SYNOPSIS xnwm [ -cmsnftv2 ] [ @border ] [ %iconDelta ] [ fm=font ] [ fi=font ] [ fs=font ] [ l=op ] [ m=op ] [ r=op ] [ host:display ] [ =geometry ] DESCRIPTION The window manager is a process that allows the user of a display running the X window system to manipulate the windows on the screen. X implements the `desktop model' of overlapping windows; xnwm allows windows to be moved, iconified, and resized, allows the order of the windows in the `stack' of overlapping windows to be manipulated, and allows the keyboard focus to be attached to a window. X allows windows to contain other windows, but xnwm only manipulates the top-level windows and not any of the subwindows. The program xnwm takes arguments host and display, which refer the the host and display number. For example `xnwm amadeus:1' would start up the window manager on display one on the machine amadeus. By default, xnwm uses the host and display number stored in the environment variable DISPLAY, and therefore they are not normally specified. The program xnwm has 2 modes of operation, `normal' and `popup', In normal mode xnwm creates a menu window across the top of the screen. To perform an action, you click any mouse button in the appropriate menu box and then click the same button in the window you wish to affect. Xnwm also reserves certain button/key combinations and interprets them as operations on existing windows. The key combination is specified in the command line with some subset of the options: -c (Control), -m (Meta), and -s (Shift). For example, if you specify the options -cm then the Control and Meta keys must be down at the time a mouse button is depressed. The option -n (None) means that no buttons need be held down. This is discouraged since it means that applications will never receive unshifted mouse clicks. If no combination is specified in the command line, Meta is assumed. Note: the key combination is not necessary when X Version 10 19 July 1985 1
XNWM(1px) COMMAND REFERENCE XNWM(1px) using functions from the menu; it is only needed with the assigned button functions to distinguish window manager operations from operations destined for the application running within the window. The window manager normally takes control of the screen at various times to assure that the screen image remains correct while performing window manager operations. When this happens, requests from other applications are temporarily suspended until the window manager finishes the operation. The option -f (no freeze) disables this. If this option is specified, window outlines for Move and Resize will flicker rather than remaining solid, and the background behind popup windows (see later) will take longer to redraw. The options -t (thin), -v (vertical), and -2 (2 rows) control the format of the menu bar. In the absence of any of these, the menu extends across the entire screen. If the -t option is given, the menu bar will not extend fully across the screen; instead there will be room at the right (convenient for, for example, a clock window). If the -v option is used, the menu windows are stacked vertically instead of spread horizontally. The -2 option causes the menu windows to be in two rows, allowing room for a terminal window the height of the screen while still allowing menu access. Either of the last two options automatically selects the -t option. The menu is located in the upper left corner of the screen by default, but its location can be set with the =geometry option as usual with X applications. (Notice that there is no size component, position information is used only.) Xnwm will use reverse video for the menu, the cursor, icon text, and the frame around selected windows if the -r (reverse) option is used. The border width around selected windows can be changed with the @ argument; the default is 5 pixels. The default font for displaying text is ``8 x 13''. You can specify a different font with the fm= (Menu font), fi= (Icon font), and the fs= (Size window font) options. Initially, the left, middle, and right mouse buttons are bound to the operations Select, Raise, and Move. You can change these bindings with the l= (left), m= (middle), and r= (right) arguments. Each should be followed by one of the letters "srmilzc", representing, respectively, Select, Raise, Move, Iconify, Lower, resiZe, and Circulate. They may also be followed by nothing, in which case no function is bound to that key. X Version 10 19 July 1985 2
XNWM(1px) COMMAND REFERENCE XNWM(1px) Clicking any button that is not bound to the Select function in the background will cause the menu window to become visible if it has become covered by other windows. Double clicking the background will cause the menu to move back to its original position. In popup mode, the menu window is not normally displayed, but instead `pops up' when a particular button is pressed. To get popup mode, bind the letter ``p'' to any of the three buttons as described above. (You may also bind the other buttons as desired.) Whenever the bound button is clicked while the appropriate combination of control, meta, and shift keys is depressed, or any time a button that is not bound to the Select function is clicked in the background, the menu will appear beneath the cursor. You may then select any menu function you wish; after the operation is completed the menu will disappear. To make the menu disappear without performing any operation, just move the cursor out of the menu area. Note: the mouse button bound to the popup function may not be rebound using Assign. Using popup mode with complicated screen images and with no freeze (the -f option) may cause some difficulties if the menu obscures the image, since the applications will have to redraw their windows after the menu goes away. The available commands are described below. For any of these commands, if you press a button to start a command, and then want to abort the command, simply press one of the other buttons before releasing the first button. Select attaches the keyboard to a window, i.e., keyboard input will go to that window (hierarchy) even when the mouse is outside the window. It also Raises the selected window. Selecting the background will detach the keyboard from any window (actually, it attaches it to the background window). If no window is selected the keyboard input will go to the window which currently contains the mouse cursor. The selected window is highlighted by drawing a partial frame around the window. Selecting an icon allows the icon name to be edited: the delete key deletes the last character, control-U deletes the entire name, and other characters are appended to the current name. Typing a return restores the input focus to the most recent non-icon window selected. Raise raises the window to the top of any stack of overlapping windows. Move is used to move a window. If you apply it to a window, an outline will be moved with the mouse; when you release the button, the window will be moved. X Version 10 19 July 1985 3
XNWM(1px) COMMAND REFERENCE XNWM(1px) (De)Iconify will make a window into an icon. If the mouse is moved more than a threshold amount, or this is the first time the window has been iconified, the icon will appear at the location on the screen where the button is released. Otherwise, the icon will reappear at its previous location. This threshold may be changed with the %iconDelta option. Giving a negative value will disable this effect. The default is 5 pixels. (De)Iconify will make the original window reappear at its former position on the screen if it is applied to an icon. The name displayed in the icon can be edited by Selecting the icon. Lower will `push' the window you point at to the bottom of any stack of overlapping windows. Resize is used to resize a window by moving a corner or an edge. If you apply it to a window, a rubber banded outline of the window will be displayed and moving the mouse will change its size, leaving the opposite corner or other edges fixed. The corner or edge to be moved depends on the where the mouse is when the button is pressed. Imagine the window divided with grid of nine rectangles. If the mouse is in one of the four corner rectangles or the center rectangle, then the corner closest to the mouse will be moved; otherwise, the closest edge will be moved. When the button is released, the window will be resized. Circulate causes the lowest window in the stack of overlapping windows to be Raised ; successive applications will reveal every window in turn. Assign allows you to change the button bindings; to use it click any button in the Assign menu window and then click the same button in any other function to assign that function to that button. To remove the assignment from a button, double click the Assign window. X DEFAULTS AND OPTION SUMMARY MenuFont (fm=name) Set the default font for the menu.
