Gibt alle Freihandendknoten zurück, bei denen es sich um ContextNodeBase-Objekte handelt, die keine untergeordneten Knoten besitzen.

Namespace: System.Windows.Ink.AnalysisCore
Assembly: IACore (in IACore.dll)

Syntax

'Declaration
Public Function FindLeafNodes As ContextNodeBaseCollection
'Usage
Dim instance As InkAnalyzerBase
Dim returnValue As ContextNodeBaseCollection

returnValue = instance.FindLeafNodes()

public ContextNodeBaseCollection FindLeafNodes()

public:
ContextNodeBaseCollection^ FindLeafNodes()

public ContextNodeBaseCollection FindLeafNodes()

public function FindLeafNodes() : ContextNodeBaseCollection

Rückgabewert

Typ: System.Windows.Ink.AnalysisCore.ContextNodeBaseCollection
Eine ContextNodeBaseCollection, die alle Endknoten enthält.

Beispiele

Im folgenden Beispiel werden alle Endknoten eines InkAnalyzerBase namens theInkAnalyzerBase durchlaufen, und es wird der Knoten mit der niedrigsten Untergrenze gesucht.

' Find the leaf context node that has the lowest bottom bound.
' In the ink coordinates system a higher value is physically lower.
Dim lowest As Integer = Integer.MinValue
Dim lowestNode As System.Windows.Ink.AnalysisCore.ContextNodeBase = Nothing

Dim leafNode As System.Windows.Ink.AnalysisCore.ContextNodeBase
For Each leafNode In theInkAnalyzerBase.FindInkLeafNodes()
    ' Find lowest node. Note, AnalysisRegionBase.GetBounds() returns an
    ' array containing the left, top, right, and bottom bounds in order.
    If leafNode.Location.GetBounds()(3) > lowest Then
        lowestNode = leafNode
        lowest = leafNode.Location.GetBounds()(3)
    End If
Next leafNode

// Find the leaf context node that has the lowest bottom bound.
// In the ink coordinates system a higher value is physically lower.
int lowest = int.MinValue;
System.Windows.Ink.AnalysisCore.ContextNodeBase lowestNode = null;
foreach (System.Windows.Ink.AnalysisCore.ContextNodeBase leafNode
    in theInkAnalyzerBase.FindInkLeafNodes())
{
    // Find lowest node. Note, AnalysisRegionBase.GetBounds() returns an
    // array containing the left, top, right, and bottom bounds in order.
    if (leafNode.Location.GetBounds()[3] > lowest)
    {
        lowestNode = leafNode;
        lowest = leafNode.Location.GetBounds()[3];
    }
}
