What I meant by "Java style GUI" is not in terms of L&F, but in terms of
programming the framework. I understand how important having a native L&F is
to the particular OS you are using (implemented using OS components for
native feel): this is one of the goals I am aiming for.
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();
And this will work, creating a window with a button in it's "client" area.
That is, allow the user to:
 create components/widgets using constructors instead of Create functions
 allow "native" components (buttons, etc.) and windowless components (for
 provide a set of "layout managers" that are windowless components
allowing you to specify scrolling panes, splitter panes, grid layouts, flow
layouts, fixed/stretchy layouts and so on -- I personally find using layout
managers easy to produce interfaces rapidly;
 avoid message maps if possible -- I personally don't like message maps
and feel there is a better way to implement event handling. From the
discussions here boost::signal seems to be the way to go, but some effort
needs to be taken to produce a flexible, portable way of handling messages
that can both write generic handlers and OS-specific handlers;
That is what I mean by a Java-style C++ GUI framework.
