Manage selection and hilight of each node from shape's decomposition

Manage selection and hilight of each node from shape's decomposition
Dmitry Kidyaev 2012/09/15 21:03
Is it possible to manage selection and hilight of shape's decomposited nodes (from parent shape) without create specific AIS objects?
I mean the folowing issue.
Here some code.
AISCtx()->InitDetected();
while (AISCtx()->MoreDetected())
{
const TopoDS_Shape &shp = AISCtx()->DetectedShape(); // posible to get decomposed topo object
// AISCtx()->DetectedInteractive(); - this returns hole shape (not decomposed object)
// here I want to hilight or not the node of decomposition (due to my rules).
AISCtx()->NextDetected();
}

Also I want to manage selection like detection how I described above.

Ohhhhhhhhhhhhhhhhhhh.
Solved the hilight case.
Here is the sample.

AISCtx()->InitDetected();
while (AISCtx()->MoreDetected())
{
          Handle(AIS_InteractiveObject) aisobj = AISCtx()->DetectedInteractive();
          Handle(SelectMgr_EntityOwner) own = AISCtx()->DetectedOwner();
// deside to hilight or not
          own->Hilight(AISCtx()->MainPrsMgr());
          AISCtx()->RecomputePrsOnly(aisobj);
          const TopoDS_Shape &shp = AISCtx()->DetectedShape();
          _onDetectShape(shp);
          AISCtx()->NextDetected();
}
I do not sure that it the prober solution but it seems that it works.
