5.2 Customizing Window Appearance

Variable: *maxsize-border-width*

The width in pixels given to the borders of windows with maxsize or ratio hints.

Variable: *transient-border-width*

The width in pixels given to the borders of transient or pop-up windows.

Variable: *normal-border-width*

The width in pixels given to the borders of regular windows.

Variable: *window-border-style*

This controls the appearance of the border around windows. valid values are:

:thick

All space within the frame not used by the window is dedicated to the border.

:thin

Only the border width as controlled by *maxsize-border-width* *normal-border-width* and *transient-border-width* is used as the border. The rest is filled with the unfocus color.

:tight

The same as :thin but the border surrounds the window and the wasted space within the frame is not obscured, revealing the background.

:none

Like :tight but no border is ever visible.

After changing this variable you may need to call sync-all-frame-windows to see the change.

Function: set-maxsize-gravity gravity

Set the default gravity for maxsize windows.

Function: set-transient-gravity gravity

Set the default gravity for transient/pop-up windows.

Command: gravity gravity
