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.

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).
