Hi,

I just ran into a problem of pfHighlight, it doesn't work at all.
What I'm trying to do is to HighLight an object when the mouse is
inside its bounding box. It's coded inside a C++ class. I'm using
Performer 2.1 on Onyx2IR.

void grabDCS::getInto(void) // highlight object in whatever mode
{
   pfHighlight *hl;
   hl = new pfHighlight;
   pfEnable(PFEN_HIGHLIGHTING);
   // hl->setMode(PFHL_BBOX_LINES);
   hl->setMode(PFHL_LINES | PFHL_LINESPAT);
   hl->setColor(PFHL_FGCOLOR, 1.0f, 0.0f, 0.0f);
   // hl->setColor(PFHL_BGCOLOR, 1.0f, 0.0f, 0.0f);
   hl->apply();
}

void grabDCS::goOut(void) // remove highlight when mouse is outside
{ pfDisable(PFEN_HIGHLIGHTING);
}

Any idea?
Thanks

Liu
