NAME
FvwmIconMan - an Fvwm Icon Manager
SYNOPSIS
FvwmIconMan is spawned by fvwm, so no command line invoca-
tion will work.
DESCRIPTION
FvwmIconMan is an icon manager modeled after the TWM icon
manager. The user may have multiple icon managers, each of
which armed with a list of window types which it manages.
For example, the user may have one manager which lists only
emacs windows, and another which lists everything else. You
may also specify what resolution each icon manager uses, for
example, one icon manager may manage windows on all desks,
and another may manage only those on the current desk, or
page. If you have applied the MiniIcons patch to fvwm2, then
FvwmIconMan can display the miniature icons for its managed
windows. The managers may have a maximum number of columns
(and so grows vertically), a maximum number of rows (and
then grows horizontally), or stay at a fixed size, and
adjust the size of the window buttons to fit (think win95's
Taskbar). And when support is compiled in for the X Shape
extension, then the manager windows may be shaped.
You can specify actions to be run when mouse, or key events
are received. For example, you could bind the first mouse
button to iconify the selected window, and make bindings for
the arrow keys to navigate the manager window without the
mouse.
FvwmIconMan can be set to display which window currently has
the keyboard focus, and by binding the select event (see
below) to the fvwm Focus function, you can emulate the TWM
icon manager's behavior.
INITIALIZATION
During initialization, FvwmIconMan searches though the fvwm
configuration file for the options which are described
below. It is highly recommended that you make FvwmIconMan be
a sticky window. And if you want to make use of the fol-
lowfocus option, and/or binding an action to Focus, then you
should make FvwmIconMan clicktofocus. Also, when using the
Shape option, it's recommended that the FvwmIconMan window
not be decorated at all by fvwm.
INVOCATION
FvwmIconMan can be invoked by inserting the line 'Module
FvwmIconMan' in the .fvwmrc file. If FvwmIconMan is to be
spawned during fvwm's initialization, then this line should
be placed in the InitFunction and ResetFunction declara-
tions, or it can be bound to a menu, mouse button, or keys-
troke to invoke it later. FvwmIconMan should be placed in
the ModulePath (defined in the .fvwmrc file) in order for
fvwm to find it.
If you wish to run FvwmIconMan in a transient mode, such as
with the built in window list, then pass Transient as an
argument. The invocation "Module FvwmIconMan Transient" will
do nicely. In this mode, FvwmIconMan will pop up one manager
window directly under the cursor. When the mouse button is
released, it will execute the appropriate action, and then
exit. Things are somewhat complicated by the fact that you
can specify that FvwmIconMan create multiple manager win-
dows, behavior which is unsuitable when running transiently.
So, when running transiently, FvwmIconMan will only create
one manager window. Use the manager id 'transient' to
specify options for this manager window.
CONFIGURATION OPTIONS REFERENCE CHART
FvwmIconMan has acquired quite a few options. I assume oth-
ers share my dislike of paging though a long manpage, so
here is a terse reference chart describing the available
options. They are described in more detail in the next sec-
tion.

CONFIGURATION OPTIONS
With the exception of the nummanagers option, all of the
options may be defined on a per-manager basis. So, for exam-
ple, the user may have his emacs manager with a red fore-
ground, and his xterm manager with a blue one. A configura-
tion line may therefore have one of two forms:
*FvwmIconMan*optionname optionvalue
To specify that the optionname takes the value option-
value for all managers.
*FvwmIconMan*managerid*optionname optionvalue
To specify that the option optionname takes the value
optionvalue for manager managerid. Mangerid may either
be a positive integer, or the string "transient". An
integral id refers to managers which FvwmIconMan
creates when running normally, and an id of "transient"
refers to the single manager which FvwmIconMan creates
when running transiently.
The following options may be specified:
*FvwmIconMan*nummanagers num
num is a positive integer specifying the total number
of icon managers. Since FvwmIconMan would like to know
how many managers there are before handling any manager
specific options, this should come first. The default
is 1.
*FvwmIconMan*[id*]action type binding
Binds an FvwmIconMan command to an event. Type may be
one of the values: Key, Mouse, or Select. Actions are
described in the following section ACTIONS.
