xwininfo - window information utility for X 


xwininfo[-help] [-id id] [-root] [-name name] [-int][-children] [-tree] [-stats] [-bits] [-events] [-size] [-wm] [-shape][-frame] [-all][-english] [-metric][-display display] 


Xwininfois 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 withthe mouse (by clicking any mouse button in the desired window) or byspecifying its window id on the command line with the -id option.Or instead of specifyingthe window by its id number, the -name option may be used to specifywhich window is desired by name.There is also a special -root option to quickly obtain informationon the screen's root window. 


Print out the `Usage:' command syntax summary.

-id id
This option allows the user to specify a target window id on thecommand line rather than using the mouse to select the target window.This is very useful in debugging X applications where the targetwindow is not mapped to the screen or where the use of the mouse mightbe impossible or interfere with the application.

-name name
This option allows the user to specify that the window named nameis the target window on the command line rather than using the mouse toselect 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 asinteger values. The default is to display them as hexadecimal values.

This option causes the root, parent, and children windows' ids and names ofthe 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, visual id and class,colormap id if any, map state, backing-store hint, and location of the corners.

This option causes the display of various attributes pertaining tothe 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 ofevents 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 thezoom size hints, the user supplied location if any; the program suppliedlocation if any; the user supplied size if any; the program supplied size ifany; the minimum size if any; the maximum size if any; the resize incrementsif any; and the minimum and maximum aspect ratios if any.

This option causes the selected window's window manager hints to bedisplayed. Information displayed may include whether or not the applicationaccepts input, what the window's icon window # and name is, where the window'sicon should go, and what the window's initial state should be.

This option causes the selected window's window and border shape extents tobe 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 bedisplayed in millimeters as well as number of pixels, based on what theserver 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 bedisplayed in inches (and feet, yards, and miles if necessary) as well asnumber of pixels. -metric and -english may both be enabled at thesame time.

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).

To get the default host and display number.




Using -stats -bits shows some redundant information.

The -geometry string displayed must make assumptions about thewindow's border width and the behavior of the application and thewindow manager. As a result, the location given is not alwayscorrect.
