-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.
