       XmTextGetTopCharacter  — A Text function that accesses the position of the first character
       displayed "XmTextGetTopCharacter" "Text functions" "XmTextGetTopCharacter"


       #include <Xm/Text.h>
       XmTextPosition XmTextGetTopCharacter(
       Widget widget);


       XmTextGetTopCharacter accesses the position of the text at the top of the Text widget.  If
       there  is  no text in the Text widget (in other words, XmNvalue contains an empty string),
       then XmTextGetTopCharacter returns 0.

       Suppose that the XmNtopCharacter resource has been set to a value greater than the  number
       of  characters  in  the  text  widget.  In  this  case,  XmTextGetTopCharacter  returns an
       XmTextPosition value identifying the position of the first character in the last  line  of
       text  in  a multiline case; otherwise, it identifies the position of the last character in
       the line.

       widget    Specifies the Text widget ID

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


       Returns an XmTextPosition value that indicates the state of the XmNtopCharacter  resource.
       This  is  an integer number of characters from the beginning of the text buffer. The first
       character position is 0 (zero).
