TWM(1) AIX TWM(1) NAME twm - Tab Window Manager for the X Window System SYNTAX twm [-display dpy] [-s] [-f initfile] [-v] DESCRIPTION Twm is a window manager for the X Window System. It pro- vides titlebars, shaped windows, several forms of icon management, user-defined macro functions, click-to-type and pointer-driven keyboard focus, and user-specified key and pointer button bindings. This program is usually started by the user's session manager or startup script. When used from xdm(1) or xinit(1) without a session manager, twm is frequently exe- cuted in the foreground as the last client. When run this way, exiting twm causes the session to be terminated (i.e. logged out). By default, application windows are surrounded by a ``frame'' with a titlebar at the top and a special border around the window. The titlebar contains the window's name, a rectangle that is lit when the window is receiving key- board input, and function boxes known as ``titlebuttons'' at the left and right edges of the titlebar. Pressing pointer Button1 (usually the left-most button unless it has been changed with xmodmap) on a titlebutton will invoke the function associated with the button. In the default interface, windows are iconified by clicking (press- ing and then immediately releasing) the left titlebutton (which looks like a Dot). Conversely, windows are deiconi- fied by clicking in the associated icon or entry in the icon manager (see description of the variable ShowIconManager and of the function f.showiconmgr). Windows are resized by pressing the right titlebutton (which resembles a group of nested squares), dragging the pointer over edge that is to be moved, and releasing the pointer when the outline of the window is the desired size. Simi- larly, windows are moved by pressing in the title or highlight region, dragging a window outline to the new loca- tion, and then releasing when the outline is in the desired position. Just clicking in the title or highlight region raises the window without moving it. When new windows are created, twm will honor any size and location information requested by the user (usually through -geometry command line argument or resources for the indivi- dual applications). Otherwise, an outline of the window's default size, its titlebar, and lines dividing the window into a 3x3 grid that track the pointer are displayed. Rev. Release 5 Page 1 TWM(1) AIX TWM(1) Clicking pointer Button1 will position the window at the current position and give it the default size. Pressing pointer Button2 (usually the middle pointer button) and dragging the outline will give the window its current posi- tion but allow the sides to be resized as described above. Clicking pointer Button3 (usually the right pointer button) will give the window its current position but attempt to make it long enough to touch the bottom the screen. OPTIONS Twm accepts the following command line options: -display dpy This option specifies the X server to use. -s This option indicates that only the default screen (as specified by -display or by the DISPLAY environ- ment variable) should be managed. By default, twm will attempt to manage all screens on the display. -f filename This option specifies the name of the startup file to use. By default, twm will look in the user's home directory for files named .twmrc.num (where num is a screen number) or .twmrc. -v This option indicates that twm should print error messages whenever an unexpected X Error event is received. This can be useful when debugging appli- cations but can be distracting in regular use. CUSTOMIZATION Much of twm's appearance and behavior can be controlled by providing a startup file in one of the following locations (searched in order for each screen being managed when twm begins): $HOME/.twmrc.screennumber The screennumber is a small positive number (e.g. 0, 1, etc.) representing the screen number (e.g. the last number in the DISPLAY environment variable host:displaynum.screennum) that would be used to contact that screen of the display. This is intended for displays with multiple screens of differing visual types. $HOME/.twmrc This is the usual name for an individual user's startup file. /usr/lib/X11/twm/system.twmrc If neither of the preceding files are found, twm will look in this file for a default configuration. Rev. Release 5 Page 2 TWM(1) AIX TWM(1) This is often tailored by the site administrator to provide convenient menus or familiar bindings for novice users. If no startup files are found, twm will use the built-in defaults described above. The only resource used by twm is bitmapFilePath for a colon-separated list of directories to search when looking for bitmap files (for more information, see the Athena Widgets manual and xrdb(1)). Twm startup files are logically broken up into three types of specifications: Variables, Bindings, Menus. The Vari- ables section must come first and is used to describe the fonts, colors, cursors, border widths, icon and window placement, highlighting, autoraising, layout of titles, warping, use of the icon manager. The Bindings section usu- ally comes second and is used to specify the functions that should be to be invoked when keyboard and pointer buttons are pressed in windows, icons, titles, and frames. The Menus section gives any user-defined menus (containing func- tions to be invoked or commands to be executed). Variable names and keywords are case-insensitive. Strings must be surrounded by double quote characters (e.g. "blue") and are case-sensitive. A pound sign (#) outside of a string causes the remainder of the line in which the charac- ter appears to be treated as a comment. VARIABLES Many of the aspects of twm's user interface are controlled by variables that may be set in the user's startup file. Some of the options are enabled or disabled simply by the presence of a particular keyword. Other options require keywords, numbers, strings, or lists of all of these. Lists are surrounded by braces and are usually separated by whitespace or a newline. For example: AutoRaise { "emacs" "XTerm" "Xmh" } or AutoRaise { "emacs" "XTerm" "Xmh" } When a variable containing a list of strings representing windows is searched (e.g. to determine whether or not to enable autoraise as shown above), a string must be an exact, case-sensitive match to the window's name name (given by the Rev. Release 5 Page 3 TWM(1) AIX TWM(1) WM_NAME window property), resource name or class name (both given by the WM_CLASS window property). The preceding exam- ple would enable autoraise on windows named ``emacs'' as well as any xterm (since they are of class ``XTerm'') or xmh windows (which are of class ``Xmh''). String arguments that are interpreted as filenames (see the Pixmaps, Cursors, and IconDirectory below) will prepend the user's directory (specified by the HOME environment vari- able) if the first character is a tilde (~). If, instead, the first character is a colon (:), the name is assumed to refer to one of the internal bitmaps that are used to create the default titlebars symbols: :xllogo or :iconify (both refer to the X used for the iconify button), :resize (the nested squares used by the resize button), and :question (the question mark used for non-existent bitmap files). The following variables may be specified at the top of a twm startup file. Lists of Window name prefix strings are indi- cated by win-list. Optional arguments are shown in square brackets: AutoRaise { win-list } This variable specifies a list of windows that should automatically be raised whenever the pointer enters the window. This action can be interactively enabled or disabled on individual windows using the function f.autoraise. AutoRelativeResize This variable indicates that dragging out a window size (either when initially sizing the window with pointer Button2 or when resizing it) should not wait until the pointer has crossed the window edges. Instead, moving the pointer automatically causes the nearest edge or edges to move by the same amount. This allows the resizing of windows that extend off the edge of the screen. If the pointer is in the center of the window, or if the resize is begun by pressing a titlebutton, _t_w_m will still wait for the pointer to cross a window edge (to prevent accidents). This option is particularly useful for people who like the press-drag-release method of sweeping out window sizes. BBBBoooorrrrddddeeeerrrrCCCCoooolllloooorrrr _s_t_r_i_n_g [{ _w_i_n_c_o_l_o_r_l_i_s_t }] This variable specifies the default color of the border to be placed around all non-iconified win- dows, and may only be given within a CCCCoooolllloooorrrr or MMMMoooonnnnoooo---- cccchhhhrrrroooommmmeeee list. The optional _w_i_n_c_o_l_o_r_l_i_s_t specifies a list of window and color name pairs for specifying particular border colors for different types of win- Rev. Release 5 Page 4 TWM(1) AIX TWM(1) dows. For example: BBBBoooorrrrddddeeeerrrrCCCCoooolllloooorrrr "gray50" { "XTerm" "red" "xmh" "green" } The default is "black".

