BasicEditField BlackBerry - blackberry

Question

I want a BasicEditField with rounded border and white background fill.
This is my code
public class BasicField extends BasicEditField {
XYEdges padding = new XYEdges(0,0,0,0);
int color = Color.BLACK;
int lineStyle = Border.STYLE_SOLID;
int Width, Height;
Border roundedBorder = BorderFactory.createRoundedBorder(padding, color, lineStyle);
public BasicField()
{
super(BasicEditField.NO_NEWLINE);
//this.setPadding(2, 2, 2, 2);
//this.setBorder(roundedBorder);
}
public int getPreferredWidth()
{
int labelWidth = getFont().getAdvance(getLabel()) - 1;
Width = Graphics.getScreenWidth() -150;
return Width;
}
public int getPreferredHeight()
{
return 10;
}
public void paint(Graphics g) {
int currCol = g.getColor();
g.setBackgroundColor( Color.WHITE );
g.fillRect(0, 0, getPreferredWidth(), getPreferredHeight() );
g.clear();
g.setColor( Color.NAVY );
super.paint( g );
}
protected void layout( int maxWidth, int maxHeight )
{
super.layout( getPreferredWidth(), getPreferredHeight() );
}
}
