Ubuntu Manpage: icewm - lightweight X11 window manager

NAME

        icewm - lightweight X11 window manager

SYNOPSIS

       icewm [OPTIONS]

DESCRIPTION

icewm is a window manager for the X11 window system. It aims to be small, fast and familiar to new
users.

icewm is called a re-parenting window manager, because it draws small frames around application windows.
By dragging this frame with the mouse, windows are resized or moved.

Because windows may overlap, icewm is also a stacking window manager. Many windows may exist, some
hidden behind others.

icewm supports a configurable number of virtual desktops. These are called workspaces. Related windows
are grouped on a dedicated workspace. By switching between workspaces, the user can attend to different
tasks, while keeping oversight. This is supported by a task bar and a pager.

The installation comes with several themes. Choose a theme via a menu.

icewm is compliant with the ICCCM and EWMH window manager specifications.

PROGRAMS
The icewm package includes several programs:

icewm(1)
The actual window manager. It positions application windows on screen and decorates them with
borders. It gives input focus to the current active application. icewm supports different focus
modes, which are explained below. It draws a small task bar at the bottom of the screen, which gives
easy access to programs, to virtual desktops, to active applications, and to a small set of
monitoring applets.

icewmbg(1)
The background setting application. It can assign plain background color or images in different
formats to the X background. Each workspace can have its own background. It supports semi-
transparency. Semitransparent background image and colour can be configured. When the background
image has changed then icewmbg(1) can be notified to update the background. Multi-head monitor
setups are fully supported. See the icewmbg(1).

icewm-session(1)
icewm-session(1) is the preferred program to start the IceWM system. It first loads additional
environment variables from the optional env file. Then it starts icewmbg(1) and icewm. It also runs
the startup script and implements basic session management. On termination the shutdown script will
be run first, then icewm-session(1) will terminate icewm and icewmbg(1). icewm-session(1) will also
start the optional icesound(1) if you give it the --sound option. See icewm-session(1).

icesh(1)
A powerful tool to control window properties and to interact with the window manager. It is typically
used in shell scripts. See icesh(1).

icehelp(1)
A small document browser, which is used by icewm to display the 'IceWM manual' and some man pages.

icewmhint(1)
A utility for passing IceWM-specific window options to icewm. The options are used to configure the
first application which is started subsequently. See icewmhint(1).

icesound(1)
Plays audio files on GUI events which are raised by icewm. It supports ALSA, AO and OSS. See the
icesound(1) man page.

icewm-menu-fdo(1)
Generate an icewm menu with executable desktop applications according to XDG specifications. See the
icewm-menu-fdo(1) man page.

icewm-set-gnomewm(1)
Configures GNOME to start IceWM instead of its own WM.

OPTIONS

COMMON OPTIONS
Each of the IceWM executables supports the following options:

-c, --config=FILE
Use FILE as the source of configuration options. By default icewm looks for a file named
preferences. This is a readable text file which can be modified with the help of a text editor.

-t, --theme=NAME
Use NAME as the name of the icewm theme to use. A theme defines the look and feel of icewm, like
colors, fonts and buttons.

--display=DISPLAY
DISPLAY specifies the connection to the X11 server. By default the environment variable "DISPLAY" is
used.

--sync
This option specifies to use a slower synchronous communication mode with the X11 server. This is
irrelevant for normal use.

-h, --help
Gives a complete list of all the available command-line options with some very brief explanation.

-V, --version
Shows the software release version for this program.

ICEWM OPTIONS
The icewm program supports some additional options:

-a, --alpha
Use a 32-bit visual for translucency. This can also be set in the preferences file as "Alpha=1".

--replace
Instructs icewm to replace an existing window manager. Provided that the window manager being
replaced is ICCCM 2.0 compliant, once it notices that it is to be replaced it will cease operations
and typically stop execution. This allows icewm to establish itself as the only active window
manager.

-r, --restart
Tell icewm to restart itself. This reloads the configuration from file.

-s, --splash=IMAGE
Briefly show IMAGE on startup in the center of the screen. This can also be set in the preferences
file as Splash="image.jpg".

--configured
Shows a list of configuration options which were enabled when icewm was compiled from source code.
This can be helpful if one suspects some functionality may be missing.

--directories
Gives a list of directories where icewm will look for configuration data. This list is printed in
the actual order in which icewm uses it to search for configuration files.

