NAMEXmTextPosToXY — A Text function that accesses the x and y position of a
character position
SYNOPSIS
#include <Xm/Text.h>
Boolean XmTextPosToXY(
Widget widget,
XmTextPosition position,
Position *x,
Position *y);
DESCRIPTIONXmTextPosToXY accesses the x and y position, relative to the upper left
corner of the Text widget, of a given character position in the text
buffer.
In the case of horizontal writing, the position is the origin of the
character. In the case of vertical writing, the position is the verti‐
cal origin of the character.
widget Specifies the Text widget ID
position Specifies the character position in the text for which the x
and y position is accessed. This is an integer number of
characters from the beginning of the buffer. The first char‐
acter position is 0 (zero).
x Specifies the pointer in which the x position is returned.
The returned position is the distance from the left side of
the widget to the left border of the character. This value
is meaningful only if the function returns True.
y Specifies the pointer in which the y position is returned.
The returned position is the distance from the top of the
widget to the character's baseline. This value is meaningful
only if the function returns True.

RETURN
This function returns True if the character position is displayed in
the Text widget; otherwise, it returns False, and no x or y value is
returned.
