# IceWM Manual

Marko Macek
version 2.2.1, 2021 March 17

## Introduction

This document is the manual for the IceWM X11 window manager. The IceWM manpages provide additional documentation.

The goal of IceWM is to provide a small, fast and familiar window manager for the X11 window system, which is compatible with the EWMH and ICCCM window manager protocols. Generally, it tries to make all functions available both by keyboard and by mouse (this is not currently possible when using mouse focus).

IceWM originally was designed to emulate the look of Motif, OS/2 Warp 4, OS/2 Warp 3 and Windows 95. Since it has a theming engine others styles are possible. A large number of original themes have been created and published by users.

Further information can be found at the IceWM website, at the current site of development, which includes the support requests.

## Copying

IceWM and its documentation are covered by a GNU LGPL license, which is included in the distribution.

## First steps

### IceWM components

The IceWM suite consists of the following core applications provided by the main package:

- icewm - The actual window manager binary. It handles window placement and draws the window decorations.

- icewmbg - The background setting application. It can assign plain background color or images in different formats to the X background. Either shared or separate for different workspaces. This program should be started before `icewm`.

- icewm-session - The IceWM session manager runs all of the above. This is the preferred program to start IceWM.

- icewm-menu-fdo - This generates IceWM program menus from FreeDesktop `.desktop` files.

- icewmhint - Is a simple utility for passing IceWM hints to IceWM by window class and instance. Icewmhint uses a special property, '"_ICEWM_WINOPHINT"', on the root window to pass special hints to IceWM.

- icehelp - Is used by icewm to display the 'IceWM manual' and the manpages. See the output of `icehelp --help` for details.

- icesh - Could be used to manage IceWM internals from the command line.

### Starting icewm

The `icewm` program alone is suitable for use with desktop environments like GNOME. If you wish to run the whole IceWM suite (WM, background changer, Docklet support, and startup/shutdown script handling), use the `icewm-session` binary instead of pure `icewm`. Note that this is not a complete Session Manager but it helps to automate the startup.

First make sure that you choose the correct X startup script in your home directory. For most distributions either the file `$HOME/.xsession` or `$HOME/.xinitrc` is honored by startx and X display managers like KDM. On RedHat, the `$HOME/.Xclients` may be used instead. In all cases, choose the one recommended by your distribution and make sure that there is no concurrency between the X startup scripts. Ensure that the script is executable. Mine looks something like this:

    #!/bin/bash
    # run profile to set $PATH and other env vars correctly
    . $HOME/.bash_profile
    # setup touchpad and the external mouse
    xset m 7 2
    xinput set-ptr-feedback 0 7 1.9 1

    # start icewm-session
    exec icewm-session
    xterm

The xterm on the last line is there simply to make sure that your X session doesn’t crash if IceWM does (should never happen). You can restart IceWM from there or start some other window manager. The session will close if you close the xterm.

### Startup and shutdown scripts

After initialization `icewm-session` will search the resource path for a `startup` script. If this file is found and if it is executable `icewm-session` will run this script. During termination of `icewm-session` the `shutdown` script is executed.

Example `~/.icewm/startup` script:

    #!/bin/bash

    [ -x ~/.icewm/restart ] && source ~/.icewm/restart

    gnome-terminal --geometry 80x25+217+235 &
    xscreensaver &

On termination the `shutdown` script will be run first, then `icewm-session` will terminate icewm and icewmbg.

Tip | `icewm-session` is meant for easy desktop initialization and it is part of IceWM due to popular demand. For more sophisticated session management one could use a real session manager. IceWM supports the XSESSION protocol.

### Extra session environment

Please note that if icewm-session is used as the only startup mechanism (without having .xsession involved), one can write additional environment settings into the file `$HOME/.icewm/env`. Expansion of simple shell style variables should be supported on most platforms. Shell command expansion is supported if `wordexp` was configured. This extra environment is only effective in applications started by icewm-session and their subprocesses.

Example `env`:

    PATH=~/bin:$PATH
    LANG=de_DE.UTF-8

## Focus models

IceWM implements four general focus models:

- clickToRaise

  Exactly like Win95, OS/2 Warp. When window is clicked with a mouse, it is raised and activated.

