From d874c059d36fe125c577dde9e980407fbd43beac Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?J=C4=99drzej=20Nowacki?= Date: Tue, 24 Jan 2012 15:42:01 +0100 Subject: Introduce QTypeInfo::sizeOf. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In QMetaType "void" is a regular type, lack of c++ sizeof operator force us to write a template specialization for the type.
