This section describes low-level functions for examining and setting the contents of windows. See Switching Buffers, for higher-level functions for displaying a specific buffer in a window.
This function returns the buffer that window is displaying. If
window is omitted or nil it defaults to the selected
window. If window is an internal window, this function returns
nil.
This function makes window display buffer-or-name.
window should be a live window; if nil, it defaults to
the selected window. buffer-or-name should be a buffer, or the
name of an existing buffer. This function does not change which
window is selected, nor does it directly change which buffer is
current (see Current Buffer). Its return value is nil.
If window is strongly dedicated to a buffer and buffer-or-name does not specify that buffer, this function signals an error. See Dedicated Windows.
By default, this function resets window’s position, display
margins, fringe widths, and scroll bar settings, based on the local
variables in the specified buffer. However, if the optional argument
keep-margins is non-nil, it leaves the display margins
and fringe widths unchanged.
When writing an application, you should normally use the higher-level
functions described in Switching Buffers, instead of calling
set-window-buffer directly.
This runs window-scroll-functions, followed by
window-configuration-change-hook. See Window Hooks.
This buffer-local variable records the number of times a buffer has been
displayed in a window. It is incremented each time
set-window-buffer is called for the buffer.
This buffer-local variable records the time at which a buffer was last
displayed in a window. The value is nil if the buffer has
never been displayed. It is updated each time
set-window-buffer is called for the buffer, with the value
returned by current-time (see Time of Day).
This function returns the first window displaying buffer-or-name
in the cyclic ordering of windows, starting from the selected window
(see Cyclic Window Ordering). If no such window exists, the
return value is nil.
buffer-or-name should be a buffer or the name of a buffer; if
omitted or nil, it defaults to the current buffer. The
optional argument all-frames specifies which windows to
consider:
t means consider windows on all existing frames.
visible means consider windows on all visible frames.
Note that these meanings differ slightly from those of the
all-frames argument to next-window (see Cyclic Window Ordering). This function may be changed in a future version of Emacs
to eliminate this discrepancy.
This function returns a list of all windows currently displaying
buffer-or-name. buffer-or-name should be a buffer or the
name of an existing buffer. If omitted or nil, it defaults to
the current buffer.
The arguments minibuf and all-frames have the same
meanings as in the function next-window (see Cyclic Window Ordering). Note that the all-frames argument does not
behave exactly like in get-buffer-window.
This command replaces buffer-or-name with some other buffer, in
all windows displaying it. buffer-or-name should be a buffer, or
the name of an existing buffer; if omitted or nil, it defaults to
the current buffer.
The replacement buffer in each window is chosen via
switch-to-prev-buffer (see Window History). Any dedicated
window displaying buffer-or-name is deleted if possible
(see Dedicated Windows). If such a window is the only window on its
frame and there are other frames on the same terminal, the frame is
deleted as well. If the dedicated window is the only window on the only
frame on its terminal, the buffer is replaced anyway.
