xrefresh(X)                     19 June 1992                     xrefresh(X)


 Name

    xrefresh - refresh all or part of an X screen

 Syntax

    xrefresh [-option ...]

 Description

    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 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.

 Arguments


    -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 disorient-
                ing as everything goes black for a moment.

    -solid color
                Use a solid background of the specified color.  Try green.

    -root       Use the root window background.

    -none       This is the default.  All of the windows simply repaint.

    -geometry WxH+X+Y
                Specifies the portion of the screen to be repainted; see X().

    -display display
                This  argument  allows  you  to  specify the server and
                screen to refresh; see X(X).

 X defaults

    The xrefresh program uses the routine XGetDefault(3X) to read defaults,
    so its resource names are all capitalized.

    Black, White, Solid, None, Root
            Determines what sort of window background to use.

    Geometry
            Determines the area to refresh.  Not very useful.

 Environment variables


    DISPLAY To get default host and display number.

 Known Limitations

    It should have just one default type for the background.