-l, --list-themes
icewm will search all the configuration directories for theme files and print a list of all found
themes.

-p, --postpreferences
This gives a long list of all the internal icewm options with their actual values after icewm has
processed all of the configuration and theme files. In some advanced scenarios this can be helpful to
inspect which configuration was chosen or whether option formatting was correct.

--rewrite-preferences
Overwrite an existing preferences file with an icewm default preferences, but preserve all
modifications insofar they deviate from the defaults.

--extensions
Give a list of the current X extensions, their versions and status.

--trace=conf,font,icon,prog,systray
Enable tracing of the paths which are used to load configuration, fonts, icons, executed programs,
and/or system tray applets.

USAGE

TASKBAR
On startup icewm launches the task bar at the bottom of the screen. The task bar consists from left to
right of the following components:

The Menu button in the lower left corner gives access to the icewm root menu. This menu has sub-menus to
start applications, to control icewm settings, and the icewm Logout menu.

The Show Desktop button unmaps all application windows to fully uncover the desktop.

The Window List Menu button gives access to a menu with a list of active windows for the current
workspace and a list of workspaces with sub-menus for their active application windows.

The Toolbar is a list of icons for applications which are defined in the toolbar configuration file.

The Workspace Pane shows one button for each workspace. The current workspace is indicated by a pressed
button. Clicking another workspace switches to that workspace. Press left mouse, then the Shift key,
then release the left mouse, takes the current window to that workspace. Press left, then Alt, then
release left, moves only the focused window to other workspace, without changing the current workspace.

The workspaces are defined in the preferences file. To change a name for only this session, double
click, edit the name and hit Enter. When "PagerShowPreview" is turned on, a small graphical window
summary for each workspace is shown. They support drag-and-drop: dragging a Firefox tab to a workspace
button changes the current workspace. Then releasing it moves that tab to a new window in that
workspace.

The Task Pane consists of a list of wide buttons for each application which is running on the current
workspace, or all workspaces if "TaskBarShowAllWindows=1". Each task button shows the application icon
and the application title. The active application is indicated by a pressed button. This is the
application which has input focus. Pressing another button activates that application: it is brought to
the foreground and receives input focus. Other mouse controlled activities on the window buttons are:
dragging window buttons with the left mouse button to rearrange the order, closing the application window
with "Alt" + middle button, lowering the application window with "Ctrl" + middle button, or bringing the
application window to the current workspace with "Shift" + middle button if "TaskBarShowAllWindows=1".

If there are not many application buttons then a stretch of plain task bar is visible. Clicking on it
with the right mouse button gives the task bar menu. Even with a full task pane, this menu can be
usually accessed by right-clicking the bottom right corner of the taskbar.

The Tray Applet shows system tray objects.

The APM Applet shows battery power status.

The Net Applet shows network activity. Network devices to monitor are given by the "NetworkStatusDevice"
option.

The Memory Applet monitors memory usage.

The CPU Applet monitors processor utilization.

The Mailbox Applet monitors mailbox status changes. See the section MAILBOX MONITORING below.

The Clock Applet shows the current time and date. It is configured by the "TimeFormat" option.

The Task Bar Collapse button collapses the task bar and hides it.

Not all icewm applets may show up on the task bar. They must have been enabled during configuration of
the icewm software. Their appearance is also controlled by options in the preferences file.

INPUT FOCUS
Of all visible windows only one can be the active window. This is the window which has input focus. It
is the primary receiver of keyboard and mouse events and hence one can interact with the application
which created that window. A primary task of a window manager is to allow the user to switch input focus
between different windows. The primary means to do this is the mouse pointer. By moving the mouse
pointer over the screen to another window, and perhaps also by clicking on a window, input focus can be
directed.

The "FocusMode" option controls the way icewm gives input focus to applications. It is initialized by
the focus_mode configuration file. The focus mode is set via the Focus menu. icewm supports six focus
models:

1. Click-to-focus
The default focus mode. In this mode changing input focus requires to click a window with the left
mouse button. The window is raised if needed. When an application requests focus its task pane
button flashes. This gives the option to honor this request or to ignore it. When a new application
window appears it automatically receives focus. Also when a hidden application raises to the front
it receives focus.

2. Sloppy-mouse-focus
Sets input focus merely by moving the mouse pointer over a window. It is called sloppy, because if
the mouse then leaves the window and moves to the desktop background the input focus remains with the
last active window. When a window receives focus it is raised. When an application requests focus
its task pane button flashes. A new application or an application which raises to the front
automatically receives focus.

