irxevent
SYNOPSIS
irxevent [config file]
DESCRIPTION
Irxevent is a program that I wrote to send button clicks
and key presses to X applications triggered by a LIRC
driven remote control. You can control your favorite
CD/MP3 player or your TV tuner program or any other X
application that responds to keyboard or mouse input. If
you like to you can send emacs ^X^S from your armchair.
Irxevent is a complement to irexec and irpty.

FILES
Irxevent works with the same config file as irexec and
irpty (~/.lircrc). For a complete sample .lircrc look at
examples/lircrc.
Part of your .lircrc could look like this:
begin
prog = irxevent
button = VIDEO_UP
config = Key SHIFT-KP_Add CurrentWindow
end
begin
prog = irxevent
button = VIDEO_DOWN
config = Key SHIFT-KP_Subtract CurrentWindow
end
begin
prog = irxevent
button = STOP
config = Key ctrl-c CurrentWindow
end
begin
prog = irxevent
button = 0
config = Key f xawtv
config = Key f xawtv
end
begin
prog = irxevent
button = POWER
config = Key q xawtv
end
end
Simply said config = lines may look like this:
config = Key [shift-][ctrl-][alt-]<key> <windowname> | WindowID id
| CurrentWindow | RootWindow
config = Button <button> <x> <y> <windowname> | CurrentWindow
config = xy_Key <x> <y> [shift-][ctrl-][alt-]<key> <windowname>
| WindowID id | CurrentWindow | RootWindow
some more examples:
config = Key Up xawtv
config = Key Down xawtv
config = Button 1 50 110 xclickme
config = Key q xawtv
config = Key ctrl-c mpg123
config = Key shift-Page_Up rxvt
In BNF this looks like:
LINE = "config =" <KEY|BUTTON|XYKEY> <TARGET>
XYKEY = "xy_Key" <x_position> <y_position> <MOD>Keyname
KEY = "Key" <MOD>Keyname
MOD = ["shift-"]["numlock-"]["ctrl-"]["alt-"]["meta-"]
["numlock-"]["mod3-"]["mod4-"]["scrlock-"]
BUTTON = "Button" <1..5> <x_position> <y_position>
TARGET = Windowname | "WindowID" id | "CurrentWindow" | "RootWindow"
Keyname:
is the key symbol that is declared in X windows. E.g.
"Up" refers to the cursor arrow pointing up. "KP_Add"
is the plus sign on the key pad. Just take a look at
irxevent.keys (in the documentation directory) if you
are not sure about a symbol's name.
Windowname:
can be the first characters of the window name dis
played by the window manager or the name that is dis
played below the icon. Some programs use the name
displayed by the window manager to show a lot of sta
tus information but don't change the icon name (like
xawtv). Others append information to the window name
("GQmpeg - kill_windooz.mp3"). If neither window name
nor icon name match the given Windowname information
from XClassHint(3x) will be checked.
CurrentWindow:
refers to the active window as returned by XGetInput
Focus(3x). Most times this is the window with your
mouse pointer in it.
RootWindow:
refers to the root window as returned by RootWin
dow(3x). You may need this to send events to the win
on your keypad).
There are programs that do not accept any synthetic X-
events by default because they can cause security prob
lems. Currently xterm and xemacs are known to ignore
events simulated by irxevent.
You can however make xterm accept external events by
enabling "Allow SendEvents" in the "Main Options" (hold
down the Ctrl button and press the left mouse button
inside the xterm window). You can as well place this line
into your .Xresources file to change this permanently:
XTerm.vt100.allowSendEvents: true
Yet another possibility is to start xterm like this:
xterm -xrm "XTerm.vt100.allowSendEvents: true"
xemacs will accept events if you set a built-in variable.
The following was taken from the online help:
`x-allow-sendevents' is a built-in boolean variable.
Value: t
Documentation:
*Non-nil means to allow synthetic events. Nil means
they are ignored.
Beware: allowing emacs to process SendEvents opens a
big security hole.
In order to allow events you have to evaluate this lisp
code (press Meta-x and enter the following expression):
(setq x-allow-sendevents t)
Placing this line into your .xemacs-options file should
have the same result.
If you have problems sending events please drop me an
email.
