From fa70b5d66d6e9de3331f57e434a16bc0eee980a8 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 1 Jul 2014 16:34:42 -0300 Subject: [PATCH] perf ui browser: Allow overriding refresh_dimensions method Some browsers, like the hist_browser, may want to be notified everytime a refresh_dimensions is needed, so that it can reset ui_browser->rows, for instance, or do some other related reaction to screen resizings.
