Setting background and font colors for RichTextField, TextField

Question

How do we set the background and font colors in a RichTextField? I tried to override the paint() method in addition to what has been described here, but when I scroll down in, the background gets erased or reset to a white background

In RIM 4.6 and greater you can use Background:

class ExRichTextField extends RichTextField {

 int mTextColor;

 public ExRichTextField(String text, int bgColor, int textColor) {
  super(text);
  mTextColor = textColor;
  Background background = BackgroundFactory
    .createSolidBackground(bgColor);
  setBackground(background);
 }

 protected void paint(Graphics graphics) {
  graphics.setColor(mTextColor);
  super.paint(graphics);
 }
}

For RIM 4.5 and lower use paint event to draw background youreself:

class ExRichTextField extends RichTextField {

 int mTextColor;
 int mBgColor;

 public ExRichTextField(String text, int bgColor, int textColor) {
  super(text);
  mTextColor = textColor;
  mBgColor = bgColor;
 }

 protected void paint(Graphics graphics) {
  graphics.clear();
  graphics.setColor(mBgColor);
  graphics.fillRect(0, 0, getWidth(), getHeight());
  graphics.setColor(mTextColor);
  super.paint(graphics);
 }
}
