NAME

blackbox - a window manager for X11

SYNOPSIS

blackbox -help | -version
blackbox [ -rc rcfile ] [ -display display ]

DESCRIPTION

Blackbox is a window manager for the Open Group's X Window System, Version 11 Release 6
and above. Its design is meant to be visually minimalist and fast.

Blackbox is similar to the NeXT interface and Windowmaker. Applications are launched using
a menu which is accessed by right clicking on the root window. Workspaces, a system of
virtual desktops are controlled via a menu which is accessed by middle clicking on the
root window and by using the toolbar. Individual windows can be controlled by buttons on
the title bar and more options are available by right clicking on the title bar.

Blackbox is able to generate beautiful window decorations on the fly at high speed.
Themes, called styles in Blackbox terminology, are very flexible but the use of pixmaps
has been purposefully avoided to eliminate dependencies and excess memory usage.

Blackbox itself does not directly handle key bindings like most other window managers.
This task is handled by a separate utility called bbkeys. Although Blackbox has a built-in
workspace (paging) system, bbpager, which provides a graphical pager, is popular with many
users. bbkeys, bbpager and several other bbtools can be found by going to
http://bbtools.thelinuxcommunity.org/
The slit is an edge of the screen which can hold specially designed programs called dock
apps (from Windowmaker). In addition, the popular program gkrellm will also run in the
slit. There is a huge selection of dockapps available and they run the gamut from must-
have gadgets to utterly useless (but cute and/or funny) eye candy.

OPTIONS

Blackbox supports the following command line options:

-help Display command line options, compiled-in features, and exit.

-version
Display version and exit.

-rc rcfile
Use an alternate resource file.

-display display
Start Blackbox on the specified display, and set the DISPLAY environment variable
to this value for programs started by Blackbox.

STARTING AND EXITING BLACKBOX

The most common method for starting Blackbox is to place the the command "blackbox" (no
quotes) at the end of your ~/.xinitrc or ~/.xsession file. The advantage of putting
Blackbox at the end of the file is that the X Server will shutdown when you exit Blackbox.
Blackbox can also be started from the command line of a terminal program like xterm in an
X session that does not already have a window manager running.

On startup, Blackbox will look for ~/.blackboxrc and use the resource session.menuFile to
determine where to get the menu for the session. If this file is not found Blackbox will
use /etc/X11/blackbox/blackbox-menu as the menu file. If that fails as well Blackbox will
use a default menu that contains commands to start an xterm as well as restart and exit
the window manager. The other resources available in the ~/.blackboxrc file are discussed
later in this manual under the heading RESOURCE FILE.

On exit, Blackbox writes its current configuration to ~/.blackboxrc.
NOTE:
If ~/.blackboxrc is modified during a Blackbox
session, Blackbox must be restarted with the
"restart" command on the main menu or the changes
will be lost on exit. Restart causes Blackbox to
re-read ~/.blackboxrc and apply the changes immediately.
Blackbox can be exited by selecting "exit" on the main menu (discussed shortly), killing
it gently from a terminal or by the X Window System shutdown hot key combo
Ctrl+Alt+BackSpace.

USING BLACKBOX

A three button mouse has the following functions when clicking on the root window:

Button Two (Middle Button)
Open workspace menu

Button Three (Right Button)
Open main menu

Note that Button One (Left Button) is not used.

Main Menu
The default installation assumes you have a number of common X Window System
programs in their typical locations. The default menu is defined by a plain text
file named 'menu'. It is heavily commented and covers a number of details of menu
file syntax. This file can also be edited graphically by using the extension
program bbconf which makes menu creation very easy. Menu file syntax is discussed
later in this manual.
Caveat:
Menus can run arbitrary command lines, but
if you wish to use a complex command line
it is best to place it in a shell script.
Remember to put #!/bin/sh on the first
line and chmod 755 on the file to make it
executable.