3. Explicit-focus
Focus is even more user-controlled than Click-to-focus. When a window receives focus it is not
raised by default, unless the frame border is clicked. No flashing occurs when an application
requests focus. When a new application window appears it does not receive focus. Only by explicit
clicking on a window is focus directed.

4. Strict-mouse-focus
Like Sloppy but focus remains with the last window. New applications don't receive focus and are
mapped behind other windows. When an application raises to the front it still does not get focus.

5. Quiet-sloppy-focus
Like Sloppy but no disturbing flashing occurs on the task bar when an application requests focus.

6. Custom-mode
A focus mode which is defined in detail by ten options in the preferences file. These are:
"ClickToFocus", "FocusOnAppRaise", "RequestFocusOnAppRaise", "RaiseOnFocus", "RaiseOnClickClient",
"FocusChangesWorkspace", "FocusOnMap", "FocusOnMapTransient", "FocusOnMapTransientActive",
"MapInactiveOnTop".

All non-Custom focus modes override these ten options.

Apart from the mouse, icewm supports changing input focus in two ways by keyboard. By pressing "Alt+Esc"
or "Alt+Shift+Esc", input focus is immediately changed to the next or previous window, which will be
raised to make it fully visible. The other method involves the quick switch.

QUICK SWITCH
The QuickSwitch is a means to quickly and interactively change the input focus to another window. It is
activated by pressing the "Alt+Tab" or "Alt+Shift+Tab" key combination. A window pops up in the centre
of the screen with a list of windows to choose from. A narrow band indicates a selection: the candidate
window that will be activated to receive input focus when the Alt key is released.

The selection can be changed. By repeatedly pressing the Tab key, one can cycle over all windows. If a
Shift key is down, the direction of traversal is reversed. Or use the scroll wheel of the mouse. Or use
one of the digit keys to select the corresponding window from the list. Arrow keys are also supported,
as well as the Home and End key.

To make a selected window the active window, just release the Alt key, or hit the Return key, or click on
it. To cancel the QuickSwitch, press Escape or click outside of the QuickSwitch window.

A selected window can be closed by Delete, "Alt+F4", or the middle mouse button. While the QuickSwitch
window is up, one can still change workspace with the usual workspace hotkeys.

The QuickSwitch has two distinct modes: vertical and horizontal. The window list can include all windows
or be limited to the current workspace. See the many preferences available for the QuickSwitch.

WINDOW PLACEMENT
A second important task of a window manager is to place new windows on the screen. By default icewm
chooses a placement with minimal overlap, but this is determined by the "SmartPlacement" option in the
preferences file. If "SmartPlacement" is turned off then windows are placed in sequence from left to
right and top to bottom. One can also turn on "ManualPlacement". Then new windows appear initially in
the top left corner and the mouse cursor changes into a fist. By moving the fist cursor to a suitable
location and clicking the new window will appear at the mouse click location.

WINDOW LAYERS
Windows can overlap. Which window appears on top is determined by three features. Newer windows appear
over older windows. By clicking on a window it is raised to the top. But both are overruled by the
window layer. Windows can be placed in different layers via the Layers menu. Click with the right mouse
button on the window frame and select Layer. From there choose one of seven window layers. These are
ordered from higher to lower. Windows in higher layers appear over windows in lower layers.

WORKSPACES
icewm supports multiple virtual desktops called workspaces. A workspace is like a screen where a subset
of all application windows are mapped. Thanks to multiple workspaces we can more easily manage a large
number of applications. The number of workspaces and their names are configurable in the preferences
file through the "WorkspaceNames" option. By default four workspaces are created with the names 1, 2, 3
and 4 thus:

WorkspaceNames=" 1 ", " 2 ", " 3 ", " 4 "

This syntax is typical for icewm options which receive multiple values. It is a list of comma-separated
values each of which can be quoted.

The workspaces are visible on the toolbar. One can switch to a different workspace by pressing the
workspace button in the toolbar, but after becoming familiar with the 'keyboard shortcuts' below one will
want to use a hotkey to choose a workspace. If the "EdgeSwitch" options is enabled in the preferences
file (with sub-options "HorizontalEdgeSwitch" and "VerticalEdgeSwitch") then one can move to the next or
previous workspace by moving the mouse to the edge of the screen. The "ContinuousEdgeSwitch" option
enables continuous movement to subsequent workspaces. The "EdgeSwitchDelay" option says how long to wait
before a change of workspace occurs.