*FvwmIconMan*[id*]background background
Specifies the default background color.
*FvwmIconMan*[id*]buttongeometry geometry
Specifies the initial geometry of an individual button
in pixels. If the specified height is 0, then the but-
ton height is determined from the font size. X and Y
coordinates are ignored.
*FvwmIconMan*[id*]drawicons value
If your version of fvwm2 is capable of using MiniIcons,
then this option determines if FvwmIconMan displays the
MiniIcons. Otherwise, it generates an error message.
"true" means that MiniIcons are shown for iconified
windows, "false" that MiniIcons are never shown, and
"always" that MiniIcons are shown for all windows.
*FvwmIconMan*[id*]focusbutton style [forecolor backcolor]
Same as the plainbutton option, but specifies the look
of buttons whose windows have the keyboard focus.
backcolor]
*FvwmIconMan*[id*]focusandselectbutton style [forecolor
Same as the plainbutton option, but specifies the look
of buttons which are both selected, and have the key-
board focus.
*FvwmIconMan*[id*]font font
Specifies the font to be used for labeling the buttons.
The default is 8x13.
*FvwmIconMan*[id*]foreground foreground
Specifies the default foreground color.
*FvwmIconMan*[id*]format formatstring
A printf like format string which describes the string
to be printed in the manager window for each managed
window. Possible flags are: %t, %i, %c, and %r for the
window's title, icon, class, or resource name, respec-
tively. The default is "%c: %i". Warning: m4 reserves
the word format, so if you use m4, take appropriate
action.
*FvwmIconMan*[id*]iconname iconstring
Specifies the window icon name for that manager window.
Iconstring may either be a single word, or a string
enclosed in quotes. The default is "FvwmIconMan".
*FvwmIconMan*[id*]managergeometry geometry
Specifies the initial geometry of the manager, in units
of buttons. If height is 0, then the manager will use
width columns, and will grow vertically once it has
more than width windows. Likewise, if width is 0, it
will use height rows, and grow horizontally. If both
are nonzero, then the manager window will be exactly
that size, and stay that way. As columns are created,
the buttons will narrow to accommodate. If the
geometry is specified with a negative y coordinate,
then the window manager will grow upwards. Otherwise,
it will grow downwards.
*FvwmIconMan*[id*]plainbutton style [forecolor backcolor]
Specifies how normal buttons look. style may be one of
flat, up, down, raisededge, or sunkedge, and describes
how the button is drawn. The color options are both
optional, and if not set, then the default colors are
used. If on a monochrome screen, then the style option
is ignored, but must still be set.
*FvwmIconMan*[id*]resolution resolution
Specifies when the manager will display an entry for a
certain window. resolution may take one of the follow-
ing values: global, desk, or page. If global, then all
windows of the appropriate type (see the show and
dontshow options below) will be shown. If desk, then
only those windows on the current desk will be down.
And if page, then only those windows on the current
page will be shown. The default is global.
*FvwmIconMan*[id*]selectbutton style [forecolor backcolor]
Same as the plainbutton option, but specifies the look
of buttons when the mouse is over them.
*FvwmIconMan*[id*]shape boolean
If True, then use make the window shaped. Probably only
useful if you have multiple columns or rows. If FvwmI-
conMan wasn't compiled to support the Shape extension,
this generates an error message. When using shaped win-
dows, it's recommended that a fvwm style is made for
FvwmIconMan that has no borders. Otherwise, fvwm will
get confused.
*FvwmIconMan*[id*]title titlestring
Specifies the window title string for that manager win-
dow. Titlestring may either be a single word, or a
string enclosed in quotes. The default is "FvwmIcon-
Man". This will be drawn in the titlebar of the manager
window, if any, and in the title button, which is the
button drawn when the manager is empty.
*FvwmIconMan*[id*]titlebutton style [forecolor backcolor]
Same as the plainbutton option, but specifies the look
of the title button (the button drawn when the manager
is empty). The manager's title is drawn in the title
button.
