项目
10/28/2008

返回作为没有子节点的 ContextNodeBase 对象的所有叶节点。

命名空间： System.Windows.Ink.AnalysisCore
程序集： IACore（在 IACore.dll 中）

语法

声明
Public Function FindLeafNodes As ContextNodeBaseCollection
用法
Dim instance As InkAnalyzerBase
Dim returnValue As ContextNodeBaseCollection

returnValue = instance.FindLeafNodes()

public ContextNodeBaseCollection FindLeafNodes()

public:
ContextNodeBaseCollection^ FindLeafNodes()

public ContextNodeBaseCollection FindLeafNodes()

public function FindLeafNodes() : ContextNodeBaseCollection

返回值

类型：System.Windows.Ink.AnalysisCore.ContextNodeBaseCollection
一个包含所有叶节点的 ContextNodeBaseCollection。

示例

下面的示例遍历 InkAnalyzerBase (theInkAnalyzerBase) 的所有叶节点，查找具有最低下限的叶节点。

' 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];
    }
}
