Definition

Ruft einen Wert ab, der angibt, ob das aktuelle AutomationElement-Element minimiert werden kann.

public:
 property bool CanMinimize { bool get(); };
public bool CanMinimize { get; }
member this.CanMinimize : bool
Public ReadOnly Property CanMinimize As Boolean

Eigenschaftswert

Boolean

true, wenn das AutomationElement minimiert werden kann, andernfalls false.

Beispiele

Im folgenden Beispiel wird ein WindowPattern Steuerelementmuster aus einer AutomationElement abgerufen und anschließend verwendet, um den visuellen Zustand des AutomationElementSteuerelements anzugeben.
