When leaf Views (such as LabelView) are rendering they should call into this method. If a highlight is in the given region it will be drawn immediately.
Params:
  • g – Graphics used to draw
  • p0 – starting offset of view
  • p1 – ending offset of view
  • viewBounds – Bounds of View
  • editor – JTextComponent
  • view – View instance being rendered
