How to fit a widget exactly to the width of its parent?

Hi,

want to set the width of a button so that it fits exactly into its
parent, a FlowPanel in this case.

I have tried to retrieve the parent's client width and subtracted a
lot of numbers, including margin, padding, border, but the button is
always too wide, causing horiziontal scrollbars to appear.

Here is what I have done:

public void onResize()
{
Element e = getElement();
Style s = e.getStyle ();

int b = getInteger (s.getBorderWidth());
int ml = getInteger (s.getMarginLeft());
int mr = getInteger (s.getMarginRight());
int pl = getInteger (s.getPaddingLeft());
int pr = getInteger (s.getPaddingRight());

int pxs = e.getClientWidth() - ml - mr - pl - pr - 2 * b;

myButton.setWidth(pxs + "px");
}

Please help!
Thanks!

Magnus
