XmImUnsetFocus — An input manager function that notifies an input method that a widget has lost input

XmImUnsetFocus unsets a specified widget's focus, then notifies the  input  manager  that  the  specified
       widget has lost its input focus.

       Note  that  the  Text, TextField, and List widgets already call the XmImUnsetFocus internally. Therefore,
       further calls to the XmImUnsetFocus function for those widgets are unnecessary.

       widget    Specifies the ID of the widget registered with the input manager