The two following options control which windows get handled
by which managers. A manager can get two lists, one of win-
dows to show, and one of windows to ignore. If only the show
list is given, then that manager will show only the windows
in the list. If only the dontshow list is given, then the
manager will show all windows except those in the list. If
both lists are given, then a window will be shown if it is
not in the dontshow list, and in the show list. And finally,
if neither list is given, then the manager will handle all
windows. Each list is made up of patterns of the form
type=pattern, where type is one of class, resource, title,
or icon, and pattern is an expression of the same format
used in the fvwm style command (minimalistic shell pattern
matching). Quotes around the pattern will be taken as part
of the expression. If a window could be handled by more than
one manager, then the manager with the lowest id gets it.
*FvwmIconMan*[id*]show pattern list
If a window matches one of the patterns in the list,
then it may be handled by this manager.
*FvwmIconMan*[id*]dontshow pattern list
If a window matches one of the patterns in the list,
then it may not be handled by this manager.
*FvwmIconMan*[id*]usewinlist boolean
If true, then honor the WinListSkip style flag. Other-
wise, all windows are subject to possible management
according to the show and dontshow lists.
*FvwmIconMan*[id*]followfocus boolean
If true, then the button appearance reflects which win-
dow currently has focus. Default is false.
*FvwmIconMan*[id*]sort value
If name, then the manager list is sorted by name. If
namewithcase, then it is sorted by name sensitive to
case. If id, then the manager list is sorted by the
window id, which never changes after the window is
created. Or it can be set to none, which results in no
sorting. Default is name.
ACTIONS
Actions are commands which may be bound to an event of the
type: a keypress, a mouse click, or the mouse entering a
window manager button - denoted by the action types Key,
Mouse, and Select.
Normally, actions bound to a mouse click are executed when
the button is pressed. In transient mode, the action is exe-
cuted when the button is released, since it is assumed that
FvwmIconMan was bound to some mouse event. A tip/warning:
FvwmIconMan still keeps track of the mouse button and any
modifier keys in this case, so if you bind FvwmIconMan to
say, meta-button3, then it would be wise to ensure that the
action you want to execute will be executed when the meta-
button3 event occurs (which would be the button release,
assuming you kept your finger on the meta key).
The syntax for actions are:
Key actions: Key Keysym Modifiers FunctionList
Keysym and Modifiers are exactly the same as for the
fvwm Key command.
Mouse actions: Mouse Button Modifiers FunctionList
Button and Modifiers are exactly the same as for the
fvwm Mouse command.
Select actions: Select FunctionList
A FunctionList is a sequence of commands separated by com-
mas. They are executed in left to right order, in one shared
context - which currently only contains a pointer to the
"current" button. If a button is selected (typically by the
mouse pointer sitting on it) when the action is executed,
then the current button is initialized to that button. Oth-
erwise, it points to nothing.
Most of the available commands then modify this "current"
button, either by moving it around, making it become the
selected button, or sending commands to fvwm acting on the
window represented by that button. Note that while this
current button is initialized to be the selected button, the
selected button does not implicitly follow it around. This
way, the user can send commands to various windows, without
changing which button is selected.
Commands take five types of arguments: Integer, Manager,
Window, Button, and String. A String is a string specified
exactly as for fvwm - either in quotes or as a single word
not in quotes. Again, you may bind a sequence of commands to
an event, by listing them separated by commas.
Window and Button types look exactly the same in the
.fvwm2rc file, but are interpreted as either specifying a
managed window, or a FvwmIconMan button representing a win-
dow. They can either be an integer (which is interpreted
module N where N is the number of buttons - so 0 is the
first and -1 is the last), or one of the strings: Select,
Focus, Up, Down, Right, Left, Next, Prev. Select and Focus
refer to the currently selected or focused button or window.
Up, Down, Right, and Left refer to the button or window
above, below, to the right of, or to the left of the current
button in the manager window, allowing navigation around the
manager window. Next and Prev designates the window, button,
or manager after or before the current button, allowing
navigation of the one dimensional list of windows which is
drawn in the manager window. If the manager is sorted, Next
and Prev move through the windows in the sorted order.
The Manager type can either be an integer, Next, or Prev.
The meaning is analogous to that of the Button type, but in
terms of the integral index of the managers, restricted to
managers which are nonempty.
