Last month's Qt DeveloperDays Europe videos are now available, including this one showing continued rapid adoption of C++11.

Using C++11 to Speed Up Your Qt 5 Programs (PDF slides)

Marc Mutz

Qt 5 comes with much-improved support for C++11. This talk will teach you techniques that you can use to make your applications use less memory or execute faster when compiled with a C++11 compiler. The focus is on techniques that will not break compatibility with C++98 compilers. After a look at the present state of C++11 support in Qt 5.0, the talk closes with a look at what we can expect in Qt 5.1.

From the summary slide "C++11 @ QT 5.0":

• constexpr added to many types
• move semantics added to a few types
• initializer_list added to most types
• new few N-ary ctors marked explicit, N >= 2
• = delete used almost ubiquitously
• noexcept added in a few central places
