NAME

       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.  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 id  This option allows the user to specify a target  window  id  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 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 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, 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, 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.
               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(7x).

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.
