/*! \class KDGanttViewTaskLink KDGanttViewTaskLink.h
|
|
|
This class represents a link between a number of Gantt chart items.
|
|
|
|
|
|
It always connects source items with target items. Task links can
|
|
|
be grouped into KDGanttViewTaskLinkGroup objects.
|
|
|
If a Gantt view item is deleted, it is removed from the fromList or
|
|
|
from the toList.
|
|
|
If one of the lists becomes empty, the complete task link is deleted
|
|
|
as well.
|
|
|
|
|
|
The task link is deleted by KDGanttViews d'tor.
|
|
|
You may delete the task link yourself, if you do it
|
|
|
_before_ KDGanttViews d'tor is called.
