A window remains visible on its frame unless you delete it by calling certain functions that delete windows. A deleted window cannot appear on the screen, but continues to exist as a Lisp object until there are no references to it. There is no way to cancel the deletion of a window aside from restoring a saved window configuration (see Window Configurations). Restoring a window configuration also deletes any windows that aren’t part of that configuration.
When you delete a window, the space it took up is given to one adjacent sibling. (In Emacs version 18, the space was divided evenly among all the siblings.)
This function returns nil
if window is deleted, and
t
otherwise.
Warning: Erroneous information or fatal errors may result from using a deleted window as if it were live.
This function removes window from the display. If window is omitted, then the selected window is deleted. If window is the only one on its frame, the frame is deleted as well.
Normally, you cannot delete the last non-minibuffer-only frame (you must
use save-buffers-kill-emacs
or kill-emacs
); an error is
signaled instead. However, if optional second argument force is
non-nil
, you can delete the last frame. (This will automatically
call save-buffers-kill-emacs
.)
This function returns nil
.
When delete-window
is called interactively, the selected window
is deleted.
This function makes window the only window on its frame, by
deleting the other windows in that frame. If window is omitted or
nil
, then the selected window is used by default.
The result is nil
.
This function deletes all windows showing buffer. If there are no windows showing buffer, it does nothing.
delete-windows-on
operates frame by frame. If a frame has
several windows showing different buffers, then those showing
buffer are removed, and the others expand to fill the space. If
all windows in some frame are showing buffer (including the case
where there is only one window), then the frame reverts to having a
single window showing another buffer chosen with other-buffer
.
See The Buffer List.
The argument which-frames controls which frames to operate on:
nil
Delete all windows showing buffer in any frame.
t
Delete only windows showing buffer in the selected frame.
visible
Delete all windows showing buffer in any visible frame.
0
Delete all windows showing buffer in any visible frame.
If it is a frame, delete all windows showing buffer in that frame.
Warning: This is similar to, but not identical to, the meaning
of the which-frames argument to next-window
; the meanings
of nil
and t
are reversed.
The optional argument which-devices further clarifies on which
devices to search for frames as specified by which-frames.
This value is only meaningful if which-frames is not t
.
nil
Consider all devices on the selected console.
Consider only the one device device.
Consider all devices on console.
Consider all devices with device type device-type.
window-system
Consider all devices on window system consoles.
Consider all devices without restriction.
This function always returns nil
.
