Name Property Change Hook
This hook, which is also useful when graphic models are defined for customization, must have the following signature:
typedef void (* IlvGanttSetGraphicName)(IlvGanttAbstractObject* object,
IlvGraphic* model,
IlvGanttObjectType type,
IlvAny arg);
The
object parameter is an instance of the
IlvGanttLine,
IlvGanttNode, or
IlvGanttLink classes. The
model parameter is the graphic object used as a model to create the
IlvGanttAbstractObject object. The
type parameter is one of the values defined by the
IlvGanttObjectType enum, and
arg is additional information (which can be useful, for example, when the
IlvGanttAbstractObject object is an
IlvGanttSubNode object).
typedef enum IlvGanttObjectType {IlvGanttIsLine,
IlvGanttIsNode,
IlvGanttIsLink};
There is a user-defined example in <ILVHOME>/samples/gantt/common/src/utils.cpp:
// --------------------------------------------------------------------------
void
OnGanttObjectNameChanged(IlvGanttAbstractObject* object,
IlvGraphic* graphic,
IlvGanttObjectType type,
IlvAny index)
{
if (graphic->getClassInfo()->isSubtypeOf(IlvMatrix::ClassInfo())) {
if (type == IlvGanttIsLine ) {
IlvMatrix* matrix = (IlvMatrix*)graphic;
IlvAbstractMatrixItem* item;
item = matrix->getItem(0,0);
item->setLabel(object->getName());
item = matrix->getItem(1,0);
char buffer[16];
sprintf(buffer, "%d", ((IlvGanttLine*)object)->getCapacity());
item->setLabel(buffer);
}
} else if(graphic->getClassInfo()->isSubtypeOf
(IlvMessageLabel::ClassInfo())) {
IlvMessageLabel* label = (IlvMessageLabel*)graphic;
label->setLabel(object->getName());
} else if(graphic->getClassInfo()->isSubtypeOf
(IlvShadowLabel::ClassInfo())) {
IlvShadowLabel* label = (IlvShadowLabel*)graphic;
label->setLabel(object->getName());
}
if (type == IlvGanttIsNode ) {
IlvGanttNode* node = (IlvGanttNode*)object;
IlvGanttSubNode* subnode = node->getSubNode(*((IlUShort*)index));
graphic->setNamedProperty(new IlvGanttSubNodeToolTip(subnode));
}
}
This user-defined function of type IlvGanttSetGraphicName will automatically be called in the cases previously mentioned.
