The old layout tried to add the search on top of the help view, which didn't really work because of the way that the QWebView rendered: we got garbage after a scroll with the find opened. So now I'v created a QWidget and layed down the QWebView and the search bar vertically. Signed-off-by: Tomaz Canabrava <tomaz.canabrava@intel.com> Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
