From 281ef544a8476f750b9f378593c42b3e8a0b8788 Mon Sep 17 00:00:00 2001 From: Namhyung Kim Date: Mon, 30 Apr 2012 13:55:08 +0900 Subject: perf ui: Add gtk2 support into setup_browser() Now setup_browser can handle gtk2 front-end so split the TUI code to ui/tui/setup.c in order to remove dependency. To this end, make ui__init/exit global symbols and take an argument. Also split gtk code to ui/gtk/setup.c.