Workspace Menu
This menu gives the user control of the workspace system. The user can create a new
workspace, remove the last workspace or go to an application via either the icon
menu or a workspace entry. Workspaces are listed by name. Clicking on the
workspace name will take you to that workspace with focus on the program under the
mouse. If there are programs already running in the workspace, they will appear in
a pop-out menu. Clicking on the application name will jump to the workspace and
focus that application. If a middle click is used the window will be brought to the
current workspace.

Blackbox uses an external program, bbpager, to provide a traditional, graphical
paging interface to the workspace system. Many Blackbox users run another extension
program - bbkeys - to provide keyboard shortcuts for workspace control.
Caveat:
To name a workspace the user must right
click on the toolbar, select "Edit current
workspace name," type the workspace name,
And_Press_Enter to finish.
Workspaces can also be named in the .blackboxrc file as described in RESOURCES.

The Slit
The Slit provides a user positionable window for running utility programs called
"dockapps". To learn more about dockapps refer to the web sites mentioned in the
Description. Dockapps automatically run in the slit in most cases, but may require
a special command switch. Often, -w is used for "withdrawn" into the slit.

gkrellm is a very useful and modern dockapp that gives the user near real time
information on machine performance. Other dockapps include clocks, notepads,
pagers, key grabbers, fishbowls, fire places and many, many others.

Only mouse button three is captured by the Blackbox slit. This menu allows the user
to change the position of the slit, and sets the state of Always on top, and Auto
hide. These all do what the user expects.

Caveat:
When starting Dockapps from an external script
a race condition can take place where the shell
rapidly forks all of the dockapps, which then
take varied and random times to draw themselves
for the first time. To get the dockapps to start
in a given order, follow each dockapp with
sleep 2; This ensures that each dockapp is placed
in the correct order by the slit.
i.e.
#!/bin/sh
speyes -w & sleep 2
gkrellm -w & sleep 2

The Toolbar
The toolbar provides an alternate method for cycling through multiple workspaces
and applications. The left side of the toolbar is the workspace control, the center
is the application control, and the right side is a clock. The format of the clock
can be controlled as described under RESOURCES.

Mouse button 3 raises a menu that allows configuration of the toolbar. It can be
positioned either at the top or the bottom of the screen and can be set to auto
hide and/or to always be on top.

Caveat:
The toolbar is a permanent fixture. It
can only be removed by modifying the source and
rebuilding, which is beyond the scope of this
document. Setting the toolbar to auto hide is
the next best thing.

Window Decorations
Window decorations include handles at the bottom of each window, a title bar, and
three control buttons. The handles at the bottom of the window are divided into
three sections. The two corner sections are resizing handles The center section is
a window moving handle. The bottom center handle and the title bar respond to a
number of mouse clicks and key + mouse click combinations. The three buttons in the
title bar, left to right, are iconify, maximize, and close. The resize button has
special behavior detailed below.

Button One (Left Button)
Click and drag on titlebar to move or resize from bottom corners. Click the
iconify button to move the window to the icon list. Click the maximize button to
fully maximize the window. Click the close button to close the window and
application. Double-Click the title bar to shade the window.

Alt + Button One
Click anywhere on client window and drag to move the window.

Button Two (Middle Button)
Click the titlebar to lower the window. Click the maximize button to maximize the
window vertically.

Button Three (Right Button)
Click on title bar or bottom center handle pulls down a control menu. Click the
maximize button to maximize the window horizontally.

Alt + Button Three
Click anywhere on client window and drag to resize the window.

The control menu contains:

Send To ...
Button One (Left Button)
Click to send this window to another workspace.
Button Two (Middle Button)
Click to send this window to another workspace, change
to that workspace and keep the application focused.
as well.

Shade This is the same action as Double-Click with Button One.

Iconify
Hide the window. It can be accessed with the icon menu.

Maximize
Toggle window maximization.

Raise Bring window to the front above the other windows and
focus it.

Lower Drop the window below the other ones.

