NAME
       XmStringComponentType -- Data type for compound string components

SYNOPSIS
       #include <Xm/Xm.h>

DESCRIPTION
       XmStringComponentType  is the data type specifying compound string component types. A com-
       pound string component identifies some part of a compound string, and can have a value and
       length.	A  compound  string  component can be one of the following types. These component
       types are grouped according to their length and value types.

       The following components have values of NULL and lengths of 0 (zero).

       XmSTRING_COMPONENT_SEPARATOR
		 This component usually maps to a newline or carriage return in displayed text.

       XmSTRING_COMPONENT_TAB
		 This component may be thought of as a text component containing  only	a  single
		 tab.

       XmSTRING_COMPONENT_LAYOUT_POP
		 The  layout direction is kept on a stack, with the current direction kept on top
		 of the stack. When this component is read, the most recently read layout  direc-
		 tion  is  popped  off the stack and replaced by the direction immediately before
		 it.

       XmSTRING_COMPONENT_END
		 This component marks the end of a compound string. No	other  components  should
		 follow.  If an application does not place an XmSTRING_COMPONENT_END component at
		 the end of an XmString, Motif automatically does it for the application.

       The following component has a value of XmDirection and the length of that direction.

       XmSTRING_COMPONENT_LAYOUT_PUSH
		 The layout direction is kept on a stack, with the current direction kept on  top
		 of  the  stack. This component replaces the current layout direction, and causes
		 another to be pushed onto the top of this stack.

       The following component has a value of XmStringDirection and the length of that direction.

       XmSTRING_COMPONENT_DIRECTION
		 This component sets the string  direction  by	overriding  the  previous  string
		 direction.

       The  following  components  have  values  of  type char * or some equivalent type, and the
       lengths of these types.

       XmSTRING_COMPONENT_LOCALE_TEXT
		 This component contains the multibyte text of a compound string.

       XmSTRING_COMPONENT_WIDECHAR_TEXT
		 This component contains the widechar text of a compound string.

       XmSTRING_COMPONENT_TEXT
		 This component contains the charset text of a compound string. Note that a  com-
		 pound	string	cannot	contain  both  charset and locale (multibyte or widechar)
		 text.

       XmSTRING_COMPONENT_RENDITION_BEGIN
		 This component marks the beginning of a new rendition. All text  following  this
		 component  will be rendered using this rendition as the primary one. If there is
		 already a rendition in effect, it is kept in memory and  used	to  fill  in  any
		 unspecified  values in the primary rendition. Renditions are kept until a corre-
		 sponding XmSTRING_COMPONENT_RENDITION_END component is encountered.

       XmSTRING_COMPONENT_RENDITION_END
		 This component signifies that the specified rendition will no longer be used  to
		 render  text,	and  will not be available to fill in unspecified values of newer
		 renditions.

       XmSTRING_COMPONENT_UNKNOWN
		 This component type signifies that the component contents belong to  an  unknown
		 component type.

       XmSTRING_COMPONENT_LOCALE
		 Use  this component to specify the locale in which an internationalized applica-
		 tion is to execute.  The only valid  character  string  for  this  component  is
		 _MOTIF_DEFAULT_LOCALE.

       XmSTRING_COMPONENT_TAG
		 For  charset  text,  this is the tag of the font to be used to display the text.
		 This tag is sometimes referred to as the charset tag or the fontlist tag.

       XmSTRING_COMPONENT_CHARSET
		 This component is obsolete and remains for compatibility with previous releases.
		 It has been replaced by XmSTRING_COMPONENT_TAG.

       XmSTRING_COMPONENT_FONTLIST_ELEMENT_TAG
		 This component is obsolete and remains for compatibility with previous releases.
		 It has been replaced by XmSTRING_COMPONENT_TAG.

       Some compound string  components  depend  on  values  defined  in  other  components.  The
       XmSTRING_COMPONENT_TAB  component  definition,  for example, depends on information in the
       XmSTRING_COMPONENT_RENDITION_BEGIN. To account for these dependencies, a typical  compound
       string will have its member components in the following order:

       [
	 [ XmSTRING_COMPONENT_LAYOUT_PUSH ]
	 [ XmSTRING_COMPONENT_RENDITION_BEGIN ]*
	 [ XmSTRING_COMPONENT_TAG | XmSTRING_COMPONENT_LOCALE ]
	 [ XmSTRING_COMPONENT_TAB ]*
	 [ XmSTRING_COMPONENT_DIRECTION ]
	 [ XmSTRING_COMPONENT_TEXT |
	   XmSTRING_COMPONENT_LOCALE_TEXT |
	   XmSTRING_COMPONENT_WIDECHAR_TEXT ]
	 [ XmSTRING_COMPONENT_RENDITION_END ]*
	 [ XmSTRING_COMPONENT_LAYOUT_POP ]
	 [ XmSTRING_COMPONENT_SEPARATOR ]
       ]*
       XmSTRING_COMPONENT_END
