When a user interface event occurs, the WdgTag values for the objects involved are assigned to special system variables (Event.EventTag, Event.FieldTag, Event.MenuItemTag). This information identifies the objects involved in the event. The application program can then translate events into the desired action.
WdgTag defaults to the name of the object.
