NAME
     FvwmEvent - the FVWM Event module

SYNOPSIS
     FvwmEvent is a more versatile replacement for FvwmAudio.  It
     can in general be used to hook any fvwm2 function or program
     to any window manager event. e.g: Delete unwanted  netscape-
     popups  or  application  error  popups  as they appear, play
     sounds, log events to a file  and  the  like.  Be  creative,
     You'll find a use for it.

     FvwmEvent is spawned by fvwm2(1), so no command line invoca-
     tion will work.  From within the .fvwm2rc file, FvwmEvent is
     spawned as follows:

     Module FvwmEvent

     or from within an fvwm2 pop-up menu:

     DestroyMenu Module-Popup
     AddToMenu Module-Popup "Modules"      Title
     +                      "Event"        Module FvwmEvent
     +                      "Auto"         Module FvwmAuto 200
     +                      "Buttons"      Module FvwmButtons
     +                      "Ident"        Module FvwmIdent
     +                      "Banner"       Module FvwmBanner
     +                      "Pager"        Module FvwmPager 0 3


DESCRIPTION
     The FvwmEvent module  communicates  with  the  fvwm2  window
     manager to bind actions to window manager events.  Different
     actions may be assigned to distinct window manager events.

     FvwmEvent can be used to bind sound  files  to  events  like
     FvwmAudio (RiP) did. It can be used for logging event traces
     to a log file, while debugging fvwm2.

     FvwmEvent can  also  have  builtin  support  for  the  rplay
     library.  (heritage of FvwmAudio)


CONFIGURATION OPTIONS
     FvwmEvent reads the same .fvwm2rc file as fvwm2  reads  when
     it starts up, and looks for certain configuration options:


     *FvwmEventCmd command
          This determines the fvwm2 function that is to be called
          with the event parameters.  You might want to do one of
          the following (details below):

               *FvwmEventCmd builtin-rplay
                              play sounds
               *FvwmEventCmd
                              execute distinct fvwm2 functions
               *FvwmEventCmd exec
                              execute distinct external programs

          This version of FvwmEvent  has  builtin  rplay  support
          which  does not need to invoke an external audio player
          to play sounds.  The  rplay  support  is  enabled  when
          FvwmEvent  is compiled with HAVE_RPLAY defined (see the
          Imakefile) and when FvwmEventCmd  is  set  to  builtin-
          rplay.

          For example:

               *FvwmEventCmd builtin-rplay
               *FvwmEvent add_window drip.au

          rplay can be obtained via anonymous ftp at
               <URL:ftp://ftp.sdsu.edu/pub/rplay>
          or   <URL:ftp://ftp.x.org/contrib/Event/rplay>

          FvwmEvent also has support for any other external  pro-
          gram.  e.g: the rsynth 'say' command:

               *FvwmEventCmd /rsynth/say
               *FvwmEvent destroy_window "window closed"

          You can  also  use  fvwm2's  builtin  Echo  command  as
          FvwmEventCmd  to  obtain  debug output for fvwm2 events
          quietly.  I used this setup to debug FvwmAuto:

               *FvwmEventCmd Echo
               *FvwmEvent focus_change "focus change"
               *FvwmEvent raise_window "raise window"

          You can even call different  shell  commands  for  each
          event just by setting

               *FvwmEventCmd exec
               *FvwmEvent add_window killname "APPL ERROR"


     *FvwmEvent window-manager-event action-or-filename
          Binds particular actions to window manager events.

          e.g. for audio-events:

               *FvwmEvent startup TaDa.au
               *FvwmEvent shutdown Elvis_Left.au
               *FvwmEvent unknown doh.au
               *FvwmEvent new_page beam_trek.au
               *FvwmEvent new_desk beam_trek.au
               *FvwmEvent add_window drip.au
               *FvwmEvent raise_window swoosh.au
               *FvwmEvent lower_window swoosh.au
               *FvwmEvent configure_window hammer.au
               *FvwmEvent focus_change boing.au
               *FvwmEvent destroy_window explosion.au
               *FvwmEvent iconify ploop.au
               *FvwmEvent deiconify ploop.au
               *FvwmEvent window_name huh.au
               *FvwmEvent icon_name beep.au
               *FvwmEvent res_class beep.au
               *FvwmEvent res_name beep.au
               *FvwmEvent end_windowlist twang.au

