NAME

       XmWidgetGetBaselines -- Retrieves baseline information for a widget

SYNOPSIS

       #include <Xm/Xm.h>
       Boolean XmWidgetGetBaselines(
       Widget widget,
       Dimension **baselines,
       int *line_count);

DESCRIPTION

       XmWidgetGetBaselines  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.

       widget	 Specifies the ID of the widget for which baseline values are requested

       baselines 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 XtFree.

       line_count
		 Returns the number of lines in the widget

RETURN

       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.

NAME

       XmTextPosToXY -- 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);

DESCRIPTION

       XmTextPosToXY  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 character 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  wid-
		 get 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.

       For a complete definition of Text and its associated resources, see XmText(3).

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.