To move an application window to a different workspace one can use a keyboard shortcut. Another option
is to select the Move To submenu in the window menu of the window frame.

DRAG AND DROP
The task bar supports drag and drop operations. When a drag is in progress, the destination window can be
activated by hovering the drag icon over the task button for that window. Alternatively, the current
workspace can be changed by hovering the drag icon over the desired workspace button. When edge
switching is enabled, the current workspace can also be changed by bringing the drag icon to the screen
edge.

ADDRESS BAR
If EnableAddressBar=1 then KeySysAddressBar="Alt+Ctrl+Space" activates the address bar in the task bar.
If ShowAddressBar=1 it is always shown. This is a command-line in the task bar where a shell command can
be typed. Pressing "Enter" will execute the command. AddressBarCommand="/bin/sh" will be used to
execute the command. On "Control+Enter" the command is executed in a terminal as given by
TerminalCommand. The address bar maintains a history which is navigable by the Up and Down keys. It
supports command completion using "Tab" or "Ctrl+I". A rich set of editing operations is supported,
including cut-/copy-/paste-operations.

WINDOW LIST
The window list window shows a list of all workspaces. For each workspace it shows the window titles of
the windows which are mapped on it. The bottom entry reads "All Workspaces". It holds the sticky windows.
These windows are mapped in all workspaces.

The window list window is normally hidden. Choose one of the following four methods to make it visible:

• Select the bottom window list menu entry.

• Press the "KeySysWindowList=Ctrl+Alt+Esc" key.

• Press the right Windows key if "Win95Keys=1"

• Press the "DesktopWinListButton=2" mouse button in the root window.

• Press the middle mouse button in a workspace button on the task bar.

A single-click on a window entry selects it. A group of windows can be selected by
"Shift+Pointer_Button1" or by dragging with the left mouse button. Use "Ctrl+Pointer_Button1" to
individually select windows in a multi-selection. A right mouse click over a selection will popup the
system menu for this selection. To close the selected windows, press "Delete". Press "Shift+Delete" to
forcefully kill them. Right mouse click below the sticky windows for a menu with window arranging
actions.

Double-click on a workspace to switch to it. Double-click on a window to activate it. Or navigate by
arrow keys and press Enter. The space bar toggles a selection of a window. "Ctrl+a" and "Ctrl+/" will
select the entire list of windows. "Ctrl+\\" deselects everything. Press the first letter of a window
title to navigate to it and select it. If titles of multiple windows start with the same letter then
repeatedly pressing the first letter cycles over those windows. "Home" selects the first entry and "End"
the last. "PageUp" and "PageDown" move up or down by ten entries. Combine this with the "Shift" key to
extend a selection over the range of motion.

MAILBOX MONITORING
The task bar can show one or more icons to reflect the status of a mailbox. The mailbox can be a local
file or a remote POP or IMAP account. For this a couple of options must be set. First,
TaskBarShowMailboxStatus must be enabled, which it is by default. Then the location of the mailbox must
be set. Icewm first looks for MailBoxPath in preferences. If this is unset, it looks at the environment
variables "MAILPATH" and "MAIL". MailBoxPath may contain a space-separated list of mailboxes, while
"MAILPATH" may contain a colon-separated list of mailboxes. If a mailbox starts with a slash "/", then
it is a local file, otherwise a URL. These are six examples of possible mailboxes:

file:///var/spool/mail/captnmark
file:///home/captnmark/Maildir/
pop3://markus:%2f%40%3a@maol.ch/
pop3s://markus:password@pop.gmail.com/
imap://mathias@localhost/INBOX.Maillisten.icewm-user
imaps://mathias:password@imap.gmail.com/INBOX

The POP3S and IMAPS schemes use "openssl" for TLS/SSL encryption. Note that for IceWM to access Gmail
you must first configure your Gmail account to enable POP3 or IMAP access. Make sure you have secure
file permissions on your IceWM preferences file and the directory which contains it.

Reserved characters in the password, like slash, at and colon can be specified using escape sequences
with a hexadecimal encoding like %2f for the slash or %40 for the at sign. For example, to hex-encode
"!p@a%s&s~" use this Perl snippet:

perl -e 'foreach(split("", $ARGV[0])) { printf "%%%02x", ord($_); };
print "\n";' '!p@a%s&s~'

Which will print:

%21%40%23%24%25%5e%26%2a%7e

This is the hex-encoded password. However, it is unwise to store a password in your preferences. Consider
a wallet extension for IceWM.

