NAME
twm - a window manager for X11 (Tom's Window Manager)
SYNTAX
twm [-display display]
DESCRIPTION
This program is currently unsupported. It is provided
in the GSE demos directory as a user convenience.
twm is a window manager client application of the
window server.
twm was written to incorporate some of the desirable
features of the wm and uwm window managers. twm puts a
title bar on and reparents each window. The title bar
contains the window's name and three buttons. When a
pointer-button-press event is detected in any of these
title bar buttons, a certain action is performed.
The left-most title bar button, which looks like a
window pane, causes the window to be iconified. The
right-most title bar button, with the right-angles, is
the resize button. The resize function is identical to
the window resize function of the wm window manager.
The other title bar button represents a keyboard; a
button click here causes the input focus to stay
directed to this window until the f.unfocus function is
executed or another window is selected to get input
focus; by default, the input focus follows the mouse or
other pointing device. The title bar also becomes
highlighted on the window that currently has the input
focus.
When twm is invoked, it attempts to read a twm start-up
file. The name of the twm start-up file is
$HOME/.twmrc.
The twm start-up file has three logical sections: the
variables section, the buttons section, and the menus
section. The variables section must come first,
followed by either the buttons section or the menus
section.
All variables and keywords may be entered in any
combination of upper- and lowercase letters. Functions
must be entered in lowercase. A pound sign (#)
character in the start-up file indicates a comment,
which is terminated by the newline character. A string
in the start-up file is a series of characters enclosed
in double quotes (").

VARIABLES
Variables must be entered first, at the top of the
start-up file. Variables are initialized only once,
when twm begins execution. They will not be affected
when a subsequent f.twmrc function is executed. It is
probably a good idea to initialize the color variables
first.
Several variables take filenames as arguments.
Filenames are processed as follows: twm checks to see
if the first character in the filename is a tilde ( );
~
if it is, twm prepends the user's HOME environment
variable to the filename. In the case of variables
requiring bitmap files, if the above expansion does not
produce a path to a valid bitmap file, the following
steps are taken: if the ICONDIRECTORY variable has
been set and the filename does not start with a slash
(/), the ICONDIRECTORY variable is prepended to the
filename. If that path does not produce a valid bitmap
file, the string usr/include/X11/bitmaps/ is prepended
to the original filename.
The twm variables are:
AutoRaise { list }
This variable is a list of window names that will
automatically raise to the top of the stacking
order whenever the pointer enters the window. The
window names in the list are the first characters
in the window name to check for. For example:
AutoRaise
{
"xterm"
"xclock"
}
The above list contains two names which will match
window names beginning with the string xterm or
xclock. The following window names will match and
be in autoraise mode: xterm, xterm_iguana, xclock.
BorderColor string
This variable sets the color of the border to
placed around all noniconified windows. It can
only be specified inside of a Color or Monochrome
list. The default is black.
BorderTileForeground string
This variable sets the foreground color of the grey
bitmap used in nonhighlighted borders. It can only
be specified inside of a Color or Monochrome list.
- 2 -
TWM(1) (X Utilities) TWM(1)
The default is black.
BorderTileBackground string
This variable sets the background color of the grey
bitmap used in nonhighlighted borders. It can only
be specified inside of a Color or Monochrome list.
The default is white.
BorderWidth pixels
This variable specifies the width in pixels of of
the border surrounding all windows. The default is
2.
Color { colors }
This variable is a list of color assignments to be
made if the default display has a depth greater
than 1, that is, has the ability to display more
than black and white. For example:
Color
{
BorderColor "red"
TitleForeground "yellow"
TitleBackground "blue"
}
The various color variables may be found in this
section of the manual page. There is also a
Monochrome list of colors that may be specified.
This enables you to use the same initialization
file on a color or monochrome display.
DecorateTransients
This variable causes twm to put a title bar on
transient windows. By default, transient windows
will not be reparented.
DefaultFunction function
This variable defines a default window manager
function to be performed if no function is assigned
to a combination of modifier keys and mouse
buttons. A useful function to execute might be
f.beep.
DontIconifyByUnmapping { list }
This variable is a list of windows not to iconify
by simply unmapping the window. This may be used
when specifying IconifyByUnmapping to selectively
choose windows that will iconify by mapping an icon
window.
DontMoveOff
- 3 -
TWM(1) (X Utilities) TWM(1)
If this variable is set, windows will not be
allowed to be moved off the display.
