NAME
XmTextGetTopCharacter — A Text function that accesses the position of
the first character displayed
SYNOPSIS
#include <Xm/Text.h>
XmTextPosition XmTextGetTopCharacter(
Widget widget);
DESCRIPTION
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

XmText(3).
RETURN
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).
