Thus, in Java Swing-style C++, you can do something like:

boost::gui::frame * main = new boost::gui::frame( "My GUI App" ); frame -> set_pane( new boost::gui::button( "PUSH" )); frame -> set_size( 500, 400 ); frame -> show();

boost::gui::message_loop msg; return msg.execute();

How does main get deallocated here?

Oops :)

I am very surprised to see "new" and raw pointers in a library designed from scratch. Manual lifetime management is going to lead to a lot of clutter, memory leaks, and is incompatible with exception handling. A system based on smart pointers like boost::shared_ptr and reference-counted container types is essential IMO.

The library currently uses reference counted types to manage allocated types. I understand the use of smart pointers and agree that it is essential. I was just using this example as a guideline.