ForceIcons
This variable is only meaningful if a Icons list is
defined. It forces the icon bitmaps listed in the
Icons list to be used as window icons even if
client programs supply their own icons. The
default is to not force icons.
Icons { list }
This variable is a list of window names and bitmap
filenames to be used as icons. For example:
Icons
{
"xterm""xterm.icon"
"xfd" "xfd_icon"
}
xterm and xfd are added to a list that is searched
when the client window is reparented by twm. The
window names specified are just the first portion
of the name to match. In the above example, xterm
would match xtermfred and also xterm blob. The
client window names are checked against those
specified in this list, in addition to the class
name of the client if it is specified. By using
the class name, all xterm windows can be given the
same icon by the method used above even if the
names of the windows are different.
IconBackground string
This variable sets the background color of icons.
It can only be specified inside of a Color or
Monochrome list. The default is white.
IconBorderColor string
This variable sets the color of the border around
icons. It can only be specified inside of a Color
or Monochrome list. The default is black.
IconDirectory string
This variable names the directory in which to
search for icon bitmap files. The default is to
have no icon directory.
IconFont string
This variable names the font to be displayed within
icons. The default is 8x13.
IconForeground string
- 4 -
TWM(1) (X Utilities) TWM(1)
This variable sets the foreground color of icons.
It can only be specified inside of a Color or
Monochrome list. The default is black.
IconifyByUnmapping
This variable causes twm to iconify windows by
simply unmapping them. The icon window will not be
made visible. This variable can be used in
conjunction with the DontIconifyByUnmapping list.
The default is to iconify by unmapping the window
and mapping a separate icon window.
IconManagerDontShow { list }
This variable is a list of window names that will
not be displayed in the icon manager window. This
may be useful in specifying windows that are rarely
iconified such as xclock.
IconManagerBackground string
This variable sets the background color of the icon
manager window. It can only be specified inside of
a Color or Monochrome list. The default is white.
IconManagerForeground string
This variable sets the foreground color of the icon
manager window. It can only be specified inside of
a Color or Monochrome list. The default is black.
IconManagerGeometry string
This variable sets the geometry of the icon manager
window. string is of the form:
=<width>x<height>{+-}<xoffset>{+-}<yoffset>
The height of the icon manager window is not very
important because the height of the window changes
as windows are created and destroyed.
MenuBackground string
This variable sets the background color of menus.
It can only be specified inside of a Color or
Monochrome list. The default is white.
MenuFont string
This variable names the font to be displayed within
menus. The default is 8x13.
MenuForeground string
This variable sets the foreground color of menus.
It can only be specified inside of a Color or
Monochrome list. The default is black.
- 5 -
TWM(1) (X Utilities) TWM(1)
MenuShadowColor string
This variable sets the color of the shadow behind
pull-down menus. It can only be specified inside
of a Color or Monochrome list. The default is
black.
MenuTitleBackground string
This variable sets the background color for f.title
entries in menus. It can only be specified inside
of a Color or Monochrome list. The default is
white.
MenuTitleForeground string
This variable sets the foreground color for f.title
entries in menus. It can only be specified inside
of a Color or Monochrome list. The default is
black.
Monochrome { colors }
This variable is a list of color assignments to be
made if the default display has a depth equal to
one, in other words, it can only display black and
white pixels. For example:
Monochrome
{
BorderColor "black"
TitleForeground "black"
TitleBackground "white"
}
The various color variables may be found in this
section of the manual page. There is also a Color
list of colors that may be specified. This enables
you to use the same initialization file on a color
or monochrome display.
NoBackingStore
twm menus attempt to use backing store to minimize
menu repainting. If your server has implemented
backing store but you would rather not use this
feature, this variable will disable twm from using
backing store.
NoHighlight [ { list } ]
This variable turns off border highlighting. An
optional list may be specified with window names to
selectively turn off border highlighting. The
default is to highlight the borders of all windows
when the cursor enters the window. When the border
is highlighted, it will be drawn in the current
BorderColor. When the border is not highlighted,
- 6 -
TWM(1) (X Utilities) TWM(1)
it will be rendered with a grey bitmap using the
current BorderTileForeground and
BorderTileBackground colors.
NoSaveUnder
twm menus attempt to use save-unders to minimize
window repainting following menu selections. If
your server has implemented save-unders but you
would rather not use this feature, this variable
will disable twm from using save-unders.
