BlackBerry - How to draw Custom Focusable Color/Style for a focusable field?

I have custom drawn fields which are focusable. Normally the default focus color is Blue which obviously doesn't match to every theme. So can you 开发者_开发技巧give me efficient or non efficient ideas to change the color of the focus? Thanks

Why don't you use skin or even custom drawing? Also remember to

• check getVisualState() == VISUAL_STATE_FOCUS
• remember to override and supress applyTheme method

class FCheckBoxField extends CheckboxField {

    public FCheckBoxField(String label, boolean value) {
        super(label, value);
    }

    protected void paint(Graphics g) {
        if (getVisualState() == VISUAL_STATE_FOCUS) {
            int c = g.getColor();
            g.setColor(Color.CRIMSON);
            g.fillRect(0, 0, getWidth(), getHeight());
            g.setColor(c);
        }
        super.paint(g);
    }

    protected void applyTheme(Graphics arg0, boolean arg1) {
    }
}
