I am sorry for disturbing you during holidays, but I faced a problem I have been unable to solve for some hours

It looks like the callbacks injecting works nice, but I receive only one request for it. I tried to debug problem, and the only received callback is from download_signal_log::Start(). It looks like downloading have not started. The code is analogous to the gtk one (in gtk downloading is working fine) . Below is a part of code I am using: boost::shared_ptr<download_update_manager> m(boost::make_shared<download_update_manager>()); download_signal_log *log = new download_signal_log; controller = controllers::create_acquire_download_progress(log, progress_view); using aptitude::util::refcounted_wrapper; cwidget::util::ref_ptr<refcounted_wrapper<update_cache_job_impl> > n_wrapper(new refcounted_wrapper<update_cache_job_impl>(this)); ui_download_manager *uim = new ui_download_manager(m, log, n_wrapper, sigc::ptr_fun(&make_gui_progress), &post_event); uim->start(); The full code with callback injecting is available in this testing commit: http://gitorious.org/aptitude/aptitude/commit/a68a400b764928d60d92c6f3795f85bbbcc66485 Thanks in advance for any suggestions > Other than that, I think you should be set. > > Daniel > -- Regards Piotr Galiszewski _______________________________________________ Aptitude-devel mailing list [email protected] http://lists.alioth.debian.org/mailman/listinfo/aptitude-devel
