NAME
       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.  Vari-
       ous 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 tar-
               get 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 us-
               ing the mouse to select the target window.

       -root   This  option  specifies that X's root window is the target win-
               dow.  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 hexadeci-
               mal 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  recur-
               sively.

       -stats  This option causes the display of various attributes pertaining
               to the location and appearance of the selected window.   Infor-
               mation displayed includes the location of the window, its width
               and height, its depth, border width, visual id and class,  col-
               ormap 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, back-
               ing-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 dis-
               played.  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 win-
               dow # 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. Ge-
               ometry 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.

       DISPLAY 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.
