NAME

       geisview - view operation of the GEIS API

SYNOPSIS

       geisview [ -V ] [ -w windowid ] [ -b backend ]

DESCRIPTION

       This  manual  page  explains  the  geisview  program.  This  program  is a test driver for
       verifying the recognition and propagation of gestures through the GEIS API.

OPTIONS

       -V     Prints the version number of the program and exits.

       -w     Specifies  the  windowId  of  a  specific  window  to  associate   with   gestures.
              Particularly  useful  with  touchscreens.  If this argument is not set, the default
              action is to read gestures on the root window.

              The windowId can be determined using the program xwininfo.

       -b     Specifies the recognizer back end to use.

              The following are valid back end selections.

              dbus   Uses the DBus back end to connect to a running GEIS server (default).

              grail  Uses the dynamically loaded grail back end (default fallback).

              mock   Uses a mock back end for testing.

              xcb    Uses the pre-XI2 back end (may not be available).

ENVIRONMENT

       GEIS_DEBUG
              Enables GEIS library diagnostic messages on stderr.
