XREFRESH(1) MachTen Programmer’s Manual XREFRESH(1)
xrefresh - refresh all or part of an X screen
xrefresh [-option ...]
Xrefresh is a simple X program that causes all or part of
your screen to be repainted. This is useful when system
messages have messed up your screen. Xrefresh maps a win-
dow on top of the desired area of the screen and then
immediately unmaps it, causing refresh events to be sent
to all applications. By default, a window with no back-
ground is used, causing all applications to repaint
‘‘smoothly.’’ However, the various options can be used to
indicate that a solid background (of any color) or the
root window background should be used instead.
-white Use a white background. The screen just appears
to flash quickly, and then repaint.
-black Use a black background
(in effect, turning off
all of the electron guns to the tube). This can
be somewhat disorienting as everything goes
black for a moment.
Use a solid background of the specified color.
-root Use the root window background.
-none This is the default. All
of the windows simply
Specifies the portion of the screen to be