NoTitle [ { list } ]
This variable is a list of window names that will
not have a title bar created for them. If NoTitle
is specified with no window name list, twm will not
put title bars on any windows. The list of windows
and how they match window names is exactly like the
AutoRaise variable.
NoIconName { list }
This variable is a list of window names whose icon
will not contain the name of the icon. This is
useful for windows that create their own icons and
do not want to have the icon cluttered up with the
name of the icon. For example, xcalc creates an
icon that looks like a calculator. There is no
need to have the name of the window on the icon,
since the icon inherently describes what the icon
is. If no icon is specified by the user, then the
default icon will be created (with the name) even
if NoIconName is specified for that window. The
list of windows and how they match window names is
exactly like the AutoRaise variable.
NoRaiseOnDeiconify
If this variable is specified, windows will not be
raised to the top of the stacking order when
deiconified.
NoRaiseOnMove
If this variable is specified, windows will not be
raised to the top of the stacking order following a
move.
NoRaiseOnResize
If this variable is specified, windows will not be
raised to the top of the stacking order following a
resize.
NoTitleFocus
If this variable is specified, input focus will not
be directed to windows when the pointer is in the
- 7 -
TWM(1) (X Utilities) TWM(1)
title bar. The default is to focus input to a
client when the pointer is in the title bar.
RandomPlacement
This causes windows with no specified geometry to
be placed on the display in a random (kind of)
position when they are created. The default is to
allow the user to position the window
interactively.
ResizeFont string
This variable names the font to be displayed in the
dimensions window during window resize operations.
The default is fixed.
TitleFont string
This variable names the font to be displayed within
the window title bar. Note that the title bar is
only 17 pixels in height, so the largest practical
font would be something like 9x15. The default is
8x13.
ReverseVideo
This variable causes twm to display white
characters on a black background, rather than black
characters on white. This variable does not really
do much now that you can specify individual colors.
ShowIconManager
This variable causes the icon manager window to be
displayed when twm is started. The default is to
not display the icon manager window.
TitleBackground string
This variable sets the background color for the
title bars. It can only be specified inside of a
Color or Monochrome list. The default is white.
TitleForeground string
This variable sets the foreground color for the
title bars. It can only be specified inside of a
Color or Monochrome list. The default is black.
UnknownIcon string
This variable specifies the file name of a bitmap
format file to be used as the default icon. This
bitmap will be used for the icon of all clients
which do not provide an icon bitmap and are not
listed in the Icons list. The default is to use no
bitmap.
WarpCursor
- 8 -
TWM(1) (X Utilities) TWM(1)
This variable causes the pointer cursor to be
warped to a window which is being deiconified. The
default is to not warp the cursor.
WindowFunction function
This variable is the function to perform when a
window is selected from the TwmWindows menu. If
this variable is not set, a window selected from
the TwmWindows menu will be deiconified (if it is
an icon) and then raised to the top of the window
stacking order.
Zoom [ count ]
This variable causes a series of outlines to be
drawn when a window is iconified or deiconified.
The optional count is a number which will be the
number of outlines to be drawn. The default is to
not draw the outlines. The default outline count
is 8.
BUTTONS SECTION
The buttons section of the start-up file contains
definitions of functions to perform when pointer
buttons or specific keyboard keys are pressed.
Functions are assigned either to a pointer button, a
keyboard key, or a menu entry. Functions are assigned
to pointer buttons as follows:
Buttonn = keys : context : function
The n following Button can be a number between 1 and 5
to indicate which pointer button the function is to be
tied to. The keys field is used to specify which
modifier keys must be pressed in conjunction with the
pointer button. The keys field may contain any
combination of the letters s, c, and m, which stand for
Shift, Control, and Meta, respectively.
The context field specifies the context in which to
look for the button press. Valid contexts are: icon,
root, title, frame, window, and iconmgr. The function
field specifies the window manager function to perform.
It is important to note that the iconmgr context is
only used when a pointer button is pressed in an icon
manager window and the window is an icon. By default,
a button press in an icon manager window while the
window is not iconic, will turn the window into an
icon.
