From: Tom Tromey Date: Fri, 12 Jul 2019 00:42:20 +0000 (-0600) Subject: Introduce tui_source_window_base::set_contents method X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=81c82c4b9005acf7865d8a19ee651968e059a848;p=binutils-gdb.git Introduce tui_source_window_base::set_contents method This introduces the tui_source_window_base::set_contents method and implements it in the subclasses. This removes a check of the window type. gdb/ChangeLog 2019-08-16 Tom Tromey * tui/tui-winsource.h (struct tui_source_window_base) : Declare. * tui/tui-winsource.c (tui_source_window_base::update_source_window_as_is): Update. * tui/tui-source.h (struct tui_source_window) : Declare.
