Unfortunately, if they do this the button // looks way too big in Mozilla. Worse yet, if they do this _and_ set a // fixed width for the button we run into trouble because our focus-rect // border/padding and outer border take up 10px of the horizontal button // space or so; the result is that the text is misaligned, even with the // recentering we do in nsHTMLButtonFrame::Reflow. So to solve this, even // if the whitespace is significant, single leading and trailing _spaces_ // (and not other whitespace) are removed. The proper solution, of // course, is to not have the focus rect painting taking up 6px of // horizontal space. We should do that instead (via XBL form controls or // changing the renderer) and remove this. aLabel.Cut(0, 1); aLabel.Truncate(aLabel.Length() - 1); } return NS_OK; }
