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 speci‐

fying 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 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.

-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 loca‐

tion 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 specifica‐

tions 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.
