XEV(1)                               General Commands Manual                               XEV(1)

NAME
       xev - print contents of X events

SYNOPSIS
       xev  [-display  displayname]  [-geometry geom] [-bw pixels] [-bs {NotUseful,WhenMapped,Al-
       ways}] [-id windowid] [-root] [-s] [-name  string]  [-rv]  [-version]  [-event  event_mask
       [-event event_mask ...]]

DESCRIPTION
       Xev  creates  a window and then asks the X server to send it events whenever anything hap-
       pens 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 seeing what causes events to occur
       and to display the information that they contain; it is essentially a debugging and devel-
       opment 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, in-
               stead of creating a new window.

       -root   This option specifies that the root window should be monitored, instead of  creat-
               ing a new window.

       -s      This  option  specifies that save-unders should be enabled on the window. Save un-
               ders 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.

       -event event_mask
               Select which events to display.  The -event option can be specified multiple times
               to  select multiple types of events.  When not specified, all events are selected.
               Available event masks: keyboard mouse expose visibility structure substructure fo-
               cus property colormap owner_grab_button randr button

       -version
               This option prints the program version and exits.
