From 62c95ae33f64ecf398f490886f026a6132fb1520 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Tue, 1 Jul 2014 11:07:54 -0300 Subject: [PATCH] perf ui browser: Add ->rows to disambiguate from ->height The ui_browser->height is about the whole browser "window", including any header, status lines or any other space needed for some "Yes", "No", etc buttons a descendent browser, like hist_browser, may have. Since the navigation is done mostly on the ui_browser methods, it needs to know how many rows are on the screen, while details about what other components are, say, if a header (that may be composed of multiple lines, etc) is present. Besides this we'll need to add a ui_browser->refresh_dimensions() hook so that browsers like hist_browser can update ->rows in response to screen resizes, this will come in a follow up patch. This patch just adds ->rows and updates it when updating ->height, keeps using ->height for the only other widget that can come with ui_browser, the scrollbar, that goes on using all the height on the rightmost column in the screen, using ->rows for the keyboard navigation needs.
