If you just want to reproduce the windows show in that picture: C-x 1 C-x 2 C-x 3 If you want to have automatically a specific windows at the bottom, even when you type C-x 1, or C-x 3 in that bottom window, I would suggest to add code in the window-configuration-change-hook to check the windows and re-arrange them or re-create the bottom window everytime it's needed. (See the function window-tree and window-parameters). Otherwise, you may explore (in emacs sources) the mini-buffer, which stays at the bottom. -- __Pascal Bourguignon__ http://www.informatimago.com/ ^ permalink raw reply [flat|nested] 6+ messages in thread

This code doesn't satisfy "no matter how many windows are there" - it only handles 1 or 2 windows, and also assumes equal sized windows, so may not be of any value. It does allow the number of bottom window lines and bottom window buffer to be spacified. ; window lines seems to include the mode line (setq bottom_window_lines 8) (setq bottom_window_buffer "*scratch*") (defun MakeBottomWindow () (interactive) (let ( (num_windows (length (window-list nil 0 nil))) ) (cond ( (= num_windows 1) (split-window-vertically (- (window-height) bottom_window_lines)) (when (get-buffer bottom_window_buffer) (set-window-buffer (next-window) bottom_window_buffer) ) ) ( (= num_windows 2) (if (FrameHasTwoHorizontalWindows) (BottomWithTwoHorizontalWindows) (BottomWithTwoVerticalWindows) ) ) ( (> num_windows 2) (message "MakeBottomWindow can't handle more than two windows") (beep) ) ) ) ) (defun BottomWithTwoHorizontalWindows () (get-buffer-create " work") (delete-other-windows) (switch-to-buffer " work") (split-window-vertically (- (window-height) bottom_window_lines)) (split-window-horizontally) (set-window-buffer nil leftWindowBuffer) (other-window 1) (set-window-buffer nil rightWindowBuffer) (other-window 1) (when bottom_window_buffer (set-window-buffer nil bottom_window_buffer) (other-window 1) ) (when rightWindowActive (other-window 1) ) (kill-buffer " work") ) (defun BottomWithTwoVerticalWindows () (unless topWindowActive (other-window 1) ) (shrink-window (round (/ bottom_window_lines 2))) (other-window 1) (split-window-vertically (- (window-height)1 bottom_window_lines)) (when bottom_window_buffer (set-window-buffer (next-window) bottom_window_buffer) ) (if topWindowActive (other-window -1) ) ) (defun FrameHasTwoHorizontalWindows () "are there two side by side windows - from window-split-horizontally" (interactive) (setq currentWindow (next-window) ) (setq windowList (window-list nil 0 nil)) (setq window1Coords (window-edges (car windowList))) (setq window2Coords (window-edges (car (cdr windowList)))) (if (/= (length windowList) 2) nil (if (= (car window1Coords) (car window2Coords)) (progn (if (< (nth 1 window1Coords) (nth 1 window2Coords) ) (progn (setq topWindow (car windowList) ) (setq bottomWindow (nth 1 windowList) ) ) (setq bottomWindow (car windowList) ) (setq topWindow (nth 1 windowList) ) ) (if (eq (next-window) topWindow) (setq topWindowActive nil) (setq topWindowActive t) ) nil ) (if (< (car window1Coords) (car window2Coords) ) (progn (setq leftWindow (car windowList) ) (setq rightWindow (car (cdr windowList) ) ) ) (setq leftWindow (car (cdr windowList) ) ) (setq rightWindow (car windowList) ) ) (setq leftWindowBuffer (window-buffer leftWindow) ) (setq rightWindowBuffer (window-buffer rightWindow) ) (if (eq (next-window) leftWindow) (setq rightWindowActive t) (setq rightWindowActive nil) ) t ) ) ) (global-set-key (kbd "<f8>") 'MakeBottomWindow) ^ permalink raw reply [flat|nested] 6+ messages in thread

The following code gets the window-tree, and walks it to build a lisp expression that will delete and re-split windows so that a new window is created at the bottom. It would need to be completed with the saving and restoring of more window parameters, and to be more precise. For example, I note a shift in the position of the vertical splits which must be due to the difference between window-width and what split-window takes as size argument in this case. Also, before deleting and spliting windows, the size should be checked, and windows resized to accomodate the new one. ;;;; -*- mode:emacs-lisp;coding:utf-8 -*- ;;;;************************************************************************** ;;;;FILE: window-pane.el ;;;;LANGUAGE: emacs lisp ;;;;SYSTEM: POSIX ;;;;USER-INTERFACE: NONE ;;;;DESCRIPTION ;;;; ;;;; A sketch for split-bottom. ;;;; ;;;;AUTHORS ;;;; <PJB> Pascal J.
