XWININFO(1) XWININFO(1)
NAME
xwininfo - window information utility for X
SYNOPSIS
xwininfo [-help] [-id id] [-root] [-name name] [-int] [-children] [-tree] [-stats] [-bits] [-events]
[-size] [-wm] [-shape] [-frame] [-all] [-english] [-metric] [-display display]
DESCRIPTION
Xwininfo is a utility for displaying information about windows. Various information is displayed
depending on which options are selected. If no options are chosen, -stats is assumed.
The user has the option of selecting the target window with the mouse (by clicking any mouse button
in the desired window) or by specifying its window id on the command line with the -id option. Or
instead of specifying the window by its id number, the -name option may be used to specify which win-dow window
dow is desired by name. There is also a special -root option to quickly obtain information on the
screen's root window.
OPTIONS
-help Print out the `Usage:' command syntax summary.
-id id This option allows the user to specify a target window id on the command line rather than
using the mouse to select the target window. This is very useful in debugging X applications
where the target window is not mapped to the screen or where the use of the mouse might be
impossible or interfere with the application.
-name name
This option allows the user to specify that the window named name is the target window on the
command line rather than using the mouse to select the target window.
-root This option specifies that X's root window is the target window. This is useful in situa-tions situations
tions where the root window is completely obscured.
-int This option specifies that all X window ids should be displayed as integer values. The
default is to display them as hexadecimal values.
-children
This option causes the root, parent, and children windows' ids and names of the selected win-dow window
dow to be displayed.
-tree This option is like -children but displays all children recursively.
-stats This option causes the display of various attributes pertaining to the location and appear-ance appearance
ance of the selected window. Information displayed includes the location of the window, its
width and height, its depth, border width, class, colormap id if any, map state, backing-store backingstore
store hint, and location of the corners.
-bits This option causes the display of various attributes pertaining to the selected window's raw
bits and how the selected window is to be stored. Displayed information includes the
selected window's bit gravity, window gravity, backing-store hint, backing-planes value,
backing pixel, and whether or not the window has save-under set.
-events This option causes the selected window's event masks to be displayed. Both the event mask of
events wanted by some client and the event mask of events not to propagate are displayed.
-size This option causes the selected window's sizing hints to be displayed. Displayed information
includes: for both the normal size hints and the zoom size hints, the user supplied location
if any; the program supplied location if any; the user supplied size if any; the program sup-plied supplied
plied size if any; the minimum size if any; the maximum size if any; the resize increments if
any; and the minimum and maximum aspect ratios if any.
-wm This option causes the selected window's window manager hints to be displayed. Information
displayed may include whether or not the application accepts input, what the window's icon
window # and name is, where the window's icon should go, and what the window's initial state
should be.
-shape This option causes the selected window's window and border shape extents to be displayed.
-frame This option causes window manager frames to be considered when manually selecting windows.
-metric This option causes all individual height, width, and x and y positions to be displayed in
millimeters as well as number of pixels, based on what the server thinks the resolution is.
Geometry specifications that are in +x+y form are not changed.
-english
This option causes all individual height, width, and x and y positions to be displayed in
inches (and feet, yards, and miles if necessary) as well as number of pixels. -metric and
-english may both be enabled at the same time.
-all This option is a quick way to ask for all information possible.
-display display
This option allows you to specify the server to connect to; see X(7).

BUGS
Using -stats -bits shows some redundant information.
The -geometry string displayed must make assumptions about the window's border width and the behavior
of the application and the window manager. As a result, the location given is not always correct.