               *FvwmEvent icon_location beep.au
               *FvwmEvent map beep.au
               *FvwmEvent error beep.au
               *FvwmEvent config_info beep.au
               *FvwmEvent end_config_info beep.au
               *FvwmEvent icon_file beep.au
               *FvwmEvent default_icon beep.au
               *FvwmEvent string plapper.au

               *FvwmEvent mini_icon beep.au
               *FvwmEvent windowshade beep.au
               *FvwmEvent dewindowshade beep.au

          Provided fvwm2 supports it (not yet), there's an  addi-
          tional event to replace all fvwm2 beeps with a sound:

               *FvwmEvent beep beep.au

          The toggle_paging event will be supported, as soon,  as
          it's resurrected by fvwm2:

               *FvwmEvent toggle_paging fwop.au


     *FvwmEventDelay 5
          Specifies that an event-action will only be executed if
          it  occurs at least 5 seconds after the previous event.
          Events that occur during the delay period are  ignored.
          This  option is useful if you don't want several sounds
          playing at the same time.  The default delay is 0 which
          disables the Event delay.



RPLAY OPTIONS
     The following options are  only  valid  with  builtin  rplay
     support.   i.e:  when FvwmEvent was compiled with HAVE_RPLAY
     defined  (see  the  Imakefile).  They  are  used   only   if
     FvwmEventCmd is set to builtin-rplay.



     *FvwmEventRplayHost hostname
          Specifies what host the rplay sounds will play on.  The
          hostname  can  also  be an environment variable such as
          $HOSTDISPLAY.


     *FvwmEventRplayPriority 0
          Specifies what priority will be assigned to  the  rplay
          sounds when they are played.


     *FvwmEventRplayVolume 127
          Specifies what volume will be assigned  to  the  sounds
          when they are played.


INVOCATION
     The invocation method was shown in the synopsis section.  No
     command  line  invocation  is  possible.  FvwmEvent  must be
     invoked by the fvwm2 window manager.



FvwmAudio Compatibility
     FvwmAudioPlayCmd  used  to   call   an   external   program.
     FvwmEventCmd  calls an fvwm2 function. External programs can
     be called using the fvwm2 exec function "exec program".

     FvwmAudioDir has been removed  due  to  the  fact  that  the
     parameters don't have to be files any more.  use:

          DestroyFunc mysay
          AddToFunc mysay "I" exec /rsynth/say /rsynth/audiofiles/$1

          *FvwmEventCmd mysay


BUGS
     It's REALLY noisy when fvwm2 starts and  restarts  using  an
     audio player.  FvwmEventDelay helps a little bit.

     The parameters inherent to several events are  not  accessi-
     ble.  This  might  be  implemented in the future so that the
     command  executed   by   fvwm2   looks   like   FvwmEventCmd
     FvwmEvent-parameters event-specific-parameters.

     Simple FvwmAuto could then be emulated by:
          *FvwmEventCmd
          *FvwmEvent raise-window Raise


COPYRIGHTS
     This module has evolved  of  FvwmAudio,  which  in  term  is
     heavily  based  on a similar Fvwm module called FvwmSound by
     Mark Boyns. FvwmAudio simply took  Mark's  original  program
     and  extended  it to make it generic enough to work with any
     Audio player. Due  to  different  requests  to  do  specific
     things  on  specific  events,  FvwmEvent  took this one step
     further and now calls any fvwm2 function, or  builtin-rplay.
     If  fvwm2's  Exec function is used, any external program can
     be called with any parameter.

     The concept  for  interfacing  this  module  to  the  Window
     Manager, is original work by Robert Nation.
