GanttLink (Variable type) In french: LienGantt
The GanttLink type is used to define the advanced characteristics of a link between two tasks of a Gantt chart. You can define and change the characteristics of this link using different WLanguage properties. Note: For more details on the declaration of this type of variable and the use of WLanguage properties, see Declaring a variable.
tabLien is array of GanttLink
tabLien = GanttListLink(COL_Gantt, "ID1")
Lien is GanttLink
FOR EACH Lien OF tabLien
Trace("Lié à " + Lien.SourceID)
END
Properties Properties specific to GanttLink variables The following properties can be used to handle a link between two Gantt tasks: | | | | Property name | Type used | Effect |
|---|
| DestinationID | Character string | Identifier of the target task. This identifier corresponds to the ID property defined in the GanttTask variable. | | SourceID | Character string | Identifier of the source task. This identifier corresponds to the ID property defined in the GanttTask variable. | | Type | Integer constant | Type of link. The available types of links are as follows: - tlgStartStart Start-to-start link: the destination task cannot start before the source task has started.
- tlgStartFin Start-to-finish link: the destination task cannot finish before the source task has started (rare case).
- tlgFinADébut (default value): End-to-start link: the destination task cannot start before the source task has finished.
- tlgFinAFin End-to-end link: the destination task cannot end before the source task has finished.
|
Remarks Notes - A link between 2 tasks is represented by an arrow.
- This type of variable:
- An "End to Start" type link is created by default between the two tasks: the task corresponding to the IDSource property must be finished for the IDDestination task can start.
- According to their types, the links are drawn on the start or end borders of the tasks.
Using GanttLink variables GanttLink variables are used by the following functions:
| | | GanttAddLink | Creates an "End to Start" link between two tasks displayed in a Gantt Chart column found in a Table or TreeView Table control. | | GanttDeleteLink | Removes links from a Gantt Chart column in a Table or TreeView Table control. | | GanttListLink | Lists the links in a Gantt Chart column in a Table or TreeView Table control. |

[ + ] The "WD Gantt" example presents an advanced use of the Gantt Chart control. This example is used to create a Gantt chart with tasks, links, cumulative tasks and milestones. The tasks can be edited in a specific window. The created chart can be saved in a file and reloaded thereafter.
