Using the Gantt Chart Through Examples

In this chapter, we show how to use the Gantt package through concrete examples. C++ sources code is provided to show how to use the API of the Gantt package.

The following sections provide comments on the sample files provided in the <ILVHOME>/samples/gantt/load and <ILVHOME>/samples/gantt/month directories.

To simplify the use of this sample, only the main header and source files will be considered:

include/month.h, src/month.cpp

The month files (found in the <ILVHOME>/samples/gantt/month directory) define the main user interface. The top-level window is a subtype of IlvGadgetContainer.

include/loadgantt.h, src/loadgantt.cpp

The loadgantt files (found in the <ILVHOME>/samples/gantt/load directory) are the description of the LoadGanttChart class, which is the intermediate class between the IlvGanttChart superclass and the MonthGanttChart class described in this section.

include/monthgantt.h, src/monthgantt.cpp

The monthgantt files (found in the <ILVHOME>/samples/gantt/month directory) contain the definition and the declaration of the MonthGanttChart class, a subclass of the IlvGanttChart class.

This example shows some functionalities of the IlvGanttChart class. It covers the following topics:

The Entry Point of the Sample

Subclassing IlvGanttChart

Customizing Gantt Scales

Modifying the Start and End Times

Automatically Updating Scales

Customizing Gantt Chart Grids

Defining Graphic Models for Lines and Nodes

Defining a Graphic Model for Links

Registering Gantt Data Change Hooks