BBBBoooorrrrddddeeeerrrrWWWWiiiiddddtttthhhh _p_i_x_e_l_s This variable specifies the width in pixels of the border surrounding all client window frames if CCCClllliiiieeeennnnttttBBBBoooorrrrddddeeeerrrrWWWWiiiiddddtttthhhh has not been specified. This value is also used to set the border size of windows created by _t_w_m (such as the icon manager). The default is 2. BBBBuuuuttttttttoooonnnnIIIInnnnddddeeeennnntttt _p_i_x_e_l_s This variable specifies the amount by which titlebuttons should be indented on all sides. Posi- tive values cause the buttons to be smaller than the window text and highlight area so that they stand out. Setting this and the TTTTiiiittttlllleeeeBBBBuuuuttttttttoooonnnnBBBBoooorrrrddddeeeerrrrWWWWiiiiddddtttthhhh variables to 0 makes titlebuttons be as tall and wide as possible. The default is 1. CCCClllliiiieeeennnnttttBBBBoooorrrrddddeeeerrrrWWWWiiiiddddtttthhhh This variable indicates that border width of a window's frame should be set to the initial border width of the window, rather than to the value of BBBBoooorrrrddddeeeerrrrWWWWiiiiddddtttthhhh. CCCCoooolllloooorrrr { _c_o_l_o_r_s-_l_i_s_t } This variable specifies a list of color assignments to be made if the default display is capable of displaying more than simple black and white. The Rev. Release 5 Page 5 TWM(1) AIX TWM(1) _c_o_l_o_r_s-_l_i_s_t is made up of the following color vari- ables and their values: DDDDeeeeffffaaaauuuullllttttBBBBaaaacccckkkkggggrrrroooouuuunnnndddd, DDDDeeeeffffaaaauuuulllltttt---- FFFFoooorrrreeeeggggrrrroooouuuunnnndddd, MMMMeeeennnnuuuuBBBBaaaacccckkkkggggrrrroooouuuunnnndddd, MMMMeeeennnnuuuuFFFFoooorrrreeeeggggrrrroooouuuunnnndddd, MMMMeeeennnnuuuu---- TTTTiiiittttlllleeeeBBBBaaaacccckkkkggggrrrroooouuuunnnndddd, MMMMeeeennnnuuuuTTTTiiiittttlllleeeeFFFFoooorrrreeeeggggrrrroooouuuunnnndddd, and MMMMeeeennnnuuuuSSSShhhhaaaa---- ddddoooowwwwCCCCoooolllloooorrrr.

