ContextNode.IsConfirmed 方法
取得值,這個值表示 ContextNode 物件是否已確認。InkAnalyzer 無法變更節點型別,以及已確認物件的相關筆劃。
命名空間: Microsoft.Ink
組件: Microsoft.Ink.Analysis (在 Microsoft.Ink.Analysis.dll 中)

'宣告
Public Function IsConfirmed ( _
type As ConfirmationType _
) As Boolean
'用途
Dim instance As ContextNode
Dim type As ConfirmationType
Dim returnValue As Boolean
returnValue = instance.IsConfirmed(type)
public bool IsConfirmed(
ConfirmationType type
)
public:
bool IsConfirmed(
ConfirmationType type

public boolean IsConfirmed(

public function IsConfirmed(

) : boolean
參數
- type
型別:Microsoft.Ink.ConfirmationType
要對照檢查的確認型別。
傳回值
型別:System.Boolean
如果節點型別已確認,則為 true,否則為 false。
範例
下列範例會使用 IsConfirmed() 方法來切換 ContextNode 的確認狀態。這個範例是 Panel (英文) (變數名稱為 theNotesPanel) 上 Control.MouseUp (英文) 事件的處理常式,它會透過 InkCollector (變數名稱為 theInkCollector) 收集筆墨。應用程式有 Boolean (英文) (變數名稱為 confirmMode),是由 MenuItem (英文) (變數名稱為 confirmMenuItem) 設定。在「確認」模式中時,使用者按一下文字即可加以確認 (或在節點已確認時關閉確認)。這個範例會將放開滑鼠事件轉換成筆墨座標,並使用 HitTest 和 FindNodesOfType 找出適當的節點。找到節點之後,就會呼叫 Confirm 以切換確認。最後,會使應用程式離開「確認」模式。
