語法

'宣告
Public Sub SetStrokes ( _
    strokes As StrokeCollection _
)
'用途
Dim instance As ContextNode
Dim strokes As StrokeCollection

instance.SetStrokes(strokes)

public void SetStrokes(
    StrokeCollection strokes
)

void SetStrokes(
    StrokeCollection^ strokes

備註

這個方法不會更新 DirtyRegion。

如果筆劃集合中任何指定的筆劃已設定於 InkAnalyzer，則會擲回 ArgumentException。

範例

下列範例是名為 PopulateNode 的方法，它會使用 TreeView 做為文件模型，以顯示如何使用資料 Proxy 儲存和載入 InkAnalyzer 的內容節點樹狀目錄。DocumentNodeData 類別會在每個 TreeViewItem 物件的 Tag 屬性都設定為 DocumentNodeData 物件時，將 ContextNode 資料儲存在文件模型中。

PopulateNode 方法會透過從 InkAnalyzer 物件加入筆劃、屬性資料、註釋型別、子節點和連結，完整地填入 ContextNode 物件。方法會使用 SetStrokes 加入筆劃。資料來自 DocumentNodeData 物件，而該物件是從對應的 TreeViewItem 取得。

  • this[analyzerNode.Id] 是文件模型類別上的索引子 (Indexer)，會將 Guid 對應至 TreeViewItem (在 VB.NET 中為 Me(analyzerNode.Id))。

  • AddLinksToAnalyer 是文件模型類別上的方法，會將連結加入至 ContextNode。

完整填入節點之後，PartiallyPopulated 屬性會設定為 false。如需資料 Proxy 的詳細資訊，請參閱Data Proxy with Ink Analysis。
