FvwmBacker(1)

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. Actually, any arbitrary command can be sent to fvwm to execute, so you could also do things such as changing window border colors, etc.

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 following is the only supported option at present:

*FvwmBackerDesk 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). Otherwise the command is sent to fvwm to execute.

SAMPLE CONFIGURATION
The following are excepts from an .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 Exec xpmroot /usr/include/X11/pixmaps/background2.xpm
