FvwmEvent(1)                     Fvwm Modules                     FvwmEvent(1)



NAME
       FvwmEvent - the fvwm event module

SYNOPSIS
       FvwmEvent is a more versatile replacement for FvwmAudio.  It can in
       general be used to hook any fvwm function or program to any window
       manager event. E.g: Delete unwanted Netscape Pop ups or application
       error pop ups 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 fvwm, so no command line invocation will work.
       From within the .fvwm2rc file, FvwmEvent is spawned as follows:

       Module FvwmEvent

       or from within an fvwm pop-up menu:

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


DESCRIPTION
       The FvwmEvent module communicates with the fvwm 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 fvwm.

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


INVOCATION
       The invocation method was shown in the synopsis section. No command
       line invocation is possible. FvwmEvent must be invoked by the fvwm
       window manager. FvwmEvent accepts a single argument:


       -audio Enables FvwmAudio compatibility mode.


       alias  Makes FvwmEvent use alias as its name. This affects which lines
              from the user's configuration file are used.

              Invoking FvwmEvent as FvwmAudio (either by using an alias or
              creating a symlink) enables FvwmAudio compatibility mode.




CONFIGURATION OPTIONS
       FvwmEvent gets config info from fvwm's module configuration database
       (see fvwm(1), section MODULE COMMANDS), and looks for certain
       configuration options:


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

                   # play sounds
                   *FvwmEvent: Cmd builtin-rplay

                   # execute distinct fvwm functions
                   *FvwmEvent: Cmd

                   # execute distinct external programs
                   *FvwmEvent: Cmd exec

              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 and when FvwmEvent: Cmd is set to builtin-
              rplay. See remarks below if FvwmEvent is invoked in FvwmAudio
              compatibility mode.

              For example:

                   *FvwmEvent: Cmd 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/audio/rplay>

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

                   *FvwmEvent: Cmd "Exec /rsynth/say"
                   *FvwmEvent: destroy_window "window closed"

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

                   *FvwmEvent: Cmd Echo
                   *FvwmEvent: focus_change "focus change"
                   *FvwmEvent: raise_window "raise window"

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

                   *FvwmEvent: Cmd exec
                   *FvwmEvent: add_window 'killname "APPL ERROR"'


       *FvwmEvent: PassId
              Specifies that the event action will have an ID parameter added
              to the end of the command line. Most events will have the
              windowID of the window that the event refers to, new_desk will
              have the new desk number. The windowID is a hexadecimal string
              preceded by 0x, desk numbers are decimal.


       *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: old_add_window drip.au
                   *FvwmEvent: raise_window swoosh.au
                   *FvwmEvent: lower_window swoosh.au
                   *FvwmEvent: old_configure_window hammer.au
                   *FvwmEvent: focus_change boing.au
                   *FvwmEvent: enter_window boing.au
                   *FvwmEvent: leave_window 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: visible_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

                   *FvwmEvent: visible_name beep.au
                   *FvwmEvent: sendconfig beep.au
                   *FvwmEvent: restack beep.au
                   *FvwmEvent: add_window beep.au
                   *FvwmEvent: configure_window beep.au

                   *FvwmEvent: visible_icon_name beep.au
                   *FvwmEvent: enter_window beep.au
                   *FvwmEvent: leave_window beep.au
                   *FvwmEvent: property_change beep.au

              The window related event handlers are executed within a window
              context.  Previously PassId was used for this purpose, but now
              using PassId is not needed.

              Note: The enter_window event is generated when the pointer
              enters a window.  With the -passid option, that window's id is
              passed to fvwm.  An enter_window event is generated too when the
              pointer leaves a window and moves into the root window.  In this
              case, the id passed is 0.

              Note: When the shutdown event arrives, FvwmEvent may be killed
              before it can trigger the associated action.

              Provided fvwm supports it (not yet), there's an additional event
              to replace all fvwm beeps with a sound:

                   *FvwmEvent: beep beep.au


       *FvwmEvent: Delay 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.


       *FvwmEvent: StartDelay delay
              Specifies that an event-action will only be executed if it
              occurs at least delay seconds after the startup event. Events
              that occur during the delay period are ignored.  This option is
              useful when fvwm starts and restarts using an audio player.  The
              default delay is 0.


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



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


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


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


FvwmAudio Compatibility Mode
       When invoked in FvwmAudio compatibility mode (see above), FvwmEvent
       accepts the following options to provide backwards compatibility for
       FvwmAudio:


       *FvwmEvent: PlayCmd command
              This is equivalent to using *FvwmEvent: Cmd to Exec commands.
              This determines the independent audio player program that will
              actually play the sounds. If the play command is set to builtin-
              rplay then the builtin rplay support will be used.


       *FvwmAudio: Dir directory
              Specifies the directory to look for the audio files.  This
              option is ignored when rplay is used.


BUGS
       It's REALLY noisy when fvwm starts and restarts using an audio player.
       You can use FvwmEvent: StartDelay to fix this problem.


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 fvwm function, or builtin-rplay. If fvwm'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.