EXAMPLES
Button2 = : title : f.move # 1
Button1 = : root : f.menu "menu 1" # 2
- 9 -
TWM(1) (X Utilities) TWM(1)
Button1 = m : icon : f.menu "icon menu 1" # 3
Button3 = msc : window : f.menu "menu3 1" # 4
Line 1 specifies that when pointer button 2 is pressed
in the title bar with no modifier keys pressed, the
f.move function is to be executed. Line 2 specifies
that when pointer button 1 is pressed in the root
window with no modifier keys pressed, the menu "menu 1"
is popped up. Line 3 specifies that when pointer
button 1 is pressed in an icon window with the meta key
pressed, the menu "icon menu 1" is popped up. Line 4
specifies that when pointer button 3 is pressed in a
client window with the shift, control, and meta keys
pressed, the menu "menu 3" is popped up.
Function Key Specifications
twm allows you execute functions when any key on the
keyboard is pressed. The specification of a function
key is exactly like the button specification described
above, except instead of Button[1-5], a function key
name in double quotes is used. In addition to the
normal contexts that may be specified, a window name
may be used, and the function will be applied to all
windows matching the name. For example:
"F1" = : window : f.iconify
"F2" = m : root : f.refresh
"F3" = m : "window_name": f.iconify
Keyboard key names can be found in
/usr/include/X11/keysymdef.h. Simply remove the XK_
and you have the name that the X server will recognize.
TWM Functions
! string
causes string to be sent to /bin/sh for execution.
^ string
causes string followed by a newline character to be
placed in the window server's cut buffer.
= string
causes string to be sent to the window when the
described function key is pressed. This allows the
function keys to be programmed. Control characters
may be used in the string. No newline is
concatenated to the string; this is the
responsibility of the user.
f.beep
causes the bell of the workstation to be sounded.
- 10 -
TWM(1) (X Utilities) TWM(1)
f.circledown
causes the top window that is obscuring another
window to drop to the bottom of the stack of
windows.
f.circleup
raises the lowest window that is obscured by other
windows.
f.cutfile
takes the contents of the window server's cut
buffer and uses it as a filename to read into the
server's cut buffer.
f.deiconify
deiconifies a window. If the window is not an
icon, this function does nothing. If executed from
a menu, the cursor is changed to a dot and the next
window that receives a button press will be the
window that is deiconified.
f.destroy
allows you to destroy a window client. If executed
from a menu, the cursor is changed to a skull and
crossbones and the next window to receive a button
press will be destroyed.
f.file string
assumes string is a filename. This file is read
into the window server's cut buffer.
f.focus
implements the same function as the keyboard focus
button in the title bar. If executed from a menu,
the cursor is changed to a dot and the next window
to receive a button press will gain the input
focus.
f.forcemove
allows you to move a window. If DontMoveOff is
set, f.forcemove allows you to move a window
partially off the display. If executed from a
menu, the cursor is changed to a double arrow and
the next window that receives a button press will
be the window that is moved.
f.fullzoom
resizes the current window to the full size of your
display. It is a toggle function so it is really a
fullzoom/unfullzoom function. To undo the fullzoom,
you invoke f.fullzoom again, similar to f.iconify.
If executed from a menu, the cursor is changed to a
- 11 -
TWM(1) (X Utilities) TWM(1)
dot and the next window that receives a button
press will be the window that is
fullzoomed/unfullzoomed.
f.function string
executes the user defined function stream specified
by string. A function stream is zero or more twm
functions that will be executed in order as if they
were a single function. To define a function
stream the syntax is:
Function "function name"
{
function
function
.
.
.
function
}
For example:
Function "raise-n-focus"
{
f.raise
f.focus
}
f.hideiconmgr
causes the icon manager window to become unmapped
(not visible).
f.iconify
implements the same function as the iconify button
in the title bar. If executed from a menu, the
cursor is changed to a dot and the next window to
receive a button press will be iconified or
deiconified depending on the current state of the
window.
f.lower
lowers the window to the bottom of the stacking
order. If executed from a menu, the cursor is
changed to a dot and the next window that receives
a button press will be the window that is lowered.
f.menu string
assigns the pull-down menu named string to a
pointer button. If this function is used as an
entry in a pull-down menu a pull-right menu will be
- 12 -
TWM(1) (X Utilities) TWM(1)
assigned to the menu entry.
f.move
allows you to move a window. If executed from a
menu, the cursor is changed to a double arrow and
the next window that receives a button press will
be the window that is moved.
Double clicking the pointer button tied to this
function causes a constrained move function to be
executed. The pointer will be warped to the center
of the grid.
