user interface - 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);
    }
}
