[PATCH 2/7] perf gtk/annotate: Support multiple event annotation

From: Namhyung Kim
Date: Thu Feb 07 2013 - 04:02:38 EST


From: Namhyung Kim <namhyung.kim@xxxxxxx>

Show multiple annotation result for each evsel. Each result
represents the most frquently sampled symbol/function for the evsel
and it will be shown in a tab window.

For this add a reference to main container (notebook) to the pgctx.
At the first call to annotate browser, hist_entry__find_annotations()
will setup a new browser, and next calls will add new tabs to the
browser. But it requires final perf_gtk__show_annotations() to start
processing GUI events.
