public class GanttChartLite<R extends Row<?,?,?>> extends GanttChartBase<R>
A control used to visualize any kind of scheduling data along a timeline. The model data needed by the control consists of rows with activities, links between activities, and layers to group activities together.
The control consists of several children controls:
  • GraphicsBase: shown on the right-hand side to display a graphical representation of the model data
  • Timeline: shown above the graphics view. The timeline itself consists of two child controls.
  • Dateline: displays days, weeks, months, years, etc...
  • Eventline: displays various time markers

Visually the lite Gantt chart is very similar to a regular Gantt chart that is using the display mode GRAPHICS_ONLY. The big difference is that the lite Gantt chart does not create a tree table view and that the rows can be added as a simple list instead of a hierarchy of rows.

The screenshot belows shows the initial appearance of an empty Gantt chart (lite) control.

Gantt Chart Lite Control

Master / Detail Panes

The Gantt chart uses a single MasterDetailPane instance from ControlsFX for the high-level layout. The pane initially displays a property sheet as its detail node. The property sheet is used at development time and can be replaced with any node by calling GanttChartBase.setDetail(Node). The property sheet displays a lot of properties that are used by the controls, the renderers, the system layers to fine-tune the appearance of the control. Many of them can be changed at runtime.

Standalone vs. Multi- / Dual Gantt Chart

A Gantt chart can be used standalone or inside a MultiGanttChartLiteContainer or DualGanttChartLiteContainer. When used in one of these containers the Position of the Gantt chart becomes important. The control can be the first chart, the last chart, the only chart, or a chart somewhere in the middle. A "first" or "only" chart always displays a timeline. A "middle" or "last" displays an (optional) special header (see GanttChartBase.setGraphicsHeader(Node)). The containers are also the reason why the control distinguishes between a timeline (GanttChartBase.getTimeline()) and a master timeline ( GanttChartBase.getMasterTimeline()). The master timeline is the one shown by the "first" chart, while the regular timeline is the one that belongs directly to an individual Gantt chart instance.
