NAME

       XmDirectionToStringDirection -- A function that converts an XmDirection value to an XmStringDirection value

SYNOPSIS

       #include <Xm/Xm.h>
       XmStringDirection XmDirectionToStringDirection (dir)
	       XmDirection     dir;
       (void)

DESCRIPTION

       XmDirectionToStringDirection  converts  the specified XmDirection direction value to its equivalent XmStringDirection value.  Basically, if
       the XmDirection value has a horizontal direction specification, that horizontal element is used; otherwise, the XmStringDirection value	is
       interpreted as XmSTRING_DIRECTION_L_TO_R.  This function provides backward compatibility with the XmStringDirection data type.

       Note  that the Motif toolkit also contains an XmStringDirectionToDirection routine to convert an XmStringDirection value to its XmDirection
       equivalent.

       dir	 Specifies the XmDirection value to be converted.

RETURN

       Returns the following XmStringDirection values:

       XmSTRING_DIRECTION_R_TO_L
		 If the dir argument has a right to left horizontal direction value in it, for example XmRIGHT_TO_LEFT_TOP_TO_BOTTOM.

       XmSTRING_DIRECTION_L_TO_R
		 If the dir argument has a left to right horizontal direction in it, for example XmLEFT_TO_RIGHT_TOP_TO_BOTTOM, or if the horizon-
		 tal direction value in the dir argument is ambiguous, such as in the XmTOP_TO_BOTTOM value.

       XmSTRING_DIRECTION_DEFAULT
		 If there was no horizontal direction specified.

NAME

       XmDirection -- Data type for the direction of widget components

SYNOPSIS

       #include <Xm/Xm.h>

DESCRIPTION

       XmDirection  is the data type specifying the direction in which the system displays subwidgets, children of widgets, or other visual compo-
       nents that are to be laid out.  This data type also affects traversal order within tab groups.

       XmDirection is implemented as an unsigned char bit mask.  The horizontal and vertical directions  can  be  specified  independent  of  each
       other.  XmDirection also specifies the precedence of the horizontal and vertical directions relative to each other. For example, a value of
       XmRIGHT_TO_LEFT_TOP_TO_BOTTOM lays out a component horizontally from right to left first, then vertically top to bottom.

       XmDirection provides the following masks, each of which corresponds to a particular bit in XmDirection:

	  o  XmRIGHT_TO_LEFT_MASK

	  o  XmLEFT_TO_RIGHT_MASK

	  o  XmTOP_TO_BOTTOM_MASK

	  o  XmBOTTOM_TO_TOP_MASK

	  o  XmPRECEDENCE_HORIZ_MASK

	  o  XmPRECEDENCE_VERT_MASK

       In addition to the preceding single bit masks, XmDirection also provides the following multiple bit masks. These  multiple  bit	masks  are
       particularly useful as arguments to XmDirectionMatchPartial:

	  o  XmHORIZONTAL_MASK

	  o  XmPRECEDENCE_MASK

	  o  XmVERTICAL_MASK

       Motif also provides the following enumerated constants for specifying various combinations of directions:

       XmRIGHT_TO_LEFT_TOP_TO_BOTTOM
		 Specifies that the components are laid out from right to left first, then top to bottom.

       XmLEFT_TO_RIGHT_TOP_TO_BOTTOM
		 Specifies that the components are laid out from left to right first, then top to bottom.

       XmRIGHT_TO_LEFT_BOTTOM_TO_TOP
		 Specifies that the components are laid out from right to left first, then bottom to top.

       XmLEFT_TO_RIGHT_BOTTOM_TO_TOP
		 Specifies that the components are laid out from left to right first, then bottom to top.

       XmTOP_TO_BOTTOM_RIGHT_TO_LEFT
		 Specifies that the components are laid out from top to bottom first, then right to left.

       XmTOP_TO_BOTTOM_LEFT_TO_RIGHT
		 Specifies that the components are laid out from top to bottom first, then left to right.

       XmBOTTOM_TO_TOP_RIGHT_TO_LEFT
		 Specifies that the components are laid out from bottom to top first, then right to left.

       XmBOTTOM_TO_TOP_LEFT_TO_RIGHT
		 Specifies that the components are laid out from bottom to top first, then left to right.

       XmTOP_TO_BOTTOM
		 Specifies that the components are laid out from top to bottom.  If horizontal direction is important, do not use this constant.

       XmBOTTOM_TO_TOP
		 Specifies that the components are laid out from bottom to top.  If horizontal direction is important, do not use this constant.

       XmDEFAULT_DIRECTION
		 Specifies that the components are laid out according to the default direction. (This constant is primarily for widget writers.)

       XmLEFT_TO_RIGHT
		 Specifies that the components are laid out from left to right.  If vertical direction is important, do not use this constant.

       XmRIGHT_TO_LEFT
		 Specifies that the components are laid out from right to left.  If vertical direction is important, do not use this constant.
