  int c0 = textComponent.getBackground().getRGB();
  int c1 = textComponent.getForeground().getRGB();
  int m = 0xfefefefe;
  int c2 = ((c0 & m) >>> 1) + ((c1 & m) >>> 1);
  
  g.setColor(new Color(c2, true));
  g.setFont(textComponent.getFont().deriveFont(Font.ITALIC));
  
  g.drawString(
    placeholderText,
    textComponent.getComponentOrientation() == ComponentOrientation.RIGHT_TO_LEFT
      ? w - (fm.stringWidth(placeholderText) + ins.left + 2)
      : ins.left + 2,
    fm.getAscent() + 2

  if (r == null) {

  }

  this.x = r.x;
  this.y = r.y;
  this.height = r.height;
  // A value for width was probably set by paint(), which we leave alone.
  // But the first call to damage() precedes the first call to paint(), so
  // in this case we must be prepared to set a valid width, or else
  // paint()
  // will receive a bogus clip area and caret will not get drawn properly.
  if (this.width <= 0) {
    this.width = this.getComponent().getWidth();
  }
  //Calls getComponent().repaint(x, y, width, height) to erase
  this.repaint();
  // previous location of caret. Sometimes one call isn't enough.
  this.repaint();
