ContextNodeBase.IsConfirmed 方法

取得值，這個值表示 ContextNodeBase 物件是否已確認。InkAnalyzerBase 無法變更節點型別，以及已確認物件的相關筆劃。

命名空間：  System.Windows.Ink.AnalysisCore
組件：  IACore (在 IACore.dll 中)

語法

'宣告
Public Function IsConfirmed ( _
    type As ConfirmationType _
) As Boolean
'用途
Dim instance As ContextNodeBase
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(
    ConfirmationType type
)

public function IsConfirmed(
    type : ConfirmationType
) : boolean

參數

• type
  型別：System.Windows.Ink.AnalysisCore.ConfirmationType
  ConfirmationType。

傳回值

型別：System.Boolean
如果節點型別已確認，則為 true，否則為 false。

備註

這個值是由 Confirm 方法所設定。

範例

下列範例是 PaneltheNotesPanel 上 MouseUp 事件的事件處理常式，會透過名為 theInkCollector 的 InkCollector 收集筆墨。應用程式具有名為 confirmMode 的 Boolean 值，該值是由名為 confirmMenuItem 的 MenuItem 所設定。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。範例中會使用 HitTest 和 FindNodesOfType 以尋找適合的節點。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。
