Perforce JViews Gantt Sample: Gantt Viewer

Description

This sample presents a Gantt project viewer developed with JViews Gantt and JViews Diagrammer components.

How to Use the Sample

Several views of the currently selected data model are available. The view can be selected with the view selector on the left of the window or with the View menu.

• The Calendar View shows the Monthly Calendar view, IlvMonthView component.
  • Use the vertical scrollbar or mouse wheel to change the month to be viewed.
  • Drag an activity or a milestone in the calendar to update the start and end time. Durations cannot be updated in this view.
  • Use the Control key to toggle selection and the Shift key to select multiple activities or milestones.
• The Gantt View shows the activity-based Gantt chart, IlvGanttChart component.
  • On the left, an IlvJTable object shows the activity properties. The first column of the table shows the hierarchy of activities in the form of a tree. If an activity has child activities, you can click the expand/collapse icon to expand or collapse it. The other columns are used to show more properties of the activities.
  • On the right, the Gantt chart uses an IlvGanttSheet object to visualize the activities. Note that parent activities are rendered differently from child activities.
  • The time scale is displayed at the top of the Gantt sheet.
  • Many operations on the Gantt chart apply to selected activities. The activities can be selected either in the activity table or in the Gantt sheet.
• The Resource Usage View shows the Schedule chart, IlvScheduleChart component synchronized with the Resource Data chart, IlvResourceDataChart component.
  • On the left, an IlvJTable object shows the resource properties (as the activities in the Gantt chart).
  • On the right, the Gantt chart uses an IlvGanttSheet object to visualize the reservations.
  • The time scale is displayed at the top of the Gantt sheet.
  • The IlvResourceDataChart displays the workload for the selected resource below the IlvScheduleChart.
  • Many operations on the Schedule chart apply to selected resources.
• The Task Sheet shows only the IlvJTable object of the IlvGanttChart component.
• The Resource Sheet shows only the IlvJTable object of the IlvScheduleChart component.
• The PERT Diagram uses JViews Diagrammer to display the activity graph of dependencies.
  • Activities are represented as nodes and end-to-start constraints are represented as links.
  • Three specific interactors are enabled when this view is displayed: the selection, the pan, and the magnify interactors.
  • An overview is displayed during panning and scrolling when the sample is run as an application.
  • There are two levels of detail: a low and a high. Switching between them is done automatically, depending on the current zoom level.

How to Run the Sample as an Application

This sample can be run as an application. The installation directory contains an executable JAR file, ganttviewer.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

• Using the JViews Gantt Activity chart IlvGanttChart component.
• Using the JViews Gantt Schedule chart IlvScheduleChart and the IlvResourceDataChart components.
• Visualizing the Gantt data model by using the Monthly Calendar view IlvMonthView component.
• Using JViews Diagrammer symbols, graph layouts, and SDM.

Detailed Description

This sample presents different components in action, including the activity-based Gantt chart, the Resource Data chart, which displays the loading on resources selected in the Schedule chart, and the Monthly Calendar view. If JViews Diagrammer is installed, the sample also demonstrates a PERT chart.
