 function Leadtools.Multimedia.PlayCtrl.EditGraph()

public:
virtual void EditGraph();

This method displays a modal dialog box indicating that the graph has been registered. The current thread is suspended during this time. The toolkit then attempts to invoke the GraphEdit utility from the DirectShow SDK. Use GraphEdit's "Connect" menu option to view the registered graph. When finished, exit GraphEdit, and click on the dialog's OK button to continue program execution.
