"XmTextGetTopCharacter" "Text functions" "XmTextGetTopCharacter"
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
For a complete definition of Text and its associated resources, see 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).
