From 427326a826888b39a38c9f1b497aa981f37b72af Mon Sep 17 00:00:00 2001 From: Tom Tromey Date: Sat, 22 Feb 2020 11:48:26 -0700 Subject: Simplify TUI C-x 2 binding The TUI "C-x 2" binding tries to switch to a different layout based on the current layout. Once user-defined layouts are available, this won't really make sense. I wasn't entirely sure how to handle this. This patch changes the binding to simply cycle through the existing layouts. I considered this a reasonable, though not ideal, compromise. gdb/ChangeLog 2020-02-22 Tom Tromey * tui/tui.c (tui_rl_change_windows): Call tui_next_layout. * tui/tui-layout.h (tui_next_layout): Declare. * tui/tui-layout.c (tui_next_layout): New function.