Stick Stick this window to the glass on the inside of
the monitor so it does not hide when you change
workspaces.

Kill Client
This kills the client program with -SIGKILL (-9)
Only use this as a last resort.

Close Send a close signal to the client application.

STYLES

Styles are a collection of colors, fonts, and textures that control the appearance of
Blackbox. These characteristics are recorded in style files. The default system style
files are located in /usr/share/blackbox/styles. The menu system will identify the style
by its filename, and styles can be sorted into different directories at the user's
discretion.

There are over 700 styles available for Blackbox. The official distribution point for
Blackbox styles is

http://blackbox.themes.org/

All themes should install by simply downloading them to ~/.blackbox/ then unzip it, and
de-tar it.

On open Unixes this will be:

tar zxvf stylename.tar.gz

On commercial Unixes this will be something like:

gunzip stylename.tar.gz && tar xvf stylename.tar

Check your system manuals for specifics or check with your network administrator.

An entry should appear in the styles menu immediately.
Security Warning
Style files can execute shell scripts and other
executables. It would is wise to check the
rootCommand in the style file and make sure that
it is benign.

Things that go wrong.

1. The theme is pre Blackbox 0.51.
Style file syntax changed with version 0.51

2. The style tarball was formatted incorrectly.
Some styles use the directories ~/.blackbox/Backgrounds and ~/.blackbox/Styles

This can fixed by adding a [stylemenu] (~/.blackbox/Styles) to your menu file. To
be a complete purist, hack the style file with the correct paths and move the files
into the correct directories

3. The rootCommmand line is broken.
The rootCommand line in the style file will run an arbitrary executable. It is
important that this executable be set to bsetbg to maintain portability between
systems with different graphics software. In addition bsetbg can execute a shell
script and do it in a portable fashion as well.

The documented method for creating styles is as follows:

1. Create or acquire the background for the style if
it will not be using bsetroot to draw a patterned background for the root window.

NOTE:
Blackbox runs on a wide variety
of systems ranging from PCs with 640x480 256 color
displays to ultra high speed workstations with 25"
screens and extreme resolution. For best results a
style graphic should be at least 1024x768.

2. Create a style file.
The best way to do this is to make a copy of a similar style and then edit it.

The style file is a list of X resources and other external variables. Manipulating
these variables allows users to completely change the appearance of Blackbox. The
user can also change the root window image by using the wrapper program bsetbg.

bsetbg knows how to use a number of programs to set the root window image. This
makes styles much more portable since various platforms have different graphics
software. For more info see bsetbg (1).

3. Background images should be placed in
~/.blackbox/backgrounds The style file should be placed in ~/.blackbox/styles any
other information about the style should be placed in
~/.blackbox/about/STYLE_NAME/. This would include README files, licenses, etc.

Previous versions of Blackbox put backgrounds and styles in different directories.
The directories listed above are the only officially supported directories.
However you may put them whereever you like as long as you update your menu file so
it knows where to find your styles.

4. To create a consistent experience and to ensure
portability between all systems it is important to use the following format to
create your style archive.

first create a new directory named after your style NEW_STYLE

In this directory create the directories
backgrounds
styles
about/NEW_STYLE
Next put everything for the theme in these locations. Finally type

tar cvzf NEW_STYLE.tar.gz *

If you are using commercial Unix you may need to use gzip and tar separately.

Now when a user downloads a new style file she knows that all she has to do is put
the tarball in her Blackbox directory, unzip->un-tar it and then click on it in her
style menu.

Style File Syntax and Details

By far the easiest way to create a new style is to use bbconf. bbconf allows
complete control of every facet of style files and gives immediate updates of the
current style as changes are made.

The style file format is not currently documented in a man page. There is a readme
document included with the Blackbox source containing this information.

MENU FILE

The default menu file is installed in /etc/X11/blackbox/blackbox-menu. This menu can be
customized as a system default menu or the user can create a personal menu.

