void Widget::replaceHeaderFooter ( HeaderFooter header,

Replaces the old header (or footer, resp.), or appends the new header or footer, it there is none yet.

Parameters
headerThe header or footer to be used instead of the old one. This parameter must not be zero, or the method will do nothing.
oldHeaderThe header or footer to be removed by the new one. This header or footer will be deleted automatically. If the parameter is omitted, the very first header or footer will be replaced. In case, there was no header and no footer yet, the new header or footer will just be added.
Note
If you want to re-use the old header or footer, call takeHeaderFooter and addHeaderFooter, instead of using replaceHeaderFooter.
