after-change-desk-hook (2 args)
- 
This hook is invoked just after the current desktop is changed.\n\
It is called with two argument, both integers.  The first is the\n\
new desktop number, the second is the old desktop number.  It\n\
is called after the desk is changed. See also `change-desk-hook'.
[From src/virtual.c:51]


after-new-window-hook (1 args)
- 
This hook is invoked after a window is created and placed.\n\
Its procedures are each called with a single argument, WIN, the new window.\n\
Any window operations may be performed at this time. However, it is\n\
recommended that placement-related operations, such as setting the\n\
position, desk, viewport location and z-ordering of a window be done\n\
in the placement procedure instead.  It should be used for setting\n\
window styles, as the window geometry needs to be fully and correctly\n\
specified before the window is placed.  The `window-style' mechanism\n\
from the "(app scwm style)" module provides a convenient interface to\n\
setting the relevant parameters when a new window is created. \n\
\n\
See also `before-new-window-hook' and `before-place-new-window-hook'.

after-viewport-position-change-hook (4 args)
- 
This hook is invoked just after the viewport position is changed.\n\
It is called with four arguments, all integers.  The first two are \n\
the x and y coordinates of the new viewport position in pixels and\n\
the second two are the change in x and y from the previous position.
[From src/virtual.c:63]


before-new-window-hook (1 args)
- 
This hook is invoked when first creating a new window object.\n\
Its procedures are each called with a single argument, WIN, the new\n\
window.  Only a subset of the usual window parameters should be set\n\
here, in particular, those that control what hints will be respected\n\
for this window, and those that control how the window will be placed.\n\
\n\
This hook does not typically need to be used directly by the user;\n\
`window-style' from the "(app scwm style)" module provides a convenient\n\
interface to setting the relevant parameters when a new window is\n\
created.\n\
\n\

[From src/add_window.c:106]


before-place-new-window-hook (1 args)
- 
This hook is invoked just before placing a new window.\n\
It comes after `before-new-window-hook', but before `after-new-window-hook'. \n\
Its procedures are each called with a single argument, WIN, the new window.\n\
This hook may be removed later since it is mostly redundant with the other\n\
two hooks, despite being invoked at a slightly different time. \n\
\n\

event.  The hook procedures are invoked with two arguments: the window object\n\
of the window that is now fully obscured, resulting-from-viewport-move? (a boolean).\n\
Beware that this event happens more often than you might expect and an action procedure\n\
attached here should be very careful about manipulating windows in a way\n\

invoked with one argument, WINID, the X id of the window that was destroyed. \n\

for a window scwm is managing. This indicates that an X window\n\
property has changed. Watching for window property changes can be used\n\
to construct your own custom window manager protocols. The hook\n\
procedures are invoked with two arguments, the name of the property\n\
that changed (as a string) and the window that it changed for. See also\n\
`X-root-PropertyNotify-hook' but beware it gets passed different\n\
arguments.
[From src/events.c:134]


X-root-PropertyNotify-hook (2 args)
- 
This hook is invoked whenever a PropertyNotify event is received\n\
on the root window.  This indicates that an X window\n\
property has changed. Watching for window property changes can be used\n\
to construct your own custom window manager protocols, or interface\n\
to other desktop environments such as KDE or GNOME. The hook\n\
procedures are invoked with two arguments: the atom for the changed\n\
property and a boolean telling whether the property was deleted. \n\
These arguments are different from those passed to\n\
