def Vispa.Gui.ConnectableWidgetOwner.ConnectableWidgetOwner.propagateEventUnderConnectionWidget (   self,
  connection,
  event 
) 
This function propagates an event to one of it's children.

If a connection widget is clicked in an area where it does not draw the connection line, the event should be forwarded to the underlying widget if there is such one.
However the default behavior of Qt is to propagate the event to the connection's parent. This should be an ConnectableWidgetOwner object.
This function is a workaround searching for any child widget at event.pos() which is not the initial connection.
If it finds such a widget a new event with correct position in the new widget's own frame is created and sent to the widget.
This function calls grabMouse() on the found child. The child should make sure releaseMouse() will be called e.g. in mouseReleaseEvent().

Currently supported events: QEvent.MouseButtonPress, QEvent.MouseButtonDblClick.
