XmTextRemove — A Text function that deletes the primary selection "XmTextRemove" "Text functions"

XmTextRemove deletes the primary selected text.  If there is a selection, this  routine  also  calls  the
       widget's   XmNvalueChangedCallback   and   verification   callbacks,  either  XmNmodifyVerifyCallback  or
       XmNmodifyVerifyCallbackWcs, or both. If both verification callback lists are registered,  the  procedures
       of  the  XmNmodifyVerifyCallback  list  are  executed  first  and  the  resulting  data  is passed to the
       XmNmodifyVerifyCallbackWcs callbacks.  This function may also call the XmNmotionVerifyCallback callback.

       widget    Specifies the Text widget ID.

       For a complete definition of Text and its associated resources, see XmText(3).
