This page covers editing workflows at a high level. Consult the Guides section for detailed how-to instructions.
How do I edit tasks on the Gantt chart?
Click the Edit button in the Gantt toolbar to enter edit mode. Once in edit mode, you can drag task bars to change dates, resize them to adjust duration, and create dependency links between tasks. All changes are tracked as pending until you explicitly save. Ifalwaysedit is enabled via widget parameters, the Gantt is always in edit mode and no Edit button is shown.
How do I save my changes?
Click the Save button in the toolbar to persist all pending changes to Polarion. The save operation sends all modified tasks and dependency links to the server in a single transaction. A progress indicator appears during the save process. If there are no unsaved changes, the save button has no effect.| Action | How | Notes |
|---|---|---|
| Enter edit mode | Click Edit in toolbar | Not needed if alwaysedit is true |
| Move a task | Drag the task bar horizontally | Changes start and end dates |
| Resize a task | Drag the right edge of the task bar | Changes duration or end date |
| Save changes | Click Save in toolbar | Persists all pending edits to Polarion |
| Undo changes | Use undo in the toolbar | Multi-step undo of date changes and moves |
What is the lightbox editor?
The lightbox is an inline editing dialog that opens when you double-click a task bar or click the edit icon on a task. It provides form fields for editing task properties such as dates, duration, progress, assigned resources, and custom fields. Changes made in the lightbox are applied to the task when you confirm and are included in the next save operation.Can I undo changes before saving?
Yes, Gantt supports multi-step undo and redo for task date changes, moves, and resizes. Use the undo/redo controls to step back through your editing history before saving. Once you save, changes are committed to Polarion and can no longer be undone through the Gantt undo feature.What happens if two users edit the same task simultaneously?
Gantt uses a last-save-wins approach. There is no real-time conflict detection between concurrent editors. If two users modify the same task, the version saved last overwrites previous changes. Coordinate with your team to avoid editing the same work items at the same time.Can I prevent users from editing specific tasks?
Yes, set thereadonly widget parameter to true to make the entire Gantt chart read-only. For more granular control, individual tasks can be set to read-only mode, which prevents drag, resize, and edit operations on those specific tasks while keeping the rest of the chart editable.
Per-task read-only control may be configured through item scripts or task properties. Check the reference documentation for available options.
Does the Gantt toolbar have a fullscreen mode?
Yes, when themaximize widget parameter is set to true, a fullscreen toggle button appears in the toolbar. Clicking it expands the Gantt chart to fill the browser window, providing more screen space for viewing and editing large project schedules.
