From: Tom Tromey Date: Mon, 17 Jun 2019 20:08:44 +0000 (-0600) Subject: Introduce tui_gen_win_info::reset method X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d6ba6a11642cdbec4ce91fefe455920b5c073f60;p=binutils-gdb.git Introduce tui_gen_win_info::reset method This introduces the tui_gen_win_info::reset method and changes various places to use it. This led to the realization that the can_highlight member only needs to be set during construction, so this patch makes that change as well. Finally, init_and_make_win is drastically simplified. gdb/ChangeLog 2019-06-25 Tom Tromey * tui/tui-layout.c (make_command_window): Don't set can_highlight. (show_source_disasm_command): Call the reset method. (show_data): Don't set can_highlight. Call the reset method. (tui_gen_win_info::reset): Rename from init_gen_win_info (init_and_make_win): Simplify. Return tui_gen_win_info. (show_source_or_disasm_and_command): Call the reset method. * tui/tui-data.h (struct tui_gen_win_info) : New method.
