From b210b3bb1b002f27165325a5edb6ebce3c168e92 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 25 Feb 2011 11:33:31 -0300 Subject: [PATCH] perf ui browser: Introduce ui_browser__show_title Needed because we were only showing the title in ui_browser__show, not in ui_browser__run, and in the run loop we may be calling other browsers that would then change the title, when we go back to the previous browser, we need to redraw the title. We could have done this as the Newt help line, with pop, etc, but I don't think its worth, doing it explicitely, when needed (some browsers may not use the title area at all) seems enough/more flexible.
