BlackBerry - ButtonField with centered Bitmap

Question

I have a class that extends from ButtonField :

class BitmapButtonField extends ButtonField
{
    private Bitmap _bitmap;
    private int _buttonWidth;
    pr         


        

Answer 1

In paint() to define x offset for image there is a code:

int x = (getPreferredWidth() - _bitmap.getWidth()) >> 1;

It is ok, still button can have other size, because of:

protected void layout(int width, int height) 
{
    setExtent(Math.min( width, getPreferredWidth()), 
       Math.min( height, getPreferredHeight()));
}

Try to use

protected void layout(int width, int height) 
{
    setExtent(getPreferredWidth(), getPreferredHeight());
}
