Thanks to Thomas Adam and Tavis Ormandy for the pointers about the
PackWindow complex functions (in reply to my SnapWindow patch
<
http://www.hpc.uh.edu/fvwm/archive/0502/msg00024.html>). I'm scanning
through the fvwm2rc as we speak. But speaking of complex functions...
Fvwm has SloppyFocus styles, FPGrabFocus, and all sorts of related funky
focus options. But I needed something a little more sophisticated. So,
without further ado:
################################################################################
# Automatic window focusing, raising and warping
Style * ClickToFocus, MouseFocusClickRaise
# Do a minimal-distance warp to inside the window's border -- distance
# inside (in pixels) can be specified as single parameter, defaults to
# 10.
DestroyFunc Warp_If_Outside
AddToFunc Warp_If_Outside
+ I PipeRead " \
x=$[pointer.wx]; y=$[pointer.wy]; border=$0; \
[[ ! "${border}" ]] && border=10; \
[[ ${x} -lt ${border} ]] && x=${border}; \
[[ ${y} -lt ${border} ]] && y=${border}; \
[[ ${x} -gt $(($[w.width]-${border})) ]] && x=$(($[w.width]-${border})); \
[[ ${y} -gt $(($[w.height]-${border})) ]] && y=$(($[w.height]-${border}));\
echo WarpToWindow ${x}p ${y}p;"
DestroyFunc AutoRaise_Raise_Func
AddToFunc AutoRaise_Raise_Func
+ I Raise
+ I FlipFocus
+ I Warp_If_Outside
DestroyFunc AutoRaise_Add
AddToFunc AutoRaise_Add
+ I WindowId $* (CurrentDesk AcceptsFocus !Iconic) AutoRaise_Raise_Func
DestroyFunc AutoRaise_Destroy
AddToFunc AutoRaise_Destroy
+ I DeSchedule $*
+ I Prev (CurrentDesk AcceptsFocus !Iconic) AutoRaise_Raise_Func
DestroyFunc AutoRaise_Enter
AddToFunc AutoRaise_Enter
+ I WindowId $* Silent FlipFocus
+ I Schedule 750 $* WindowId $* Silent Raise
DestroyFunc AutoRaise_Leave
AddToFunc AutoRaise_Leave
+ I DeSchedule $*
*AutoRaise:PassId
*AutoRaise:add_window AutoRaise_Add
*AutoRaise:destroy_window AutoRaise_Destroy
*AutoRaise:enter_window AutoRaise_Enter
*AutoRaise:leave_window AutoRaise_Leave
Module FvwmEvent AutoRaise
################################################################################
So, what have we achieved? Without using SloppyFocus or any other
strange focusing options, fvwm is now configured to
a) Emulate SloppyFocus (without actually using it)
b) Emulate FvwmAuto (Autoraise windows after 750 miliseconds)
c) Emulate FPGrabFocus and FPReleaseFocus
d) Warp the mouse pointer to inside a newly created window, or back
to the previously focused window on window destruction (I
couldn't find any simple way to do this, leading to this
solution).
Is it possible to emulate ALL fvwm's *Focus options (and a couple of
other Style settings) using FvwmEvent like this? If so, is it really a
good idea keeping these styles, since we're effectively duplicating
functionality? If the styles are removed, will fvwm be noticably
smaller and more memory-efficient? Shouldn't such a blatantly useful
module be integrated directly into fvwm, possibly through
automatically-called functions (i.e. FvwmAddWindow, FvwmEnterWindow,
analogous to InitFunction and its ilk)?
Oh, and most important, does anybody else have pointers to other cool
complex configuration ideas using FvwmEvent, Schedule, PipeRead and the
other less-commonly used options?
Cheers!