To create a personal menu copy the default menu to a file in your home directory. Then,
open ~/.blackboxrc and add or modify the resource session.menuFile: ~/.blackbox/menu

Next, edit the new menu file. This can be done during a Blackbox session and the menu will
automatically be updated when the code checks for file changes.

The default menu included with Blackbox has numerous comments describing the use of all
menu commands. Menu commands follow this general form:

[command] (label|filename) {shell command|filename}

Blackbox menu commands:

# string...
Hash (or pound or number sign) is used as the comment delimiter. It can be used as
a full line comment or as an end of line comment after a valid command statement.

[begin] (string)
This tag is used only once at the beginning of the menu file. "string" is the name
or description used at the top of the menu.

[end]
This tag is used at the end of the menu file and at the end of a submenu block.

[exec] (label string) {command string}
This is a very flexible tag that allows the user to run an arbitrary shell command
including shell scripts. If a command is too large to type on the command line by
hand it is best to put it in a shell script.

[nop] (label string)
This tag is used to put a divider in the menu. label string is an optional
description.

[submenu] (submenu name) {title string}
This creates a sub-menu with the name submenu name and if given, the string title
string will be the title of the pop up menu itself.

[include] (filename)
This command inserts filename into the menu file at the point at which it is
called. filename should not contain a begin end pair. This feature can be used to
include the system menu or include a piece of menu that is updated by a separate
program.

[stylesdir] (description) (path)
Causes Blackbox to search path for style files. Blackbox lists styles in the menu
by their file name as returned by the OS.

[stylesmenu] (description) {path}
This command creates a submenu with the name description with the contents of path.
By creating a submenu and then populating it with stylesmenu entries the user can
create an organized library of styles.

[workspaces] (description)
Inserts a link into the main menu to the workspace menu. If used, description is an
optional description.

[config] (label)
This command causes Blackbox to insert a menu that gives the user control over
focus models, dithering and other system preferences.

[reconfig] (label) {shell command}
The reconfig command causes Blackbox to reread its configuration files. This does
not include ~/.blackboxrc which is only reread when Blackbox is restarted. If shell
command is included Blackbox will run this command or shell script before rereading
the files. This can be used to switch between multiple configurations

[restart] (label) {shell command}
This command is actually an exit command that defaults to restarting Blackbox. If
provided shell command is run instead of Blackbox. This can be used to change
versions of Blackbox. Not that you would ever want to do this but, it could also be
used to start a different window manager.

[exit] (label)
Shuts down Blackbox. If Blackbox is the last command in your ~/.xinitrc file, this
action will also shutdown X.
Here is a working example of a menu file:
[begin] (MenuName)
[exec] (xterm) {xterm -ls -bg black -fg green}
[submenu] (X utilities)
[exec] (xcalc) {xcalc}
[end]
[submenu] (styles)
[stylesmenu] (built-in styles) {/usr/share/blackbox/styles}
[stylesmenu] (custom styles) {~/.blackbox/styles}
[end]
[workspaces] (workspace list)
[config] (configure)
[reconfig] (config play desktop) {play-config-blackbox}
[reconfig] (config work desktop) {work-config-blackbox}
[restart] (start Blackbox beta 7) {blackbox-beta7}
[restart] (start Blackbox cvs) {blackbox-cvs}
[restart] (restart)
[exit] (exit)
[end]

RESOURCE FILE

$HOME/.blackboxrc These options are stored in the ~/.blackboxrc file. They control
various features of Blackbox and most can be set from menus. Some of these can only be set
by editing .blackboxrc directly.

NOTE: Blackbox only reads this file during start up. To make changes take effect during a
Blackbox session the user must choose "restart" on the main menu. If you do not do so,
your changes will be lost when Blackbox exits.

Some resources are named with a <num> after screen. This should be replaced with the
number of the screen that is being configured. The default is 0 (zero).