- clickToFocus

  Window is raised and focused when titlebar or frame border is clicked. Window is focused but not raised when window interior is clicked.

- pointerFocus

  When the mouse is moved, focus is set to window under a mouse. It should be possible to change focus with the keyboard when mouse is not moved.

- explicitFocus

  When a window is clicked, it is activated, but not raised. New windows do not automatically get the focus unless they are transient windows for the active window.

Detailed configuration is possible using the configuration file options.

## Mouse Commands

### Frame Commands

- Left Button

  Select and raise the window. On the window frame, resize the window.

- Right Button

  When dragged, moves the window. When clicked, displays the context menu.

### Title Bar Commands

- Any Button Drag

  Move the window.

- Alt + Left Button

  Lower the window.

- Left Button Double Click

  Maximize/Restore the window.

- Middle Button Double Click

  Rollup/Unroll the window.

The Ctrl key can be used together with a mouse button to prevent a window from being raised to the top of the stack.

### Taskbar commands

- Left Button Click

  Activate the workspace with the window and raise the window. Toggles the minimized/active state of the window.

- Shift + Left Button Click

  Move window to current workspace. This only works when windows from all workspaces are shown on the taskbar all the time.

- Control + Left Button Click

If AddressBarCommand was configured it will be used to execute the command otherwise `/bin/sh` is used. If the Control key was also pressed then 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. A rich set of editing operations is supported, including cut-/copy-/paste-operations and file completion using Tab or Ctrl-I.

- `Ctrl+Alt+d`

  Show the desktop.

- `Ctrl+Alt+h`

## The Resource Path

IceWM looks in several locations for configuration information, themes and customization; together these locations are called the resource path. The resource path contains the following directories:

$ICEWM_PRIVCFG; $XDG_CONFIG_HOME/icewm; $HOME/.icewm The first of these which is defined and existent is used to search for the user’s personal customization.

/etc/icewm the system-wide defaults directory

/usr/share/icewm OR /usr/local/share/icewm the compiled-in default directory with default files

The directories are searched in the above order, so any file located in the system/install directory can be overridden by the user by creating the same directory hierarchy under `$HOME/.icewm`.

To customize icewm yourself, you could create the `$HOME/.icewm` directory and copy the files that you wish to modify, like `preferences`, `keys` or `winoptions`, from `/etc/icewm`, `/usr/share/icewm` or `/usr/local/share/icewm` and then modify as you like.

To customize the default themes, create the `$HOME/.icewm/themes` directory and copy all the theme files there and then modify as necessary. Each theme has its own subdirectory. Themes can be downloaded from https://themes.ice-wm.org.

## Configuration Files

IceWM uses the following configuration files:

- theme

  Currently selected theme

- preferences

  General settings - paths, colors, fonts…​

- prefoverride

  Settings that should override the themes.

- keys

  Global keybindings to launch applications (not window manager related)

- toolbar

  Quick launch application icons on the taskbar.

## Theme

The `theme` file contains the currently selected theme. It will be overwritten automatically when a theme is selected from the Themes menu.

### Mailbox Monitoring (updated 2018-03-04)

- `MailCheckDelay = 30`

  Delay between new-mail checks. (seconds).

- `MailBoxPath = ""`

This may contain a list of mailbox specifications. Mailboxes are separated by a space. If `TaskBarShowMailboxStatus` is enabled then IceWM will monitor each mailbox for status changes each `MailCheckDelay` seconds. For each mailbox IceWM will show an icon on the taskbar. The icon shows if there is mail, if there is unread mail, or if there is new mail. Hovering the mouse pointer over an icon shows the number of messages in this mailbox and also the number of unread mails. A mailbox can be the path to a file in conventional mbox format. If the path points to a directory then Maildir format is assumed. Remote mail boxes are specified by an URL using the Common Internet Scheme Syntax (RFC 1738):

    scheme://user:password@server[:port][/path]

Supported schemes are `pop3`, `pop3s`, `imap`, `imaps` and `file`. The `pop3s` and `imaps` schemes depend on the presence of the `openssl` command for `TLS/SSL` encryption. This is also the case if `port` is either `993` for imap or `995` for pop3. When the scheme is omitted then `file` is assumed. IMAP subfolders can be given by the path component. Reserved characters 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:

    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

To help solve network protocol errors for pop3 and imap set the environment variable `ICEWM_MAILCHECK_TRACE`. IceWM will then log communication details for POP3 and IMAP mailboxes. Just set `export ICEWM_MAILCHECK_TRACE=1` before executing icewm, or set this in the `env` configuration file.