IceWM will check a mailbox periodically. The period in seconds can be set by the MailCheckDelay option,
which is 30 seconds by default.

Whenever new mail arrives, the mailbox icon will be highlighted. The color will indicate if the mail has
been read or not. Hovering the mouse over the mailbox icon will show a tooltip with more details. A
command can be also be run on new mail. Set the NewMailCommand option. Its environment will have these
variables set by IceWM:

ICEWM_MAILBOX
The mailbox index number of MailBoxPath starting from 1.

ICEWM_COUNT
The total number of messages in this mailbox.

ICEWM_UNREAD
The number of unread messages in this mailbox.

KEYBOARD LAYOUT SWITCHING
To control keyboard layouts on the task bar, define in preferences the option KeyboardLayouts to a comma-
separated list of your preferred keyboard layouts. For example:

KeyboardLayouts="de","fr","jp"

A keyboard layout can simply be a name. Usually this is a two-letter country code. See the directory
/usr/share/X11/xkb/symbols for a list of available keyboard layouts for your system. If it is enclosed
in double quotes, it can also be a space-separated list of command-line arguments to an invocation of the
"setxkbmap" program.

The first layout is the default. It will be installed when icewm starts. The task bar will show the
current keyboard layout. If an icon can be found for the first two letters of the layout, then that icon
will be shown. Otherwise the first two letters of the name of the layout will be shown.

Click on the current keyboard layout to cycle through all the available keyboard layouts. Click with the
right mouse button to open a menu of all available keyboard layouts.

It is also possible to configure a default keyboard layout for each program individually in the
icewm-winoptions(5) file. Whenever such a program receives input focus, icewm will install this
configured keyboard layout automatically. The keyboard status on the task bar will be updated to reflect
this.

Please note that for keyboard layout switching to work, the "setxkbmap" program must be installed. To see
your current keyboard layout settings, do "setxkbmap -query".

KEYBOARD SHORTCUTS
icewm supports a large number of hotkeys to activate some behaviour with a single key combination. These
are all configurable in the preferences file. Here we give their preferences name, followed by their
default value in double quotes, and a short descriptions of their effect.

Note that all use one or more key modifiers. Icewm supports the following modifiers: Alt, AltGr, Ctrl,
Hyper, Meta, Shift, Super. Setting ModSuperIsCtrlAlt=1 makes the Super modifier an alias for Ctrl+Alt.

KeySysSwitchClass="Alt+grave"
Is like "KeySysSwitchNext" but only for windows with the same WM_CLASS property as the currently
focused window.

MOUSE BINDINGS
You can control windows by a modified mouse button press:

MouseWinMove="Alt+Pointer_Button1"
Moves the window under the mouse over the screen.

MouseWinSize="Alt+Pointer_Button3"
Resizes the window. Keep the key and button pressed. To enlarge the window move the mouse button
away from the center. To shrink it move towards the centre.

MouseWinRaise="Ctrl+Alt+Pointer_Button1"
Raises the window under the mouse.

MouseWinLower="Ctrl+Alt+Pointer_Button1"
Lowers the window under the mouse. If this is equal to "MouseWinRaise" and the window can be raised
then "MouseWinRaise" takes preference over "MouseWinLower".

The title frame of a window also listens for mouse clicks. Left double clicking maximizes the window
("TitleBarMaximizeButton=1"). Press Shift to only maximize vertically. Press Alt+Shift for horizontally.
Middle double clicking rolls up the window ("TitleBarRollupButton=2"). Also press Shift to maximize
horizontally. If TitleBarRollupButton is either 4 or 5 then the scroll wheel controls rolling up or down.
Pressing a mouse button and moving it will move the window. "Alt+Pointer_Button1" lowers the window.

When the mouse is on the window frame then a left click raises the window. Dragging with the left button
down resizes the window. Clicking the right button pops up the context menu. Dragging with the right
button moves the window.

Clicking on the desktop activates a menu. The middle button shows the window list
("DesktopWinListButton=2"). The right button shows the root menu ("DesktopMenuButton=3"). If you press
"Ctrl+Alt" then the mouse wheel will focus all applications in turn.