The following functions are currently defined:
bif Button Integer/String
A relative branch instruction. If Button is Select or
Focus, then take the branch if there is a selected but-
ton or a focused button. If Button is an integer, then
branch if nonzero. If it is one of Up, Down, Right,
Left, Next, Prev, then the branch is taken when the
current button can move in that direction. If the
branch is taken, then Integer commands are skipped. No
backwards branches are allowed.
bifn Button Integer/String
The complement of bif. The branch is taken if Button
evaluates to false, by the criteria listed for bif.
gotobutton Button
Sets current button to Button. If Button is an integer,
then the current button is set to Button modulo the
number of buttons, in the whichever manager contains
the selected button, if any.
gotomanager Manager
Sets button to button 0 of Manager. This will only go
to a visible, nonempty manager. So an integral argument
is taken modulo the number of such managers.
jmp Integer/String
Executes a relative jump of Integer instructions. Back-
wards jumps are not allowed. The jump is computed rela-
tive to the instruction following the jmp.
label String
Provides a label that previous instructions can jump
to. It will not be visible to subsequent jump instruc-
tions, and the same label can be used multiple times in
the same instruction list (though it would be perverse
to do so.)
print String
Prints String to the console. Useful for debugging
actions.
quit Quits FvwmIconMan.
ret Stop executing the entire action.
select
Selects the current button, if any. If a select action
has been specified, it will then be run. Therefore, it
is considered unwise to set the select button in the
select action.
sendcommand Command
Sends the fvwm command Command to the window
represented by the current button, if any.
warp Warps cursor to current button, if any.
Examples:
gotobutton select, gotobutton Down, select
Selects the button below the currently selected button.
Since the current button is already initialized to the
selected button, this may be shortened to "gotobutton Down ,
select".
gotobutton Up, select
Selects the button above the currently selected button.
gotobutton 0, select
Selects the first button of the current manager. If there is
no current manager, which is the case when no button is
selected, then this does nothing.
gotobutton -1, select
Selects the last button of the current manager.
gotobutton focus, select
Selects the button corresponding to the focused window.
gotobutton focus, Iconify
Sends the fvwm command Iconify to the focused window. Note
that this does not change the selected button.
bif Next 3, gotobutton 0, select, ret, gotobutton Next, select
If a button is selected, and it's the last button, go to
button 0. If it's not the last button, go to the next but-
ton. Otherwise, do nothing. Basically, this action cycles
through all buttons in the current manager.
bif select 7, bif focus 3, gotomanager 0, select, ret, gotobutton focus, select, ret, gotobutton down, select
This is good for sending to FvwmIconMan with a SendToModule
command. If there is a selected button, it moves down. Oth-
erwise, if there is a focused button, it is selected. Other-
wise, button 0 of manager 0 gets selected.
bif select Select, bif focus Focus, gotomanager 0, select, ret, label Focus, gotobutton focus, select, ret, label Select, gotobutton down, select
Same as previous, but using the label instruction.
In addition to being bound to keys and mice, actions can be
sent from fvwm to FvwmIconMan via the SendToModule command.
Don't quote the command when using SendToModule. Also, due
to a bug in the current version of fvwm2, don't quote FvwmI-
conMan either.
SAMPLE CONFIGURATIONS
This first example is of a the simplest invocation of FvwmI-
conMan, which only has one manager, and handles all windows:
##############################################################
# Load any modules which should be started during
# fvwm initialization

# Make FvwmIconMan title-bar-less, sticky, and give it an icon
Style "Fvwm*" Icon toolbox.xpm,NoTitle,NoHandles,Sticky
Style "FvwmIconMan" HandleWidth 5, Handles, BorderWidth 5

This example is the Reader's Digest version of my personal
configuration. It has two managers, one for emacs and one
for everything else, minus things with no icon title. Only
windows on the current page are displayed. The use of the
drawicons and shape options requires that fvwm and FvwmIcon-
Man we compiled with the correct options. Note how the
geometry and show options are specified per manager, and the
others are common to all:

UNFINISHED BUSINESS
There is one bug that I know of. A honest to goodness solu-
tion to this would be appreciated. When an icon manager is
set to grow upwards or leftwards, on some machines it may
wander occasionally.
It doesn't handle windows without resource names as
gracefully as it should.
