FvwmAuto






FvwmAuto − the fvwm auto‐raise module


Module FvwmAuto Timeout [‐passid] [‐menter|‐menterleave|‐mfocus] [EnterCommand [LeaveCommand]]
FvwmAuto can only be invoked by fvwm.  Command line
invocation of the FvwmAuto will not work.


The FvwmAuto module is most often used to automatically
raise focused windows.


The correct syntax is:

     Module FvwmAuto Timeout [‐passid] [‐menter|‐menterleave|‐mfocus] [EnterCommand [LeaveCommand]]

     AddToMenu Modules
     + "Auto Raise (300 ms)"  Module FvwmAuto 300
     + "Auto Raise/Lower"     Module FvwmAuto 300 "Silent Raise" "Silent Lower"

The Timeout argument is required. It specifies how long a
window must retain the keyboard input focus before the
command is executed. The delay is measured in milliseconds,
and any integer greater than zero is valid.

If the literal option ‐passid is given, the window id of the
window just entered or left is appended to the command that
is sent to fvwm.  This can be used with the WindowId command
of fvwm.

The options ‐menter, ‐menterleave and ‐mfocus influence the
actions FvwmAuto reacts to.  No more than one of the options
can be chosen.  In ‐mfocus mode, FvwmAuto raises the window
that has the focus.  In ‐menter mode, FvwmAuto raises the
window under the pointer when the pointer enters a window.
The LeaveCommand is executed on the window that was below
the pointer before it entered the new window.  When the
pointer leaves a window and enters the root window, the
EnterCommand is executed too, but without a window to
operate on.  In ‐menterleave mode, FvwmAuto works just like
in ‐menter mode, but the LeaveCommand is also executed if
the pointer moves out of a window but does not enter a new
window.  The latter two modes of operation are useful with
windows that do not accept the focus.

Note: ‐menterleave mode can interfere with popup windows of
some applications.  One example is the zoom menu of
Ghostview.  Please do not complain about this to us ‐ it is
a bug in Ghostview.

EnterCommand and LeaveCommand are optional.  EnterCommand is
executed Timeout milliseconds after a window gets the input
focus, LeaveCommand is executed Timeout milliseconds after
the window has lost focus.  Note that you always should use









                             ‐2‐


the ’Silent’ keyword before the command itself.  FvwmAuto
prepends "Silent " to the command string on its own if yor
forget this.  Without this prefix fvwm would ask you for a
window to act on if the window has died before the command
sent by FvwmAuto has been processed by fvwm.  This can for
example happen with popup menus.

"Silent Raise" is the default for EnterCommand, but any fvwm
function is allowed. I would not use "Close" or "Destroy"
with a low timeout, though.  The LeaveCommand can be handy
for a tidy desktop.  Experiment with:

     Module FvwmAuto 0 Nop "Silent Lower"
     Module FvwmAuto 0 Nop "Silent Iconify"


An example for auto raising windows with ClickToFocus:

     Style * ClickToFocus
     FvwmAuto 0 ‐menter "Silent Raise"


An example for auto raising and lowering only some windows:
To start FvwmAuto:

     FvwmAuto 0 ‐passid ‐menter \
     "Silent selective_raiselower raise" \
     "Silent selective_raiselower lower"

And put this in your .fvwm2rc:

     AddToFunc selective_raiselower
     + I WindowId $1 (FvwmIconMan) $0
     + I WindowId $1 (FvwmButtons) $0
     + I WindowId $1 (xclock) $0
     ...


More complex example (three FvwmAuto’s are running):

     DestroyFunc RestoreIconified
     AddToFunc   RestoreIconified
     + I Current (Iconic) Iconify false

     DestroyFunc RegisterFocus
     AddToFunc   RegisterFocus
     + I Exec date +"%T $n focused" >>/tmp/focus‐stats.txt

     DestroyFunc RegisterUnfocus
     AddToFunc   RegisterUnfocus
     + I Exec date +"%T $n unfocused" >>/tmp/focus‐stats.txt

     KillModule FvwmAuto
     Module FvwmAuto 250 Raise Nop









                             ‐3‐


     Module FvwmAuto 800 RestoreIconified Nop
     Module FvwmAuto   0 RegisterFocus RegisterUnfocus





There is a special Raise/Lower support in FvwmAuto. It was
added to improve Raise/Lower callbacks, since most of
FvwmAuto usages is auto‐raising or auto‐lowering. This
improvement includes locking on M_RAISE_WINDOW and
M_LOWER_WINDOW packets and not raising/lowering explicitly
raised windows.  The special Raise/Lower support is enabled
only when either EnterCommand or LeaveCommand contain
substring "Raise" or "Lower". You can use this fact to
enable/disable any special support by renaming these
commands, if FvwmAuto does not automatically do want you
expect it to do.

Using FvwmAuto in conjunction with EdgeCommand can be even
more powerful. There is a short example in the fvwm man
page.



FvwmAuto just appeared one day, nobody knows how.
FvwmAuto was simply rewritten 09/96, nobody knows by whom.
