what is the best way to change the highlight (focus) color of a blackberry ListField, I have used the drawFocus method it does highlight thing but it's performance too slow to go on with

Code in drawlistrow 

```
Item item = (Item)this.listData.elementAt(this.getSelectedIndex());

    g.drawText (item.getItemNumber(), 2, y, Graphics.LEFT,20);
    g.drawText (item.getDescription(), 25, y, Graphics.LEFT,30);
    g.drawText (item.getItemType(), 60, y, Graphics.LEFT,15);

    g.setColor(0xC4C3C4);
    g.drawLine(2, y, 2, 115);

```
