From 806dda08d685bc5f9ed71dfe8b61f21848d48066 Mon Sep 17 00:00:00 2001 From: Gabriel de Dietrich Date: Fri, 17 Aug 2012 13:23:19 +0200 Subject: Moving .qdoc files under examples/widgets/doc Updated those .qdoc files to refer to the new relative examples emplacement. Images and snippets to be moved later. Also grouped all widgets related examples under widgets.
