      java.awt.Container
          javax.swing.JComponent
              com.ontimize.gantt.chart.GanttChartComponent

All Implemented Interfaces:

java.util.EventListener, java.awt.image.ImageObserver, java.awt.MenuContainer, javax.swing.Scrollable, java.io.Serializable, javax.swing.event.TreeExpansionListener, javax.swing.event.TreeModelListener

public class GanttChartComponent

extends javax.swing.JComponent

implements javax.swing.Scrollable, javax.swing.event.TreeModelListener, javax.swing.event.TreeExpansionListener

This class implements a Gantt Chart representation. All chart representations are managed from here task colors, work packages drawings or date ranges to draw.

Notes:

Render to draw work packages (phases and tasks) is DefaultTaskRenderer, but it is configurable with method setTaskRenderer(TaskRenderer). Moreover, model for tasks is defined by TaskModel class.