For example: CCCCoooolllloooorrrr { MenuBackground "gray50" MenuForeground "blue" BorderColor "red" { "XTerm" "yellow" } TitleForeground "yellow" TitleBackground "blue" } All of these color variables may also be specified for the MMMMoooonnnnoooocccchhhhrrrroooommmmeeee variable, allowing the same ini- tialization file to be used on both color and mono- chrome displays. CCCCoooonnnnssssttttrrrraaaaiiiinnnneeeeddddMMMMoooovvvveeeeTTTTiiiimmmmeeee _m_i_l_l_i_s_e_c_o_n_d_s This variable specifies the length of time between button clicks needed to begin a constrained move operation. Double clicking within this amount of time when invoking ffff....mmmmoooovvvveeee will cause the window only be moved in a horizontal or vertical direction. Setting this value to 0 will disable constrained moves. The default is 400 milliseconds. CCCCuuuurrrrssssoooorrrrssss { _c_u_r_s_o_r-_l_i_s_t } This variable specifies the glyphs that _t_w_m should use for various pointer cursors. Each cursor may be defined either from the ccccuuuurrrrssssoooorrrr font or from two bit- map files. Shapes from the ccccuuuurrrrssssoooorrrr font may be specified directly as: _c_u_r_s_o_r_n_a_m_e "_s_t_r_i_n_g" where _c_u_r_s_o_r_n_a_m_e is one of the cursor names listed below, and _s_t_r_i_n_g is the name of a glyph as found in the file /usr/include/X11/cursorfont.h (without the ``XC_'' prefix). If the cursor is to be defined from bitmap files, the following syntax is used Rev. Release 5 Page 6 TWM(1) AIX TWM(1) instead: _c_u_r_s_o_r_n_a_m_e "_i_m_a_g_e" "_m_a_s_k" The _i_m_a_g_e and _m_a_s_k strings specify the names of files containing the glyph image and mask in _b_i_t_- _m_a_p(_1) form. The bitmap files are located in the same manner as icon bitmap files. The following example shows the default cursor definitions: CCCCuuuurrrrssssoooorrrrssss { Frame "top_left_arrow" Title "top_left_arrow" Icon "top_left_arrow" IconMgr "top_left_arrow" Move "fleur" Resize "fleur" Menu "sb_left_arrow" Button "hand2" Wait "watch" Select "dot" Destroy "pirate" } DDDDeeeeccccoooorrrraaaatttteeeeTTTTrrrraaaannnnssssiiiieeeennnnttttssss This variable indicates that transient windows (those containing a WM_TRANSIENT_FOR property) should have titlebars.

Release 5 Page 10 TWM(1) AIX TWM(1) location is provided by the client. The _g_e_o_m_s_t_r_i_n_g is a quoted string containing a standard geometry specification. If more than one IIIIccccoooonnnnRRRReeeeggggiiiioooonnnn lines are given, icons will be put into the succeeding icon regions when the first is full. The _v_g_r_a_v argument should be either NNNNoooorrrrtttthhhh or SSSSoooouuuutttthhhh and control and is used to control whether icons are first filled in from the top or bottom of the icon region. Similarly, the _h_g_r_a_v argument should be either EEEEaaaasssstttt or WWWWeeeesssstttt and is used to control whether icons should be filled in from left from the right. Icons are laid out within the region in a grid with cells _g_r_i_d_w_i_d_t_h pixels wide and _g_r_i_d_h_e_i_g_h_t pixels high. IIIIccccoooonnnnssss { _w_i_n-_l_i_s_t } This variable specifies a list of window names and the bitmap filenames that should be used as their icons. For example: IIIIccccoooonnnnssss { "XTerm" "xterm.icon" "xfd" "xfd_icon" } Windows that match ``XTerm'' and would not be iconi- fied by unmapping, and would try to use the icon bitmap in the file ``xterm.icon''.

