Exclamation Fixed width button trick not working correctly...

Please Login to Remove!

I have tested the trick given here
BlackBerry Fixed Width ButtonField (also here ButtonField - Is there an easy way to set the width?)

... plus adding a Style so can be centered
my idea was to make it 30 pixels less than the screen width
so.. I have this
Code:
public class FixedWidthButtonField extends ButtonField{
    private int width;
 
    FixedWidthButtonField( String label, int Width){
        super( label, ButtonField.FIELD_HCENTER);
        width = Width;
    }
 
    public int getPreferredWidth(){
        return width;
    }
}
and in the screen
Code:
...
FixedWidthButtonField _bf = new FixedWidthButtonField("Test", Display.getWidth() - 30);
add(_bf);
...
with this I get the button centered, by the text in it isnt centered!!



Im using JDE 4.5.0
any ideas??

Thanks in advance...

Field.FIELD_HCENTER only centers the Field object within the manager.

To center the text, add DrawStyle.HCENTER to the style parameter.

Thanks Dougsg38p
but your solution doesn't change anything. I'm still seeing the text aligned to the left in the button

Do you think it has something to do with my JDE version?

Thanks for your time.

If it still matters ....
To center the text in the button,
override paint in FixedWidthButtonField with something like:

Font font = Font.getDefaultFont();
int textWidth = font.stringWidth(getLabel());
g.drawText(getLabel(), (width - textWidth) / 2, 0);
