NAME

       XmDirection  — Data type for the direction of widget components "XmDirection" "data types"
       "XmDirection"

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 components 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:

          •  XmRIGHT_TO_LEFT_MASKXmLEFT_TO_RIGHT_MASKXmTOP_TO_BOTTOM_MASKXmBOTTOM_TO_TOP_MASKXmPRECEDENCE_HORIZ_MASKXmPRECEDENCE_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:

          •  XmHORIZONTAL_MASKXmPRECEDENCE_MASKXmVERTICAL_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.
