Is there any way to set some windows non visitable in emacs?
For example, in gdb show-many-windows view, I dont want to switch to local variables window or stack window every time.
C-x o is set to other-window. It is notoriously hard to customize, but here you go: It respects the window parameter 'no-other-window. Your goal will be to do (set-window-parameter gdb-window 'no-other-window t). Now, the only part that remains is to hook us into gud and set those properties on the windows.
A good start is
(defun make-selected-window-unselectable ()
(interactive)
(set-window-parameter (selected-window) 'no-other-window t))
(global-set-key "\M-p" 'make-selected-window-unselectable)
Someone will probably haggle about the name, as the window is not truly unselectable, but it will make do.