Note that for IceWM to access Gmail you must first configure your Gmail account to enable POP3 or IMAP access. To allow non-Gmail applications like IceWM to use it see the Gmail help site for "Let less secure apps use your account". Also set secure file permissions on your IceWM preferences file and the directory which contains it. It is unwise to store a password on file ever. Consider a wallet extension for IceWM. The following Perl snippet demonstrates how to hex encode a password like `!p@a%s&s~`:

    perl -e 'foreach(split("", $ARGV[0])) { printf "%%%02x", ord($_);  }; print "\n";' '!p@a%s&s~'
    %21%40%23%24%25%5e%26%2a%7e

## Menus and Toolbar (updated 2018-05-06)

### menu

Within the `menu` configuration file you can configure which programs are to appear in the root/start menu.

Submenus can be created with:

    menu "title" icon_name {
    # contained items
    }
    separator
    menufile "title" icon_name filename
    menuprog "title" icon_name program arguments
    menuprogreload "title" icon_name timeout program arguments
    include filename
    includeprog program arguments

Menus can be populated with submenus and with program entries as explained below for the `program` configuration file. Comments start with a #-sign.

The `menufile` directive creates a submenu with a title and an icon, while `menuprog` and `menuprogreload` create a submenu with entries from the output of `program arguments` where the timeout of `menuprogreload` says to reload the submenu after the timeout expires. The `include` statement loads more configuration from the given filename, while `includeprog` runs `program arguments` to parse the output.

### toolbar

The `toolbar` configuration file is used to put programs as buttons on the taskbar. It uses the same syntax as the `menu` file.

### programs

Usually automatically generated menu configuration file of installed programs. The `programs` file should be automatically generated by `wmconfig` (Redhat), `menu` (Debian), or `icewm-menu-fdo`.

Programs can be added using the following syntax:

    prog "title" icon_name program_executable options

Restarting another window manager can be done using the restart program:

    restart "title" icon_name program_executable options

icon_name can be `-` if icon is not wanted, or `!` if the icon name shall be guessed by checking the command (i.e. the real executable file, following symlinks as needed).

The "runonce" keyword allows to launch an application only when no window has the WM_CLASS hint specified. Otherwise the first window having this class hint is mapped and raised. Syntax:

    runonce "title" icon_name "res_name.res_class" program_executable
    options
    runonce "title" icon_name "res_name" program_executable options
    runonce "title" icon_name ".res_class" program_executable options

The class hint of an application window can be figured out by running

    xprop WM_CLASS

Submenus can be added using the same keywords as the `menu` configuration file.

Only double quotes are interpreted by IceWM. IceWM doesn’t run the shell automatically, so you may have to do that.

## Hot Keys

IceWM allows launching of arbitrary programs with any key combination. This is configured in the `keys` file. The syntax of this file is like:

key "key combination" program options…​

For example:

    key  "Alt+Ctrl+t"  xterm -rv
    key "Ctrl+Shift+r" icewm --restart
    runonce "Alt+F12"  "res_name.res_class" program_executable options

## Window Options (updated 2018-03-04)

The winoptions file is used to configure settings for individual application windows. Each line in this file must have one of the following formats:

- window_name.window_class.option: argument

- window_name.window_role.option: argument

- window_class.option: argument

- window_name.option: argument

- window_role.option: argument

- .option: argument

The last format sets a default option value for all windows. Each window on the desktop should have name and class resources associated with it. Some applications also have a window role resource. They can be determined using the `xprop` utility. When used on a toplevel window, `xprop | grep -e CLASS -e ROLE` should output a line like this:

    WM_CLASS = "name", "Class"

and may also display a line like this:

    WM_WINDOW_ROLE = "window role"

It’s possible that an application’s name and/or class contains a dot character (.), which is also used by IceWM to separate name, class and role values. In this case precede the dot with the backslash character. In the following example, we suppose an application’s window has `the.name` as its name value and `The.Class` as its class value and for this combination we set option to argument.

    the\.name.The\.Class.option: argument

Options that can be set per window are as follows:

- icon

  The name of the icon.

