X Version 11                                     xwininfo 1.1.6                                      XWININFO(1)

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.

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.

Environment

DISPLAY To get the default host and display number.

Options

-help Print out the `Usage:' command syntax summary.

-idwdid
This option allows the user to specify a target window wdid 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.

-namewdname
This option allows the user to specify that the window named wdname 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.

-d,-displayhost: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.
