XEV(1)              UNIX Programmer's Manual               XEV(1)


     xev - print contents of X events


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


     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 informa-
     tion that they contain; it is essentially a debugging and
     development tool, and should not be needed in normal usage.


     -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 win-

     -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

     -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.