- workspace

  Default workspace for window (number, counting from 0)

- layer

  The default stacking layer for the window. Layer can be one of the following seven strings:

  - Desktop Desktop window. There should be only one window in this layer.

  - Below Below default layer.

  - Normal Default layer for the windows.

  - OnTop Above the default.

  - Dock Layer for windows docked to the edge of the screen.

  - AboveDock Layer for the windows above the dock.

  - Menu Layer for the windows above the dock.

## Icon handling

### Generic

The window manager expects to find two XPM files for each icon specified in the configuration files as ICON. They should be named like this:

- ICON_16x16.xpm

  A small 16x16 pixmap.

- ICON_32x32.xpm

  A normal 32x32 pixmap.

- ICON_48x48.xpm

  A large 48x48 pixmap.

Other pixmap sizes like 20x20, 24x24, 40x40, 48x48, 64x64 might be used in the future. Perhaps we need a file format that can contain more than one image (with different sizes and color depths) like Windows'95 and OS/2 .ICO files.

It would be nice to have a feature from OS/2 that varies the icon size with screen resolution (16x16 and 32x32 icons are quite small on 4000x4000 screens ;-)

### GDK-Pixbuf

When icewm was configured with the `--enable-gdk-pixbuf` option all of GdkPixbuf’s image formats are supported. Use them by specifying the full filename or an absolute path:

- ICON.bmp

  A PPM icon in your IconPath.

- /usr/share/pixmap/ICON.png

  An PNG image with absolute location.

## Mouse cursors

IceWM scans the theme and configuration directories for a subdirectory called cursors containing monochrome but transparent XPM files. To change the mouse cursor you have to use this filenames:

- left.xbm

  Default cursor (usually pointer to the left).

- right.xbm

  Menu cursor (usually pointer to the right).

- move.xbm

  Window movement cursor.

- sizeTL.xbm

  Cursor when you resize the window by top left.

- sizeT.xbm

  Cursor when you resize the window by top.

- sizeTR.xbm

  Cursor when you resize the window by top right.

- sizeL.xbm

  Cursor when you resize the window by left.

- sizeR.xbm

  Cursor when you resize the window by right.

- sizeBL.xbm

  Cursor when you resize the window by bottom left.

- sizeB.xbm

  Cursor when you resize the window by bottom.

- sizeBR.xbm

  Cursor when you resize the window by bottom right.

## Themes

Themes are used to configure the way the window manager looks. Things like fonts, colors, border sizes, button pixmaps can be configured. Put together they form a theme.

Theme files are searched in the `themes` subdirectories.

These directories contain other directories that contain related theme files and their .xpm files. Each theme file specifies fonts, colors, border sizes, …​

The theme to use is specified in `~/.icewm/theme` file:

- `Theme = "nice/default.theme"`

  Name of the theme to use. Both the directory and theme file name must be specified.

If the theme directory contains a file named fonts.dir created by mkfontdir the theme directory is inserted into the X servers font search path.

www.box-look.org has a very large number of themes which were created by users of IceWM.

## Command Line Options

`icewm` supports the following options:

    -d, --display=NAME
    NAME of the X server to use.

    --client-id=ID
    Client id to use when contacting session manager.

    --sync
    Synchronize X11 commands.

    -c, --config=FILE
    Load preferences from FILE.

    -t, --theme=FILE
    Load theme from FILE.

    --postpreferences
    Print preferences after all processing.

    -V, --version
    Prints version information and exits.

    -h, --help
    Prints this usage screen and exits.

    --replace
    Replace an existing window manager.

    -r, --restart
    Tell the running icewm to restart itself.

    --configured
    Print the compile time configuration.

    --directories
    Print the configuration directories.

    -l, --list-themes
    Print a list of all available themes.

The restart option can be used to reload the IceWM configuration after modifications. It is the preferred way to restart IceWM from the command line or in scripts. To load a different theme from the command line, combine this with the `--theme=NAME` option like:

    icewm -r -t CrystalBlue

The theme name will then be saved to the 'theme' configuration file, before restarting IceWM.
