Example

A basic sample Java™ application, CriticalPathExample.java, illustrates the critical path capabilities of the Rogue Wave® JViews Gantt. Open the sample index file found at:

<installdir>/jviews-gantt/samples/criticalPath.

The instructions in index.html explain how to run the Critical Path example. The source code of this example can be found in:

<installdir>/jviews-gantt/samples/criticalPath/src/criticalPath.

To analyze the critical path:

1. Create an IlvGanttModelScheduler that will automatically analyze the critical path of a Gantt data model as its activities change:

IlvGanttModel model = ...

IlvGanttModelScheduler scheduler = new IlvGanttModelScheduler(ganttModel);

scheduler.setAutoScheduling(true);

2. Use an IlvGanttModelSchedule to manually analyze the critical path of a Gantt data model in the following way:

IlvGanttModel model = ...

IlvGanttModelScheduler scheduler = new IlvGanttModelScheduler(ganttModel);

scheduler.schedule();

3. It is also possible to use an IlvCriticalPathCalculator instance to manually analyze the critical path:

IlvGanttModel model = ...

IlvCriticalPathCalculator calc = new IlvCriticalPathCalculator(ganttModel);

try {

calc.computeSchedule();

} catch (IlvConstraintCycleException ex)

}