Moving the pointer to one of the grid lines will
cause the window to begin moving in either an up-
down motion or a left-right motion depending on
which grid line the pointer was moved across.
f.nop
This function does nothing.
f.quit
causes twm to exit. There is no function to exit
the X Window System from a window manager; at
present you must save the X Server's PID in a
variable and send it "kill -TERM". This can easily
be done in twm by the ! function (see example
below).
f.raise
raises the window to the top of the stacking order.
If executed from a menu, the cursor is changed to a
dot and the next window that receives a button
press will be the window that is raised.
f.raiselower
raises the window to the top of the stacking order
if it is obscured in any way. If the window is
unobscured, the window is lowered to the bottom of
the stacking order. If executed from a menu, the
cursor is changed to a dot and the next window that
receives a button press will be the window that is
raised or lowered.
f.refresh
causes all windows to be refreshed.
f.resize
implements the window resize function of the resize
button in the title bar. If executed from a menu,
the cursor is changed to a double arrow and the
next window that receives a button press will be
- 13 -
TWM(1) (X Utilities) TWM(1)
the window that is resized.
f.showiconmgr
causes the icon manager window to become mapped
(visible).
f.restart
This function restarts twm.
f.source string
assumes string is a filename. The file is read and
parsed as a twm startup file. This function is
intended to be used only to rebuild pull-down
menus. No twm variable is changed.
f.title
is to be used as an entry in a pull-down menu. It
centers the menu entry string in a menu entry and
outlines it with a border. This function may be
used more than once in a pull-down menu.
f.twmrc
causes the $HOME/.twmrc file to be reread. This
function is exactly like the f.source function
without having to specify the filename.
f.unfocus
assigns input focus to the root window.
f.version
causes the twm version window to be displayed.
This window will be displayed until a pointer
button is pressed or the pointer is moved from one
window to another.
f.winrefresh
This function is similar to the f.refresh function,
but allows you to refresh a single window. If
executed from a menu, the cursor is changed to a
dot and the next window that receives a button
press will be the window that is refreshed.
f.zoom
This function is similar to the f.fullzoom
function, but resizes the height to the maximum
height of your screen, not the width. It is also a
toggle function like f.iconify and f.fullzoom. If
executed from a menu, the cursor is changed to a
dot and the next window that receives a button
press will be the window that is zoomed/unzoomed.

MENUS SECTION
The menus section is where pull-down menus are defined.
Entries in menus consist of functions as described in
the Buttons Section. The syntax to define a menu is:
Menu "menu name"
{
string function
string function
.
.
.
string function
}
The menu name should be an identical string to one
being used with an f.menu function. Note that the menu
name is case sensitive. The string portion of each
menu entry is the text which will appear in the menu.
The function portion of the menu entry is one of the
functions described in the previous section.
There is a special menu called TwmWindows. When this
menu is pulled down, a list of all window names is
displayed in the menu. Selecting one of these window
names will cause the WindowFunction to be executed. If
WindowFunction has not been set, the window will be
deiconified (if it is an icon) and then raised to the
top of the window stacking order.
ICON MANAGER
The icon manager is a window that contains names of
selected or all windows currently on the display. In
addition to the window name, a small window-pane
iconify button will be displayed to the left of the
name when the window is in an iconic state. If the
window is not currently an icon, a pointer button press
when the pointer is on the window name will cause the
window to be iconified. If the window is iconic, a
pointer button press when the pointer is either on the
window name or on the iconify button will by default,
cause the window to be deiconified. If however, a
button function was specified with a context of
iconmgr, theat function will be executed instead.

WINDOW STARTUP
When a client is started, twm does one of two things.
If the RandomPlacement variable has been set and the
window has not specified an intial geometry, the window
will be placed in a more or less random position in the
display. If the RandomPlacement variable has not been
set and the client has not specified both User
Specified Size hints and User Specified Position hints,
twm will put up a rubberband box indicating the initial
window size.
If pointer button one is pressed, the client window is
created with the window position equal to the current
pointer position. If pointer button two is pressed,
twm allows the window to be resized. The resizing
operation takes place until button two is released.
While the initial positioning of the window is taking
place, twm will place a window in the upper left-hand
corner of the display showing the window's name. If
resizing is taking place, twm will also place a window
in the upper left-hand corner, indicating the current
window size.

BUGS
Pull-right menus may still have some problems. They
may sometimes remain when all pointer buttons have been
released.
Double clicking very fast to get the constrained move
function will sometimes cause the window to move even
though the pointer is not moved.
The window autoraise feature does not work consistently
when the mouse is moved very fast over autoraise
windows.
