NAME
xwininfo - window information utility for X
SYNOPSIS
xwininfo [-help] [-id id] [-root] [-name name] [-int] [-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 window is desired by name. There is also a special
-root option to quickly obtain information on X'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 situations 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.
-tree This option causes the root, parent, and children windows' ids
and names of the selected window to be displayed.
-stats This option causes the display of various attributes
pertaining to the location and appearance 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 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 supplied 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 if defined.
-frame This option causes window manager frames to not be ignored
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;