The optional _s_q_u_e_e_z_e-_l_i_s_t may be used to control the location of the squeezed titlebar along the top of the window. It contains entries of the form: "_n_a_m_e" _j_u_s_t_i_f_i_c_a_t_i_o_n _n_u_m _d_e_n_o_m where _n_a_m_e is a window name, _j_u_s_t_i_f_i_c_a_t_i_o_n is either lllleeeefffftttt, cccceeeennnntttteeeerrrr, or rrrriiiigggghhhhtttt, and _n_u_m and _d_e_n_o_m are numbers specifying a ratio giving the relative posi- tion about which the titlebar is justified. The ratio is measured from left to right if the numera- tor is positive, and right to left if negative. A denominator of 0 indicates that the numerator should Rev.

Although a small set of defaults are supplied (unless the NNNNooooDDDDeeeeffffaaaauuuullllttttssss is specified), most users will want to have their most common operations bound to key and button strokes.

If the window is iconified, it will be deiconified if the variable WarpUnmapped is set or else ignored. f.warptoiconmgr string This function warps the pointer to the icon manager entry associated with the window containing the pointer in the icon manager specified by the argu- ment string.

String may be a number (e.g. "0" or "1"), the word "next" (indicating the current screen plus 1, skipping over any unmanaged screens), the word "back" (indicating the current screen minus 1, skipping over any unmanaged screens), or the word "prev" (indicating the last screen visited. f.winrefresh This function is similar to the f.refresh function except that only the selected window is refreshed. f.zoom This function is similar to the f.fullzoom function, except that the only the height of the selected win- dow is changed. MENUS Functions may be grouped and interactively selected using pop-up (when bound to a pointer button) or pull-down (when associated with a titlebutton) menus. Each menu specifica- tion contains the name of the menu as it will be referred to by f.menu, optional default foreground and background colors, the list of item names and the functions they should invoke, and optional foreground and background colors for Rev. Release 5 Page 26 TWM(1) AIX TWM(1) individual items: Menu "menuname" [ ("deffore":"defback") ] { string1 [ ("fore1":"backn")] function1 string2 [ ("fore2":"backn")] function2 . . . stringN [ ("foreN":"backN")] functionN } The menuname is case-sensitive. The optional deffore and defback arguments specify the foreground and background colors used on a color display to highlight menu entries. The string portion of each menu entry will be the text which will appear in the menu. The optional fore and back argu- ments specify the foreground and background colors of the menu entry when the pointer is not in the entry. These colors will only be used on a color display. The default is to use the colors specified by the MenuForeground and MenuBackground variables. The function portion of the menu entry is one of the functions, including any user-defined functions, or additional menus. There is a special menu named TwmWindows which contains the names of all of the client and twm-supplied windows. Selecting an entry will cause the WindowFunction to be exe- cuted on that window. If WindowFunction hasn't been set, the window will be deiconified and raised. ICONS Twm supports several different ways of manipulating iconi- fied windows. The common pixmap-and-text style may be laid out by hand or automatically arranged as described by the IconRegion variable. In addition, a terse grid of icon names, called an icon manager, provides a more efficient use of screen space as well as the ability to navigate among windows from the keyboard. An 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 button using the default iconify symbol will be displayed to the left of the name when the window is iconified. By default, clicking on an entry in the icon manager performs f.iconify. To change the actions taken in the icon manager, use the the iconmgr context when specify- ing button and keyboard bindings. Moving the pointer into the icon manager also directs key- board focus to the indicated window (setting the focus explicitly or else sending synthetic events NoTitleFocus is Rev. Release 5 Page 27 TWM(1) AIX TWM(1) set). Using the f.upiconmgr, f.downiconmgr f.lefticonmgr, and f.righticonmgr functions, the input focus can be changed between windows directly from the keyboard. BUGS The resource manager should have been used instead of all of the window lists. The IconRegion variable should take a list. Double clicking very fast to get the constrained move func- tion will sometimes cause the window to move, even though the pointer is not moved. If IconifyByUnmapping is on and windows are listed in IconManagerDontShow but not in DontIconifyByUnmapping, they may be lost if they are iconified and no bindings to f.menu "TwmWindows" or f.warpto are setup. FILES $HOME/.twmrc. $HOME/.twmrc /usr/lib/X11/twm/system.twmrc ENVIRONMENT VARIABLES DISPLAY This variable is used to determine which X server to use. It is also set during f.exec so that programs come up on the proper screen. HOME This variable is used as the prefix for files that begin with a tilde and for locating the twm startup file.
