This article describes simple example of using Project Gantt chart using ADF Business components.
Use Case Description
Let us create a simple Project Gantt chart using ADF Business components & try to get the selected tasks details.
Implementation steps
A project Gantt chart is used for project management. The chart lists
tasks vertically and shows the duration of each task as a bar on a
horizontal time line.
To create a basic project gantt chart,we first need to define 2 tables as below:
1)task_table with taskid,task_type,start_date & end_date
2)subtask_table with subtaskid,subtask_type,start_date, end_date & taskid
Now we can create Business components for the above 2 tables .Then we will create new jspx page -projectGantt.jspx
Drop TaskView1 as Gantt->Project:
Select all required columns under tasks & subtasks tabs of 'create Project Gantt chart' dialog.
We have created Project Gantt chart that lists tasks & its subtasks.Now if we need to get all task details selected by the user then define taskSelectionListener for the dvt:projectGantt in jspx source page:
taskSelectionListener="#{test.taskSelectlistener}"
public void taskListener(TaskSelectionEvent taskSelectionEvent) {
// This codes gives all the tasks selected by user
System.out.println("Selected task details +taskSelectionEvent.getTask());
}
Run the above page & note that it shows all details of tasks nodes & expanding these tasks nodes shows its corresponding subtasks details.Now if user selects 2 tasks,we can see that it prints the complete task details for the selected tasks.
