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 man-
ager 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. (her-
itage 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 win-
dow 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 fvwm2(1), section MODULE COMMANDS), and looks for certain configu-
ration 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 win-
dowID of the window that the event refers to, new_desk will have
the new desk number. The windowID is a hexadecimal string pre-
ceded 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: 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
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.
Provided fvwm supports it (not yet), there's an additional event
to replace all fvwm beeps with a sound:
*FvwmEvent: beep beep.au
The toggle_paging event will be supported, as soon, as it's res-
urrected by fvwm:
*FvwmEvent: toggle_paging fwop.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 use-
ful 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 orig-
inal work by Robert Nation.
