Perforce JViews Gantt Sample: Vacation Activity

---

Description

This sample presents a simple data viewer that demonstrates the use of basic JViews Gantt concepts, as well as user-defined activities. It shows the vacation of the personnel as an activity. It shows this data by an activity-oriented Gantt chart synchronized with a resource-oriented Gantt chart. The sample also demonstrates model filtering and user-defined z-ordering of activities.

How to Use the Sample

How to Run the Sample as an Application

This sample can be run as an application. The installation directory contains an executable JAR file, vacation-activities.jar, that allows you to execute the sample with a double click from a file browser. Note that if you are using Internet Explorer, you can open the installation directory and execute the JAR file from the browser. This technique may not work in other Web browsers.

Alternatively, you can run the sample application from the command line. First check that the Ant utility is properly configured. If not, see the instructions on how to configure Ant for Perforce JViews.

Then, go to the installation directory of the sample and type:

ant run

Topics Covered

• Creating user-defined activities.
• Filtering the Gantt data model by using IlvBasicFilterGanttModel and IlvFilter.
• Extending IlvActivitySimpleLayout to customize the z-ordering of activities.
• Computing dates.

Detailed Description

The frame of the sample is composed of two charts:

• An activity-oriented chart that only displays basic activities by filtering the Gantt data model; this chart hides vacation, since it is meaningless in this view.
• A resource-oriented chart that displays activities and vacation taken by the different resources that work on this sample project.

The toolbar at the top of the frame allows you to control the zoom. Zoom-to-fit does not take into account vacation activity because it is excluded from the time interval computation of parent activities. This sample shows how to implement this exclusion.
