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 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 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.
- -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.
