.SH "NAME"

\fBXmTextPosToXY\fP \(em A Text function that accesses the x and y position of a character position

.iX "XmTextPosToXY"

.iX "Text functions" "XmTextPosToXY"

.SH "SYNOPSIS"

.PP

.nf

#include <Xm/Text\&.h>

\fBBoolean \fBXmTextPosToXY\fP\fR(

\fBWidget \fBwidget\fR\fR,

\fBXmTextPosition \fBposition\fR\fR,

\fBPosition \fB*x\fR\fR,

\fBPosition \fB*y\fR\fR);

.fi

.SH "DESCRIPTION"

.PP

\fBXmTextPosToXY\fP accesses the \fIx\fP and \fIy\fP position,

relative to the upper

left corner of the Text widget, of a given character position in the

text buffer\&.

.PP

In the case of horizontal writing, the position is the origin of the

character\&. In the case of vertical writing, the position is the vertical

origin of the character\&.

.IP "\fIwidget\fP" 10

Specifies the Text widget ID

.IP "\fIposition\fP" 10

Specifies the character position in the text for which the \fIx\fP and \fIy\fP

position is accessed\&. This is an integer number of characters

from the beginning of the buffer\&. The first character position is 0 (zero)\&.

.IP "\fIx\fP" 10

Specifies the pointer in which the \fIx\fP 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\&.

.IP "\fIy\fP" 10

Specifies the pointer in which the \fIy\fP 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\&.

.PP

For a complete definition of Text and its associated resources, see

\fBXmText\fP(3)\&.

.SH "RETURN"

.PP

This function returns True if the character position is displayed in the

Text widget; otherwise, it returns False, and no \fIx\fP or \fIy\fP

value is returned\&.

.SH "RELATED"
