WindowPattern.WindowPatternInformation.CanMaximize 속성

정의

네임스페이스:

System.Windows.Automation

어셈블리:

UIAutomationClient.dll

AutomationElement가 최대화될 수 있는지 여부를 지정하는 값을 가져옵니다.

public:
 property bool CanMaximize { bool get(); };

public bool CanMaximize { get; }

member this.CanMaximize : bool

Public ReadOnly Property CanMaximize As Boolean

속성 값

Boolean

AutomationElement를 최대화할 수 있으면 true이고, 그렇지 않으면 false입니다.

예제

다음 예제에서는 WindowPattern 컨트롤 패턴에서 가져온를 AutomationElement 는 이후에의 표시 상태를 지정 하는 데 사용 됩니다는 AutomationElement합니다.
