org.eclipse.nebula.widgets.ganttchart.undoredo.commands.SectionDeleteCommand

All Implemented Interfaces:

IUndoRedoCommand

public class SectionDeleteCommand
extends java.lang.Object
implements IUndoRedoCommand

Represents one GanttSection delete action that can be undone/redone.

Note that this command is not added internally. This is because there is no code that automatically deletes sections from your GanttComposite. You need to create and record this command together with the code that removes the section from your composite.