Menu Configurable (Slit Menu):
Right click (button 3) on the slit border.

session.screen<num>.slit.placement SEE BELOW
Determines the position of the slit. Certain combinations of slit.placement with
slit.direction are not terribly useful, i.e. TopCenter with Vertical direction puts the
slit through the middle of your screen. Certainly some will think that is cool if only
to be different...
Default is CenterLeft.
[ TopLeft | TopCenter | TopRight |
CenterLeft | | CenterRight |
BottomLeft | BottomCenter | BottomRight ]

session.screen<num>.slit.direction [Horizontal|Vertical]
Determines the direction of the slit.
Default is Vertical.

session.screen<num>.slit.onTop [True|False]
Determines whether the slit is always visible over windows or if the focused window can
hide the slit.
Default is True.

session.screen<num>.slit.autoHide [True|False]
Determines whether the slit hides when not in use. The session.autoRaiseDelay time
determines how long you must hover to get the slit to raise and how long it stays
visible after mouse out.
Default is False.

Menu Configurable (Main Menu):

session.screen<num>.focusModel SEE BELOW
Sloppy focus (mouse focus) is the conventional X Window behavior and can be modified
with AutoRaise or Click-Raise.

AutoRaise causes the window to automatically raise after session.autoRaiseDelay
milliseconds.

ClickRaise causes the window to raise if you click anywhere inside the client area of
the window.

Sloppy focus alone requires a click on the titlebar, border or lower grip to raise the
window.

ClickToFocus requires a click on a Blackbox decoration or in the client area to focus
and raise the window. ClickToFocus cannot be modified by AutoRaise or ClickRaise.
Default is SloppyFocus
[SloppyFocus [[AutoRaise & ClickRaise] |
[AutoRaise | ClickRaise]] |
ClickToFocus]

session.screen<num>.windowPlacement SEE BELOW
RowSmartPlacement tries to fit new windows in empty space by making rows. Direction
depends on session.screen<num>.rowPlacementDirection

ColSmartPlacement tries to fit new windows in empty space by making columns Direction
depends on session.screen<num>.colPlacementDirection

CascadePlacement places the new window down and to the right of the most recently
created window.
Default is RowSmartPlacement.
[RowSmartPlacement | ColSmartPlacement | CascadePlacement]

session.screen<num>.rowPlacementDirection [LeftToRight|RightToLeft]
Determines placement direction for new windows.
Default is LeftToRight.

session.screen<num>.colPlacementDirection [TopToBottom|BottomToTop]
Determines placement direction for new windows.
Default is TopToBottom.

session.imageDither [True|False]
This setting is only used when running in low color modes. Image Dithering helps one to
show an image properly even if there are not enough colors available in the system.
Default is False.

session.opaqueMove [True|False]
Determines whether the window's contents are drawn as it is moved. When False the
behavior is to draw a box representing the window.
Default is False.

session.screen<num>.fullMaximization [True|False]
Determines if the maximize button will cause an application to maximize over the slit
and toolbar.
Default is False.

session.screen<num>.focusNewWindows [True|False]
Determines if newly created windows are given focus after they initially draw
themselves.
Default is False.

session.screen<num>.focusLastWindow [True|False]
This is actually "when moving between workspaces, remember which window has focus when
leaving a workspace and return the focus to that window when I return to that
workspace."
Default is False.

session.screen<num>.disableBindingsWithScrollLock [True|False]
When this resource is enabled, turning on scroll lock keeps Blackbox from grabbing the
Alt and Ctrl keys that it normally uses for mouse controls. This feature allows users
of drawing and modeling programs which use keystrokes to modify mouse actions to
maintain their sanity. *NOTE* this has _no_ affect on bbkeys. If you need bbkeys to
also behave this way it has a similar option in its config file. Refer to the bbkeys
manpage for details.
Default is False.

