public class IlvMakeActivityInteractor
extends IlvGanttSheetInteractor

An IlvMakeActivityInteractor is an interactor that allows you to create an IlvActivity in a Gantt sheet. The interactor can work in one of two modes:

• Ghost mode. When the mouse is dragged, the interactor draws a ghost rectangle instead of creating the activity immediately. The new activity will be created when the mouse button is released.
• Real mode. When the mouse is dragged, the interactor creates the new activity instead of drawing a ghost rectangle. The new activity is reshaped continuously while the mouse is dragged.

If the interactor is used in a Gantt chart, it creates a new activity and adds it to the associated Gantt model. If the interactor is used in a Schedule chart, the interactor creates a reservation.

The interactor uses the activity or reservation factory to create the new activity or reservation. These factories are defined by the class IlvGanttSheet.

To install the interactor, call the method setInteractor of the class IlvGanttSheet.

This interactor only works with an IlvGanttSheet object.
