For when we are processing the events and inserting the entries in the browser. Experimentation here: naming "ui_something" we may be treading into creating a TUI/GUI set of routines that can then be implemented in terms of multiple backends. Also the time it takes for adding things to the "browser" takes, visually (I guess I should do some profiling here ;-) ), more time than for processing the events... That means we probably need to create a custom hist_entry browser, so that we reuse the structures we have in place instead of duplicating them in newt. But progress was made and at least we can see something while long files are being loaded, that must be one of UI 101 bullet points :-) Cc: Frédéric Weisbecker <fweisbec@gmail.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Paul Mackerras <paulus@samba.org> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
