Core::DocChanges
This class notifies the observers about a recompute of the document.
It can also be used to send messages to the Observers:
1. Example:
 
Core::ExecObject* o = ...

docChanges.Why      = Core::DocChanges::MESSAGE_BY_NAME
docChanges.MsgName  = "MsgObjectAdded";
docChanges.Value    = Core::Variant(o);

2. Example:
 
enum DocMessage
{
    MSG_OBJECT_ADDED = 1,
    ...
}
 
Core::ExecObject* o = ...
 
Core::DocChanges docChanges;
docChanges.Why      = Core::DocChanges::MESSAGE_BY_ID
