Class GanttChartPrinter

java.lang.Object
org.eclipse.nebula.widgets.ganttchart.print.GanttChartPrinter
Direct Known Subclasses:
CompoundGanttChartPrinter
public class GanttChartPrinter
extends java.lang.Object
This class is used to print a GanttChart. For this it will use the already existing functionality of rendering the GanttChart to an image.

There are some configuration parameters that have impact on:

  • The horizontal range to print - If everything should be printed, by default the range from the earliest event start date to the latest event end date (plus possible text) is used. But configuring a period in the ISettings will also take these values into account for calculating the horizontal range.
  • The vertical range to print - If only the selected part should be printed, by default selection means the visible part of the chart horizontally and vertically. This behavior can be modified so that horizontally only the visible part of the chart will be printed but vertically the whole chart gets printed.
  • The name of the print job
  • Whether a footer should be printed or not
  • The name of the page (can be used for localization)
  • The format of the date in the footer
