XEV(1)                                                                                                                    XEV(1)



NAME
       xev - print contents of X events

SYNOPSIS
       xev  [-display  displayname] [-geometry geom] [-bw pixels] [-bs {NotUseful,WhenMapped,Always}] [-id windowid] [-s] [-name
       string] [-rv]

DESCRIPTION
       Xev creates a window and then asks the X server to send it events whenever anything happens to the  window  (such  as  it
       being  moved, resized, typed in, clicked in, etc.).  You can also attach it to an existing window.  It is useful for see-
       ing what causes events to occur and to display the information that they contain;  it  is  essentially  a  debugging  and
       development tool, and should not be needed in normal usage.

OPTIONS
       -display display
               This option specifies the X server to contact.

       -geometry geom
               This option specifies the size and/or location of the window, if a window is to be created.

       -bw pixels
               This option specifies the border width for the window.

       -bs {NotUseful,WhenMapped,Always}
               This  option  specifies  what  kind of backing store to give the window.  The default is NotUseful. Backing store
               refers to the the pixels saved off-screen when the X server maintains the contents of a window;  NotUseful  means
               that the xev process will redraw its contents itself, as necessary.

       -id windowid
               This option specifies that the window with the given id should be monitored, instead of creating a new window.

       -s      This option specifies that save-unders should be enabled on the window. Save unders are similar to backing store,
               but they refer rather to the saving of pixels off-screen when the current window  obscures  other  windows.  Save
               unders are only advisory, and are normally set for popup dialogs and other transient windows.

       -name string
               This option specifies the name to assign to the created window.

       -rv     This option specifies that the window should be in reverse video.
