Defining Graphic Models for Lines and Nodes

Gantt > Using the Gantt Chart Through Examples > Defining Graphic Models for Lines and Nodes

This code is used to set graphic models to the Gantt objects (lines and nodes):

gantt->setSubNodeGraphicModel(CreateSubNodeGraphicModel(display));

gantt->setLineGraphicModel(CreateLineGraphicModel(display));

In the month example, external functions CreateSubNodeGraphicModel() and CreateLineGraphicModel(), defined in <ILVHOME>/samples/gantt/common/utils.cpp, are used to create the graphic model used for lines as well as for nodes.

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

IlvGraphic*

CreateSubNodeGraphicModel(IlvDisplay* display)

{

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

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

IlvPalette* palette = display->getPalette(khaki, navy);

palette->lock();

IlvGraphic* model = new IlvShadowLabel(display, "", IlvRect(0, 0, 100, 20),

1, IlvBottomRight, palette);

palette->unLock();

RegisterGanttNameProperty(model);

return model;

}

The subnode graphic model used is an IlvShadowLabel object.

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

IlvGraphic*

CreateLineGraphicModel(IlvDisplay* display)

{

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

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

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

palette->lock();

IlvMessageLabel* model = new IlvMessageLabel(display, "",

IlvRect(0, 0, 100, 20), IlvRight, 0, palette);

palette->unLock();

model->setOpaque(IlFalse);

RegisterGanttNameProperty(model);

return model;

}

The line graphic model used is an IlvMessageLabel object.
