElement를 도킹합니다.

public:
 void SetDockPosition(System::Windows::Automation::DockPosition dockPosition);

public void SetDockPosition (System.Windows.Automation.DockPosition dockPosition);

member this.SetDockPosition : System.Windows.Automation.DockPosition -> unit

Public Sub SetDockPosition (dockPosition As DockPosition)

매개 변수

dockPosition

DockPosition

도킹 컨테이너의 경계 및 컨테이너 내 다른 요소에 상대적인 도킹 위치입니다.

예외

InvalidOperationException

컨트롤이 요청된 도킹 스타일을 실행할 수 없는 경우.

예제

다음 예제에서는 AutomationElement 가 DockPattern 컨트롤 패턴을 지 원하는 컨트롤을 나타내는 해당 dockPosition 수정 합니다.

설명

도킹 컨테이너는 허용 하는 컨트롤 자식 요소를 가로 또는 세로로 도킹 컨테이너 및 컨테이너 내에서 다른 요소의 경계를 기준으로 합니다.
