xwininfo(1X)xwininfo(1X)NAMExwininfo - window information utility for X
SYNOPSISxwininfo [-help] [-id id] [-root] [-name name] [-int] [-children]
[-tree] [-stats] [-bits] [-events] [-size] [-wm] [-shape] [-frame]
[-all] [-english] [-metric] [-display display]
OPTIONS
Print out the `Usage:' command syntax summary. 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. 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. This option specifies
that X's root window is the target window. This is useful in situa‐
tions where the root window is completely obscured. This option speci‐
fies that all X window ids should be displayed as integer values. The
default is to display them as hexadecimal values. This option causes
the root, parent, and children windows' ids and names of the selected
window to be displayed. This option is like -children but displays all
children recursively. 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. 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, win‐
dow gravity, backing-store hint, backing-planes value, backing pixel,
and whether or not the window has save-under set. 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. This option causes the selected window's siz‐
ing 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. 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. This option causes the selected
window's window and border shape extents to be displayed. This option
causes window manager frames to be considered when manually selecting
windows. 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. 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.
This option is a quick way to ask for all information possible. This
option allows you to specify the server to connect to; see X(1X).
DESCRIPTION
The xwininfo program is a utility for displaying information about win‐
dows. 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.
EXAMPLE
The following is a sample summary taken with no options specified:
xwininfo: Window id: 0x60000f "xterm"
Absolute upper-left X: 2
Absolute upper-left Y: 85
Relative upper-left X: 0
Relative upper-left Y: 25
Width: 579
Height: 316
Depth: 8
Visual Class: PseudoColor
Border width: 0
Class: InputOutput
Colormap: 0x27 (installed)
Bit Gravity State: NorthWestGravity
Window Gravity State: NorthWestGravity
Backing Store State: NotUseful
Save Under State: no
Map State: IsViewable
Override Redirect State: no
Corners: +2+85 -699+85 -699-623 +2-623
-geometry 80x24+0+58
ENVIRONMENT
To get the default host and display number.
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 man‐
ager. As a result, the location given is not always correct.
