\fBXmTextGetTopCharacter\fP \(em A Text function that accesses the position of the first character displayed

\fBXmTextPosition \fBXmTextGetTopCharacter\fP\fR(
\fBWidget \fBwidget\fR\fR);

.SH "DESCRIPTION"
.PP
\fBXmTextGetTopCharacter\fP 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,
\fBXmNvalue\fP contains an empty string),
then \fBXmTextGetTopCharacter\fP returns 0\&.
.PP
Suppose that the \fBXmNtopCharacter\fP resource has been
set to a value greater than the number of characters in
the text widget\&. In this case,
\fBXmTextGetTopCharacter\fP returns an
\fBXmTextPosition\fR 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\&.
.IP "\fIwidget\fP" 10
Specifies the Text widget ID
.PP
For a complete definition of Text and its associated resources, see
\fBXmText\fP(3)\&.
.SH "RETURN"
.PP
Returns an \fBXmTextPosition\fR value that indicates the state of the
\fBXmNtopCharacter\fP resource\&. This is an integer number of characters
from the beginning of the text buffer\&. The first character position is
0 (zero)\&.
