.TH XREFRESH 1 "xrefresh 1.1.0" "X Version 11"
.SH NAME
xrefresh - refresh all or part of an X screen
.SH SYNOPSIS
.B "xrefresh"
[-option ...]
.SH DESCRIPTION
.PP
.I 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.
.I Xrefresh
maps a window 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 background 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.
.SH ARGUMENTS
.PP
.TP 10
.B \-white
Use a white background. The screen just appears to flash quickly, and then
repaint.
.PP
.TP 10
.B \-black
Use a black background. This can be somewhat disorienting as everything goes
black for a moment.
.PP
.TP 10
.B \-solid \fIcolor\fP
Use a solid background of the specified color. Try green.
.PP
.TP 10
.B \-root
Use the root window background.
.PP
.TP 10
.B \-none
This is the default. All of the windows simply repaint.
.PP
.TP 10
.B \-geometry \fIWxH+X+Y\fP
Specifies the portion of the screen to be repainted; see \fIX(7)\fP.
.PP
.TP 10
.B \-display \fIdisplay\fP
This argument allows you to specify the server and screen to
refresh; see \fIX(7)\fP.
.PP
.TP 10
.B \-version
This argument prints the program version and exits.
.SH X DEFAULTS
The
.I xrefresh
program uses the routine
.I XGetDefault(3)
to read defaults, so its resource names are all capitalized.
.PP
.TP 8
.B Black\fP, \fBWhite\fP, \fBSolid\fP, \fBNone\fP, \fBRoot\fP
Determines what sort of window background to use.
.PP
.TP 8
.B Geometry
Determines the area to refresh. Not very useful.
.SH ENVIRONMENT
.PP
.TP 8
DISPLAY - To get default host and display number.
.SH SEE ALSO
X(7)
.SH BUGS
.PP
It should have just one default type for the background.
