NAME

       XmStringIsVoid -- A compound string function that provides information on the existence of non-zero-length text components, tab components,
       or separator components

SYNOPSIS

       #include <Xm/Xm.h>
       Boolean XmStringIsVoid(
       XmString s1);

DESCRIPTION

       XmStringIsVoid returns a Boolean value indicating whether or not string s1 is void.

       s1	 Specifies the compound string

RETURN

       Returns True if any non-zero-length text components, tab components, or separator components exist in s1.  That is,  the  function  returns
       True if the string has no text, tabs, or separators.  If s1 contains the NULL string, the function returns True.

NAME

       XmString -- Data type for a compound string

SYNOPSIS

       #include <Xm/Xm.h>

DESCRIPTION

       XmString  is the data type for a compound string.  Compound strings consist of a sequence of components, including, but not limited to, the
       following:

	  o  XmSTRING_COMPONENT_SEPARATOR

	  o  XmSTRING_COMPONENT_TAB

	  o  XmSTRING_COMPONENT_LAYOUT_POP

	  o  XmSTRING_COMPONENT_DIRECTION

	  o  XmSTRING_COMPONENT_LAYOUT_PUSH

	  o  XmSTRING_COMPONENT_CHARSET

	  o  XmSTRING_COMPONENT_FONTLIST_ELEMENT_TAG

	  o  XmSTRING_COMPONENT_LOCALE

	  o  XmSTRING_COMPONENT_LOCALE_TEXT

	  o  XmSTRING_COMPONENT_TAG

	  o  XmSTRING_COMPONENT_TEXT

	  o  XmSTRING_COMPONENT_END

	  o  XmSTRING_COMPONENT_RENDITION_BEGIN

	  o  XmSTRING_COMPONENT_RENDITION_END

	  o  XmSTRING_COMPONENT_UNKNOWN

	  o  XmSTRING_COMPONENT_WIDECHAR_TEXT

       and also a rendition tags table, text, and text component.  When a compound string is displayed, the rendition tags and the  direction  are
       used to determine how to display the text.

       Calling	XtGetValues for a resource whose type is XmString yields a copy of the compound string resource value.	The application is respon-
       sible for using XmStringFree to free the memory allocated for the copy.

       Please see the XmStringComponentType reference page for more detail about compound string components, and for a description of the order in
       which the components should appear in a compound string.  Refer to the XmRenderTable reference page for a description of the algorithm that
       associates the rendition tags used for displaying a compound string text component with a rendition in a render table.
