Remarks

Retrieving a task

To retrieve a task, you can:

use the "=" operator. In this case, you can get the characteristics of the retrieved task.
use the "<-" operator. In this case, you can dynamically modify the retrieved task.

Case 1: Use of the "="operator .

In this case, you can get the characteristics of the retrieved task.

<Variable name> = GanttGetTask(<Gantt column>, <Identifier>)

For example:

// Récupération d'une tâche
MaTâche is GanttTask
MaTâche = GanttGetTask(COL_Gantt, "ID1")
InfoBuild("Tâche récupérée : %1", MaTâche.Title)

You also have the ability to retrieve a task by using the following syntax:

<Variable name> = <Gantt column>["<Identifier>"]

For example:

MaTâche is GanttTask
MaTâche = COL_Gantt["ID1"]
InfoBuild("Tâche récupérée : %1", MaTâche.Title)

2nd case: Use of the "<-". operator.

In this case, you can dynamically modify the retrieved task.

<Variable name> <- GanttGetTask(<Gantt column>, <Identifier>)

where Identifier is the identifier of the task to retrieve.

For example:

// Modification d'une tâche
MaTâche is GanttTask
MaTâche <- GanttGetTask(COL_Gantt, "ID1")
MaTâche.Progress = 70
MaTâche.ProgressColor = LightGreen

You also have the ability to retrieve a task by using the following syntax:

<Variable name> <- <Gantt column>["<Identifier>"]

For example:

t <-COL_Gantt["ID1"]
t.BackgroundColor = LightBlue
