.SH "NAME"

\fBXmWidgetGetBaselines\fP \(em Retrieves baseline information for

a widget

.iX "XmWidgetGetBaselines"

.SH "SYNOPSIS"

.PP

.nf

#include <Xm/Xm\&.h>

\fBBoolean \fBXmWidgetGetBaselines\fP\fR(

\fBWidget \fBwidget\fR\fR,

\fBDimension **\fBbaselines\fR\fR,

.fi

.SH "DESCRIPTION"

.PP

\fBXmWidgetGetBaselines\fP returns an array that

contains one or more baseline values associated with the

specified widget\&. The baseline of any given line of text

is a vertical offset in pixels from the origin of the

widget\&'s bounding box to the given baseline\&.

.IP "\fIwidget\fP" 10

Specifies the ID of the widget for which baseline values

are requested

.IP "\fIbaselines\fP" 10

Returns an array that contains the value of each

baseline of text in the widget\&.

The function allocates space to hold the returned array\&.

The application is responsible for managing the allocated space\&.

The application can recover this allocated space by calling \fBXtFree\fP\&.

.IP "\fIline_count\fP" 10

Returns the number of lines in the widget

.SH "RETURN"

.PP

Returns a Boolean value that indicates whether the

widget contains a baseline\&. If the value is True, the function returns

a value for each baseline of text\&. If it is False, the function

was unable to return a baseline value\&.
