From d67f088e084755bdceb4f15bc6e05e309db1eea7 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Sun, 23 May 2010 22:36:51 -0300 Subject: perf report: Support multiple events on the TUI MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The hists__tty_browse_tree function was created with the loop to print all events, and its equivalent, hists__tui_browse_tree, was created in a similar fashion, where it is possible to switch among the multiple events, if present, using TAB to go the next event, and shift+TAB (UNTAB) to go to the previous. The report TUI now shows as the window title the name of the event and a leak was fixed wrt pstacks.