SIGNALS

       icewm supports the following signals:

       SIGHUP
           icewm will restart itself. It is a way to reload the configuration.

       SIGINT, SIGTERM
           icewm will cease to manage application windows and terminate.

       SIGQUIT
           icewm will initiate the logout procedure.  If a "LogoutCommand" preferences option was configured it
           will be executed.

       SIGUSR2
           Toggle the logging of X11 events, if "logevents" was configured.

ENVIRONMENT VARIABLES

       ICEWM_PRIVCFG
           The directory for user private configuration files.  When this environment variable is not specified,
           the default directory is $XDG_CONFIG_HOME/icewm when that directory exists, otherwise the default
           value is $HOME/.icewm.

       DISPLAY
           The name of the X11 server.  See Xorg(1) or Xserver(1).  This value can be overridden by the
           --display option.

       MAILPATH, MAIL
           Gives the location of your mailbox.  If the schema is omitted the local "file" schema is assumed.
           This is used by the mailbox applet in the task bar to show the status of your mailbox.  If the
           "MailBoxPath" option in the preferences file is set, then that one takes precedence.

FILES

CONFIGURATION DIRECTORIES
icewm looks for configuration files in the following directories, in the given order, until it finds one:

$ICEWM_PRIVCFG/
Contains user-specific configurations. When ICEWM_PRIVCFG is specified, this directory takes
precedence over $XDG_CONFIG_HOME/icewm and $HOME/.icewm.

$XDG_CONFIG_HOME/icewm/
Contains user-specific configurations. When this directory exists it take precedence over
$HOME/.icewm.

$HOME/.icewm/
Contains user-specific configurations. This is the historical default directory.

/etc/X11/icewm/
Contains system-wide customized defaults. Please note that your local installation may have been
configured to use a different system location. The output of "icewm --directories" will show this
location.

/usr/share/icewm/
Default local installation settings.

CONFIGURATION FILES
env icewm-session(1) loads additional environment variables from the file env. Each line is subjected to
POSIX shell expansion by wordexp(3). Comment lines starting by a hash-sign ("#") are ignored.
icewm-session(1) will load those expanded lines which contain a name, followed by an equals sign,
followed by the value (which may be empty).

See icewm-env(5).

focus_mode
Defines the initial value for "FocusMode". Its default value is "FocusMode=1" (Click-to-focus).
This can be changed via the menu. icewm will save the Focus menu choice in this file.

See icewm-focus_mode(5).

keys
Global keybindings to launch applications, which need not be window manager related. Each non-empty
line starts with the word "key". After one or more spaces follows a double-quoted string of the
bound X11 key combination like "Alt+Ctrl+Shift+X". Then after at least one space follows a shell
command-line which will be executed by icewm whenever this key combination is pressed. For example,
the following line creates a hotkey to reload the icewm configuration:

key "Ctrl+Shift+r" icesh restart

See icewm-keys(5).

menu
A menu of applications; usually customized by the user. icewm provides the icewm-menu-fdo(1) program
to generate a default menu. Similar programs are xdg_menu(1), mmaker(1) (MenuMaker), xde-menu(1),
xdgmenumaker(1).

See icewm-menu(5).

preferences
Contains general settings like paths, colors and fonts, but also options to control the icewm focus
behaviour and the applets which are started in the task bar. The icewm installation will provide a
default preferences file, which can be copied to the icewm user configuration directory and modified.

See icewm-preferences(5).

prefoverride
Settings which override the settings from a theme. Some of the icewm configuration options from the
preferences file which control the look-and-feel may be overridden by the theme, if the theme
designer thinks this is desirable. However, this prefoverride file will again override this for a
few specific options of your choosing. It is safe to leave this file empty initially.

See icewm-prefoverride(5).

programs
An automatically generated menu of applications. This could be used by wmconfig(1), menu or similar
programs to give easy access to all the desktop applications which are installed on the system.

See icewm-programs(5).

theme
This file contains the name of the default theme. On startup icewm reads this file to obtain the
theme name, unless icewm was started with the --theme option. Whenever a different theme is selected
from the icewm Menu then the theme file is overwritten with the name of the selected theme. This
theme file contains the keyword "Theme", followed by an equals sign, followed by a double-quoted
string with the theme name. The theme name is the name of the theme directory, followed by a slash,
followed by the theme file. Usually the theme file is just default.theme, but a theme may have
alternatives. Alternatives are small tweaks of a theme. These are specified in their own .theme
file, which replaces default.theme. If no theme file exists then icewm will use the default setting
of "Theme="default/default.theme"".

