From 979d2cac1144da6b25334a8572c80cde9662105c Mon Sep 17 00:00:00 2001 From: Wang Nan Date: Mon, 7 Dec 2015 02:35:46 +0000 Subject: [PATCH] perf hists browser: Reset selection when refresh With the following steps: Step 1: perf report Step 2: Use UP/DOWN to select an entry, don't press 'ENTER' Step 3: Use '/' to filter symbols, use a filter which returns empty result Step 4: Press 'ENTER' We see that, even if we have filtered all the symbols (and the main interface is empty), pressing 'ENTER' still selects one symbol. This behavior surprises the user. This patch resets browser->{he_,}selection in hist_browser__refresh() and lets it choose default selection. In this case browser->{he_,}selection keeps NULL so user won't see annotation item in menu.
