elisp: Layout Parameters
28.4.3.4 Layout Parameters
..........................
These frame parameters enable or disable various parts of the frame, or
control their sizes.
‘border-width’
The width in pixels of the frame’s border.
‘internal-border-width’
The distance in pixels between text (or fringe) and the frame’s
border.
‘vertical-scroll-bars’
Whether the frame has scroll bars for vertical scrolling, and which
side of the frame they should be on. The possible values are
‘left’, ‘right’, and ‘nil’ for no scroll bars.
‘horizontal-scroll-bars’
Whether the frame has scroll bars for horizontal scrolling (‘t’ and
‘bottom’ mean yes, ‘nil’ means no).
‘scroll-bar-width’
The width of vertical scroll bars, in pixels, or ‘nil’ meaning to
use the default width.
‘scroll-bar-height’
The height of horizontal scroll bars, in pixels, or ‘nil’ meaning
to use the default height.
‘left-fringe’
‘right-fringe’
The default width of the left and right fringes of windows in this
frame (Fringes). If either of these is zero, that
effectively removes the corresponding fringe.
When you use ‘frame-parameter’ to query the value of either of
these two frame parameters, the return value is always an integer.
When using ‘set-frame-parameter’, passing a ‘nil’ value imposes an
actual default value of 8 pixels.
‘right-divider-width’
The width (thickness) reserved for the right divider (Window
Dividers) of any window on the frame, in pixels. A value of zero
means to not draw right dividers.
‘bottom-divider-width’
The width (thickness) reserved for the bottom divider (Window
Dividers) of any window on the frame, in pixels. A value of zero
means to not draw bottom dividers.
‘menu-bar-lines’
The number of lines to allocate at the top of the frame for a menu
bar. The default is 1 if Menu Bar mode is enabled, and 0
otherwise. (emacs)Menu Bars.
‘tool-bar-lines’
The number of lines to use for the tool bar. The default is 1 if
Tool Bar mode is enabled, and 0 otherwise. (emacs)Tool
Bars.
‘tool-bar-position’
The position of the tool bar. Currently only for the GTK tool bar.
Value can be one of ‘top’, ‘bottom’ ‘left’, ‘right’. The default
is ‘top’.
‘line-spacing’
Additional space to leave below each text line, in pixels (a
positive integer). Line Height, for more information.
