This changes tui_gen_win_info::handle to be a specialization of unique_ptr. This is perhaps mildly uglier in some spots, due to the proliferation of "get"; but on the other hand it cleans up some manual management and it allows for the removal of tui_delete_win. gdb/ChangeLog 2019-10-09 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.h (tui_delete_win): Don't declare. * tui/tui-stack.c (tui_locator_window::rerender): Update. * tui/tui-command.c (tui_cmd_window::resize) (tui_refresh_cmd_win): Update. * tui/tui-win.c (tui_resize_all, tui_set_focus_command): Update. * tui/tui.c (tui_rl_other_window, tui_enable): Update. * tui/tui-data.c (~tui_gen_win_info): Remove. * tui/tui-layout.c (tui_gen_win_info::resize): Update. * tui/tui-io.c (update_cmdwin_start_line, tui_putc, tui_puts) (tui_redisplay_readline, tui_mld_flush) (tui_mld_erase_entire_line, tui_mld_getc, tui_getc): Update. * tui/tui-regs.c (tui_data_window::delete_data_content_windows) (tui_data_window::erase_data_content) (tui_data_item_window::rerender) (tui_data_item_window::refresh_window): Update. * tui/tui-wingeneral.c (tui_gen_win_info::refresh_window) (box_win, tui_gen_win_info::make_window) (tui_gen_win_info::make_visible): Update.
