Defining a Graphic Model for Links

Gantt > Using the Gantt Chart Through Examples > Defining a Graphic Model for Links

To represent links, the user can also define a graphic model. To set the link graphic model, use the following method as indicated, after having defined the model:

gantt->setLinkGraphicModel(CreateDoubleLinkGraphicModel(display));

In the month example, a new class (DoubleLink class) is defined for a specific kind of link and this new class is used as the Gantt link model.

This model is the result of the local function CreateDoubleLinkGraphicModel:

// --------------------------------------------------------------------------

IlvGraphic*

CreateDoubleLinkGraphicModel(IlvDisplay* display)

{

IlvColor* red = display->getColor("red");

IlvColor* black = display->getColor("black");

IlvPalette* palette = display->getPalette(black, red);

palette->lock();

IlvGraphic* model = new DoubleLink(display, IlTrue, 0,0, palette);

palette->unLock();

return model;

}
