When you want to get rid of a window used for displaying a buffer, you
(see Deleting Windows) to remove that window from its frame. If the
buffer is shown on a separate frame, you might want to call
delete-frame (see Deleting Frames) instead. If, on the other
hand, a window has been reused for displaying the buffer, you might
prefer showing the buffer previously shown in that window, by calling the
switch-to-prev-buffer (see Window History).
Finally, you might want to either bury (see The Buffer List) or kill
(see Killing Buffers) the window's buffer.
The following command uses information on how the window for displaying the buffer was obtained in the first place, thus attempting to automate the above decisions for you.
This command quits window and buries its buffer. The argument window must be a live window and defaults to the selected one. With prefix argument kill non-
nil, it kills the buffer instead of burying it. It calls the function
quit-restore-windowdescribed next to deal with the window and its buffer.
This function tries to restore the state of window that existed before its buffer was displayed in it. The optional argument window must be a live window and defaults to the selected one.
If window was created specially for displaying its buffer, this function deletes window provided its frame contains at least one other live window. If window is the only window on its frame and there are other frames on the frame's terminal, the value of the optional argument bury-or-kill determines how to proceed with the window. If bury-or-kill equals
kill, the frame is deleted unconditionally. Otherwise, the fate of the frame is determined by calling
frame-auto-hide-function(see below) with that frame as sole argument.
Otherwise, this function tries to redisplay the buffer previously shown in window. It also tries to restore the window start (see Window Start and End) and point (see Window Point) positions of the previously shown buffer. If, in addition, window's buffer was temporarily resized, this function will also try to restore the original height of window.
The cases described so far require that the buffer shown in window is still the buffer displayed by the last buffer display function for this window. If another buffer has been shown in the meantime, or the buffer previously shown no longer exists, this function calls
switch-to-prev-buffer(see Window History) to show some other buffer instead.
The optional argument bury-or-kill specifes how to deal with window's buffer. The following values are handled:
- This means to not deal with the buffer in any particular way. As a consequence, if window is not deleted, invoking
switch-to-prev-bufferwill usually show the buffer again.
- This means that if window is not deleted, its buffer is moved to the end of window's list of previous buffers, so it's less likely that a future invocation of
switch-to-prev-bufferwill switch to it. Also, it moves the buffer to the end of the frame's buffer list.
- This means that if window is not deleted, its buffer is removed from window's list of previous buffers. Also, it moves the buffer to the end of the frame's buffer list. This value provides the most reliable remedy to not have
switch-to-prev-bufferswitch to this buffer again without killing the buffer.
- This means to kill window's buffer.
quit-restore-windowbases its decisions on information stored in window's
quit-restorewindow parameter (see Window Parameters), and resets that parameter to
nilafter it's done.
The following option specifies how to deal with a frame containing just one window that should be either quit, or whose buffer should be buried.
The function specified by this option is called to automatically hide frames. This function is called with one argument—a frame.
The function specified here is called by
bury-buffer(see The Buffer List) when the selected window is dedicated and shows the buffer to bury. It is also called by
quit-restore-window(see above) when the frame of the window to quit has been specially created for displaying that window's buffer and the buffer is not killed.
The default is to call
iconify-frame(see Visibility of Frames). Alternatively, you may specify either
delete-frame(see Deleting Frames) to remove the frame from its display,
ignoreto leave the frame unchanged, or any other function that can take a frame as its sole argument.
Note that the function specified by this option is called only if the specified frame contains just one live window and there is at least one other frame on the same terminal.
