xwininfo - window information utility for X

SYNOPSIS

xwininfo [-help] [-id wdid] [-root] [-name wdname] [-int] [-children]
[-tree] [-stats] [-bits] [-events] [-size] [-wm] [-shape] [-frame]
[-all] [-english] [-metric] [-display host:dpy] [-version]

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 the screen's root
window.

OPTIONS

-help Print out the `Usage:' command syntax summary.

-id wdid
This option allows the user to specify a target window wdid
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 wdname
This option allows the user to specify that the window named
wdname 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.

-children
This option causes the root, parent, and children windows'
ids and names of the selected window 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 appearance of the selected
window. Information displayed includes the location of the
window, its width and height, its depth, border width, visual
id and 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.

-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.

-d, -display host:dpy
This option allows you to specify the server to connect to;
see X(7).

-version
This option indicates that xwininfo should print its version
information and exit.

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.
