Hi, I will answer on list too.

...

I would like to know if your application class is related only to console applications or is it a generic class that could be implemented also as a gui::application?

It is generic. But now we don't provide any specific support to GUI, you can for sample use it with QT, to do this you need use "common mode".

I'm trying to write a cross platform header only gui library, so I wonder if I should use it (hoping it's a header only library too) or have my own different gui::application class. http://www.dokfile.com/appbeta4/docs/libs/application/doc/html/boost_applica tion/f_a_q_.html#boost_application.f_a_q_.can_i_build_another_application_mo de__what_is_needed_

Well, you can build a application mode that will use your GUI lib, e.g. application::gui use application::common as model. But we have some problem here! 1. Boost.Application is not a boost library yet! (have no support od boost.org) , and it is in working progress status. Things can change! 2. Boost.Application is header only, but have some dependencies that are not header only. http://www.dokfile.com/appbeta4/docs/libs/application/doc/html/boost_applica tion/dependencies.html PS. If you think that this library is interesting to boost, please post on boost.devel, that you have interest on it. http://news.gmane.org/gmane.comp.lib.boost.devel Hope this helps in your decision. If you have any other questions, let me know! -- Renato Forti