See icewm-theme(5).

toolbar
Contains names of quick to launch applications with icons for the task bar. Each non-empty non-
comment line starts with the keyword prog. After one or more spaces follows a name, which is
displayed in a tool tip whenever the mouse cursor hovers over the toolbar icon. This name may be a
double quoted string. Then follows the bare name of the icon to use without extensions. This icon
will be shown in the toolbar. The last component is a shell command-line which will be executed
whenever the user presses the icon in the toolbar. For example, the following line in toolbar will
create a button with tool tip "Mozilla Firefox" with the firefox icon which launches firefox(1) when
clicked:

prog "Mozilla Firefox" firefox /usr/bin/firefox --private-window

See icewm-toolbar(5).

winoptions
Contains settings to control window appearance and behaviour which are specific to applications or
groups of applications. Options can control the border, whether it appears on the task bar, the
window list, the system tray and the workspaces. Also its layer, geometry, whether it can be moved,
resized and closed.

See icewm-winoptions(5).

startup
Contains commands to be executed on icewm startup. This is an executable script with commands to
tweak X11 settings and launch some applications which need to be active whenever icewm is started.
It is run by icewm-session(1) when icewm starts.

See icewm-startup(5).

shutdown
Contains commands to be executed on icewm shutdown. This is an executable script with commands to be
executed in the last stage of icewm termination. Typically they may undo some of the effects of the
startup script. It is run by icewm-session(1) when icewm terminates.

See icewm-shutdown(5).

CONFIGURATION SUBDIRECTORIES
icons
Contains icons which are used to identify applications. Usually these files are in the XPM format,
but the PNG and SVG image formats are also supported. The names of icon files may follow a specific
naming pattern, like app_32x32.xpm. They start with a base name, usually this is just a single word.
Then follows an underscore, followed by a size specification in the format "SIZExSIZE". This is
followed by a dot and the file extension, where the extension denotes the icon image format. Common
sizes are 16, 32 and 48 for small, large and huge icons. This depends on the respective "IconSize"
preferences options.

ledclock
Pictures of digits for the LED clock which is displayed in the bottom-right corner of the task bar.
These can be seen when the "TaskBarShowClock" and "TaskBarClockLeds" options are both set to 1.

mailbox
Icons which are used to display different states of the mailbox applet in the task bar. There are
five states and each has its own icon: mail.xpm, newmail.xpm, unreadmail.xpm, nomail.xpm,
errmail.xpm.

sounds
Audio files which are played by icesound(1) on GUI events. These are: startup.wav, shutdown.wav,
restart.wav, launchApp.wav, workspaceChange.wav, windowOpen.wav, windowClose.wav, dialogOpen.wav,
dialogClose.wav, windowMax.wav, windowRestore.wav, windowMin.wav, windowHide.wav, windowRollup.wav,
windowMoved.wav, windowSized.wav, windowLower.wav.

taskbar
Pictures to customize the look of the task bar. These include: taskbarbg.xpm, taskbuttonactive.xpm,
taskbuttonbg.xpm, taskbuttonminimized.xpm, toolbuttonbg.xpm, workspacebuttonactive.xpm,
workspacebuttonbg.xpm.

themes
A directory to store themes. Each theme is stored in its own sub-directory in the themes directory.
A theme contains at least a default.theme file, and optionally theme alternatives which are
additional files which have a .theme file name extension and which contain tweaks of the
default.theme file. How to create a theme is explained in the IceWM Theme Creation Howto.

OPACITY
IceWM supports window opacity and transparency in connection with an external compositor like compton(1)
or picom(1). If a client window sets the "_NET_WM_WINDOW_OPACITY" property on its window, then icewm
will copy this to the outer frame window, where the compositor will read it and adjust the opacity
accordingly.

The opacity can also be set in the icewm-winoptions(5) file. icesh(1) can control the opacity level of
running applications.

The _NET_WM_WINDOW_TYPE properties which icewm sets on its windows are DIALOG, NOTIFICATION, POPUP_MENU
and TOOLTIP. The output of "icesh windows" shows their WM_CLASS values. These can be helpful to configure
compton.

EXAMPLES

       Examples of the above configuration files can be found in the default installation path or in the system-
       wide defaults.  See the output of "icewm --directories" for their locations.
