From f1b77574f89ca601cf761717302c2dbf65ba9027 Mon Sep 17 00:00:00 2001 From: Marc Mutz Date: Tue, 27 Sep 2016 21:45:18 +0200 Subject: [doc] Fix docs of QLayoutItem::widget() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit QWidget does not inherit QLayoutItem (unlike QLayout and QSpacerItem, which do), so don't claim that in the docs. Added a note. Added cross-references between layout(), widget() and spacerItem().
