NAME

       FvwmBacker - the FVWM background changer module

SYNOPSIS

       FvwmBacker is spawned by fvwm, so no command line invocation will work.

DESCRIPTION

       The  FvwmBacker  module  provides  functionality  to  change  the background when changing desktops.  Any
       command can be executed to change the backgrounds.  The commands used to change the backgrounds must exit
       after changing the root window, (i.e. 'xv -root zzz.gif' does not, without the  -quit  option)  otherwise
       FvwmBacker will hang.

COPYRIGHTS

       The FvwmBacker module is the original work of Mike Finger.

       Copyright  1994,  Mike  Finger. The author makes no guarantees or warranties of any kind about the use of
       this module.  Use this modules at your own risk.  You may freely use this module or any portion of it for
       any purpose as long as the copyright is kept intact.

INITIALIZATION

       During initialization, FvwmBacker will scan the same configuration file that FVWM used during startup  to
       find the options that pertain to it.  These options are discussed in a later section.

INVOCATION

       FvwmBacker  can be invoked by fvwm during initialization by inserting the line 'Module FvwmBacker' in the
       .fvwmrc file.

       FvwmBacker must reside in a directory that is listed in the ModulePath  option  of  FVWM  for  it  to  be
       executed by FVWM.

CONFIGURATION OPTIONS

       The follow option is the only only support at present

       *FvwmWinListDesk DeskNumber command
              Specifies the command to execute when the specified DeskNumber becomes active.

              If  the  command begins with -solid FvwmBacker uses the next argument as a color in the X database
              and sets the background to that color without generating a system call to  xsetroot.  Only  single
              word color names may be used.

SAMPLE CONFIGURATION

       The following are excepts from a .fvwmrc file which describe FvwmBacker initialization commands:

       ####
       # Set Up Backgrounds for different desktops.
       ####
       *FvwmBackerDesk 0 -solid steelblue
       *FvwmBackerDesk 1 -solid midnightblue
       *FvwmBackerDesk 2 -solid yellow
       *FvwmBackerDesk 3 xpmroot /usr/include/X11/pixmaps/background2.xpm