Menu Configurable (Workspace Menu):
Middle click (button 2) on the root window (AKA Desktop) to reach this menu

session.screen<num>.workspaces [integer]
Workspaces may be created or deleted by middle clicking on the desktop and choosing
"New Workspace" or "Remove Last". After creating a workspace, right click on the
toolbar to name it.
Default is 1

Menu Configurable (Toolbar Menu):

session.screen<num>.workspaceNames [string[, string...]]
Workspaces are named in the order specified in this resource. Names should be delimited
by commas. If there are more workspaces than explicit names, un-named workspaces will
be named as "Workspace [number]".
Default is
Workspace 1.

session.screen<num>.toolbar.placement SEE BELOW
Set toolbar screen position.
Default is BottomCenter
[ TopLeft | TopCenter | TopRight |
BottomLeft | BottomCenter | BottomRight ]

session.screen<num>.toolbar.onTop [True|False]
Determines whether the toolbar is always visible over windows or if the focused window
can hide the toolbar.
Default is True.

session.screen<num>.toolbar.autoHide [True|False]
Determines whether the toolbar hides when not in use. The session.autoRaiseDelay time
determines how long you must hover to get the toolbar to raise, and how long it stays
visible after mouse out.
Default is False.

Configurable in ~/.Blackboxrc only:

session.screen<num>.toolbar.widthPercent [1-100]
Percentage of screen used by the toolbar. A number from 1-100 that sets the width of
the toolbar. 0 (zero) does not cause the toolbar to disappear, instead the toolbar is
set to the default. If you want to lose the toolbar there are patches that can remove
it.
Default is 66.

session.screen<num>.strftimeFormat [string]
A C language date format string, any combination of specifiers can be used. The default
is %I:%M %p which generates a 12 hour clock with minutes and an am/pm indicator
appropriate to the locale.
24 hours and minutes %H:%M
12 hours and minute %I:%M %p
month/day/year %m/%d/%y
day/month/year %d/%m/%y
Default is hours:minutes am/pm
See
strftime 3
for more details.

session.screen<num>.dateFormat [American|European]
NOTE: Only used if the strftime() function is not available on your system.
Default is American, (mon/day/year).

session.screen<num>.clockFormat [12/24]
NOTE: Only used if the strftime() function is not available on your system.
Default is 12-hour format.

session.screen<num>.edgeSnapThreshold [integer]
When set to 0 this turns off edge snap. When set to one or greater edge snap will cause
a window that is being moved to snap to the nearest screen edge, the slit, or or the
toolbar. Windows will not snap to each other. The value represents a number in pixels
which is the distance between the window and a screen edge which is required before the
window is snapped to the screen edge. If you prefer this functionality values between
6 - 10 work nicely.
Default value is 0

session.menuFile [filepath]
Full path to the current menu file.
Default is /etc/X11/blackbox/blackbox-menu

session.colorsPerChannel [2-6]
The number of colors taken from the X server for use on pseudo color displays. This
value must be set to 4 for 8 bit displays.
Default is 4.

session.doubleClickInterval [integer]
This is the maximum time that Blackbox will wait after one click to catch a double
click. This only applies to Blackbox actions, such as double click shading, not to the
X server in general.
Default is 250 milliseconds.

session.autoRaiseDelay [integer]
This is the time in milliseconds used for auto raise and auto hide behaviors. More than
about 1000 ms is likely useless.
Default is 250 millisecond.

session.cacheLife [integer]
Determines the maximum number of minutes that the X server will cache unused
decorations.
Default is 5 minutes

session.cacheMax [integer]
Determines how many kilobytes that Blackbox may take from the X server for storing
decorations. Increasing this number may enhance your performance if you have plenty of
memory and use lots of different windows.
Default is 200 Kilobytes

ENVIRONMENT

HOME Blackbox uses $HOME to find its .blackboxrc rc file and its .blackbox directory for
menus and style directories.

DISPLAY
If a display is not specified on the command line, Blackbox will use the value of
$DISPLAY.

Use blackbox online using onworks.net services
