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 situations
where the root window is completely obscured. This
option specifies 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, window 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 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. 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 specifications 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).
The xwininfo program 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.
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
To get the default host and display number.
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.
