我目前正在开发一个 Visual Studio 插件(VSPackage),它最终应该能够可视化调用关系。为了代表他们我想用图#库它管理图形(避免重叠边缘等)。
不幸的是,我在运行时在 XAML 中收到以下错误消息:
XamlParseException:该方法或操作未实现。
错误出现在<graph:CallRelationGraphLayout Graph="{Binding RelationGraph}"/>
tag.

我还创建了自己的顶点、边和图形布局类。我的图最终应该表示方法(顶点)之间的调用关系(边)。
MethodVertex.cs
public class MethodVertex
{
public string ID { get; private set; }
public bool IsMale { get; private set; }
public MethodVertex(string id, bool isMale)
{
ID = id;
IsMale = isMale;
}
public override string ToString()
{
return string.Format("{0}-{1}", ID, IsMale);
}
}
RelationEdge.cs
public class RelationEdge : Edge<MethodVertex>
{
public string Id { get; private set; }
public RelationEdge(string id, MethodVertex source, MethodVertex target)
: base(source, target)
{
Id = id;
}
}
调用RelationGraphLayout.cs
public class CallRelationGraphLayout : GraphLayout<MethodVertex, RelationEdge, CallRelationGraph>
{}
CallRelationGraph.cs
public class CallRelationGraph : BidirectionalGraph<MethodVertex, RelationEdge>
{
public CallRelationGraph()
{}
public CallRelationGraph(bool allowParallelEdges)
: base(allowParallelEdges)
{ }
public CallRelationGraph(bool allowParallelEdges, int vertexCapacity)
: base(allowParallelEdges, vertexCapacity)
{}
}
In the 探索工具视图模型我将 RelationGraph 声明如下:
private CallRelationGraph _relationGraph;
public CallRelationGraph RelationGraph
{
get { return _relationGraph; }
set
{
if (value != _relationGraph)
{
_relationGraph = value;
NotifyPropertyChanged("RelationGraph");
}
}
}
public event PropertyChangedEventHandler PropertyChanged;
public void NotifyPropertyChanged(string propertyName)
{
if (PropertyChanged != null)
PropertyChanged(this, new PropertyChangedEventArgs(propertyName));
}
我也许还应该提到的是,有时会显示以下错误,但项目会编译并运行。
GenericArguments[1],“Biocoder.InteractiveExploration.Graph.RelationEdge”,在“GraphSharp.Algorithms.Layout.ILayoutAlgorithm`3[TVertex,TEdge,TGraph]”上违反了类型“TEdge”的约束。
也许它是问题的根源,但到目前为止我忽略了它,因为它编译了并且我做了与此相对应的事情tutorial.
奇怪的是,它实际上可以在使用 Graph# 提供的 DLL 的普通 WPF 应用程序中工作。当我离开图形属性时,错误不会显示,所以我猜它与图形属性有关。关于如何解决这个问题有任何提示吗?
预先非常感谢您!
