But looking at your code, I think the way you're using
pfOverride raised some flags in my mind. You may be simply
leaving the override in place and therefore never turning
the highlighting off in the post function.
I'm at the wrong computer to try this out, but I would
instead try:
int
preDrawHighlight(pfTraverser* , void* )
{
pfOverride(PFSTATE_ENHIGHLIGHTING, 0); // added line
pfEnable(PFEN_HIGHLIGHTING);
pfOverride(PFSTATE_ENHIGHLIGHTING, 1);
Global->hl->apply();
return PFTRAV_CONT;
}
int
postDrawHighlight(pfTraverser* , void* )
{
pfOverride(PFSTATE_ENHIGHLIGHTING, 0); // added line
pfDisable(PFEN_HIGHLIGHTING);
pfOverride(PFSTATE_ENHIGHLIGHTING, 1);
return PFTRAV_CONT;
}
